Tides 101: How to Read a Tide Chart, High Tide, Low Tide & Fishing Tides

If you fish, kayak, boat, explore the marsh, walk the beach, or spend any amount of time around the Georgia and Northeast Florida coast, learning how to understand the tides is one of the most useful skills you can develop.

You don't have to be a marine scientist.

You don't have to memorize a bunch of complicated terminology.

You simply need to understand what the water is doing, when it is going to change, and how those changes affect the places you plan to fish or explore.

That starts with learning how to read a tide chart.

Whether you've searched for "tides near me," "high tide today," "low tide today," "fishing tides," or simply wondered what all those numbers on a tide chart mean, this guide will walk you through it.

For anglers along the Georgia coast and Northeast Florida, tides are especially important. Our coastline is filled with tidal rivers, creeks, marshes, flats, inlets, oyster areas and sounds. As the tide rises and falls, water moves through all of those environments, changing depth, current, access and where bait and fish may be found.

At 912 Coastal, we believe learning to read the water is just as important as learning what lure to throw.

Let's start with the basics.

What Is a Tide?

A tide is the regular rise and fall of ocean and coastal water levels caused primarily by the gravitational forces of the Moon and Sun.

NOAA describes tides as very long-period waves that move through the oceans. When the crest of that tidal wave reaches a particular location, you experience high tide. When the trough reaches that location, you experience low tide.

The difference between the height of high tide and low tide is called the tidal range.

For example, imagine a tide chart showing:

High tide: 7:15 AM — 8.2 feet
Low tide: 1:32 PM — 1.1 feet

The tidal range between those two water levels would be 7.1 feet.

That doesn't mean the water simply rises 7.1 feet straight up and then drops 7.1 feet straight down.

The entire tidal system is constantly moving through the coastal environment.

And that's where things get interesting for anglers.

High Tide vs. Low Tide

The two terms you'll see most often on a tide chart are high tide and low tide.

What is high tide?

High tide, also called high water, is the maximum height reached by the rising tide at a particular location.

High tide can change how much water covers:

• Grass flats

• Oyster bars

• Mud flats

• Sandbars

• Marsh edges

• Shallow creeks

• Boat ramps

• Shorelines

• Beaches

An area that may be too shallow to access on a low tide can become completely flooded on a high tide.

For anglers, that can be extremely important.

Fish don't necessarily stay in the exact same location throughout the entire tide cycle.

As water covers new areas, bait and predators can move with it.

What is low tide?

Low tide, or low water, is the minimum height reached by the falling tide at a particular location.

Low tide can expose areas that were underwater only a few hours earlier.

That gives anglers an opportunity to see structure that normally stays submerged.

You may suddenly notice:

• Oyster bars

• Creek channels

• Sandbars

• Mud flats

• Drainage cuts

• Grass edges

• Deeper holes

• Current channels

This is one reason extremely low tides can be useful for learning a new area.

You're getting a look at the underwater landscape.

How Often Do High Tide and Low Tide Happen?

Many coastal locations experience approximately two high tides and two low tides during a lunar day, which is about 24 hours and 50 minutes.

That means consecutive high tides are separated by roughly 12 hours and 25 minutes on average, although actual timing varies by location and tidal conditions.

This is why the tide tomorrow isn't simply going to occur at the exact same time as today's tide.

The Moon's position changes relative to Earth, causing the timing of the tidal cycle to shift from day to day.

That's also why checking the tide chart for the specific location and date matters.

What Is an Incoming Tide?

An incoming tide generally refers to the period when water is rising.

NOAA uses the term flood current for tidal current moving toward the shore or up a tidal river or estuary.

Along the Georgia and Northeast Florida coast, an incoming tide can push water into:

• Tidal creeks

• Marshes

• Flats

• Backwaters

• Estuaries

• Shallow feeding areas

That can move bait and change where predators position themselves.

For an inshore angler, the important question isn't simply:

"Is the tide coming in?"

Ask:

"Where is the incoming water going?"

That question can help you find areas where water is concentrating bait.

What Is an Outgoing Tide?

An outgoing tide occurs as water falls and moves back toward the ocean.

NOAA refers to this tidal current as an ebb current.

This is especially important in tidal creeks and marsh systems.

Think about what happens when the tide drains out of a shallow marsh.

Water leaves the marsh through:

• Creek mouths

• Drainage cuts

• Small channels

• Points

• Deeper holes

• Oyster-lined channels

Anything living in that water has to move with it or adjust to the changing conditions.

That includes shrimp, crabs, baitfish and predators.

This is why an outgoing tide can create concentrated feeding opportunities around creek mouths and drainage areas.

Instead of looking at the tide as simply "high" or "low," start looking at where the water is going.

That's a much more useful way to think about tides.

What Is Slack Tide?

One of the most misunderstood terms in fishing is slack tide.

Slack water is the period when tidal current is at or near its minimum as the current changes direction.

NOAA points out that slack water is not necessarily identical to the exact time of high tide or low tide in every location. The relationship between water level and current varies depending on the local tidal system.

That's important.

A tide chart tells you about water level.

A current prediction tells you about water movement.

Those are related, but they are not exactly the same thing.

For fishing, this distinction matters.

You may have a high tide at one time but still have meaningful current before or after that point.

That's why experienced anglers often pay attention to both the tide height and the current.

How to Read a Tide Chart

This is the part that every new coastal angler should learn.

A typical tide chart gives you several pieces of information.

You may see something like:

6:42 AM — High — 7.8 ft
12:58 PM — Low — 1.2 ft
7:05 PM — High — 8.1 ft

Here's what it means.

1. Time

The first number tells you when the predicted high or low water occurs.

Always make sure you're looking at the correct date and time zone.

NOAA's tide prediction system allows users to select the time zone and other display settings when generating predictions.

2. High or Low

The label tells you whether the prediction represents:

High water

or

Low water

3. Height

The number tells you the predicted water level relative to the tidal datum used by that station.

For example:

High — 7.8 ft

doesn't mean every location around you will have exactly 7.8 feet of water.

It applies to that specific tide station and its reference datum.

This is one reason you should select a tide station that is appropriate for the area you're actually visiting.

4. Location

This is extremely important.

Don't simply search "tides near me" and assume the first tide station you see represents every creek, beach, inlet and river nearby.

Tides can vary significantly between locations.

A station at an inlet may not represent conditions inside a tidal creek several miles away.

Use the tide station that best corresponds to the water you're actually planning to fish or navigate.

NOAA's tide prediction system includes thousands of locations and allows users to select individual stations.

What Does "Tides Near Me" Really Mean?

Searches for "tides near me" are extremely common.

But there's an important difference between finding a tide chart and finding the right tide chart.

If you're fishing around St. Marys, Georgia, for example, you may be dealing with:

• St. Marys River

• Cumberland Sound

• Crooked River

• Tidal creeks

• Nearby marshes

• Coastal inlets

Those areas are connected, but they don't necessarily experience identical water levels and current behavior at exactly the same time.

The same principle applies throughout Northeast Florida.

If you're fishing Fernandina Beach, Amelia Island, Jacksonville, the St. Johns River or another coastal location, choose a tide station that makes sense for the specific area you're using.

"Tides near me" is a good starting search. Choosing the correct tide station is the important next step.

How to Use a Tide Chart for Fishing

This is where reading a tide chart becomes much more useful.

Don't look at a tide chart and simply think:

High tide = good.

or

Low tide = bad.

Fishing is rarely that simple.

Instead, look for water movement, structure, bait and access.

Ask yourself:

Where will the water be moving?

Where will bait be moving?

Which areas will become covered with water?

Which areas will drain?

Where will current concentrate?

Where can fish position themselves to take advantage of that movement?

These questions are much more useful than simply asking what tide is "best."

Why Moving Water Matters to Inshore Anglers

Tides create changes in water level and tidal currents.

Those changes can move:

• Shrimp

• Crabs

• Mullet

• Menhaden

• Small baitfish

• Other forage

Predatory fish respond to those changes.

That's one reason tide and current are so important to inshore fishing.

For example, imagine a shallow marsh creek connected to a larger channel.

During an incoming tide, water moves into the creek.

During the outgoing tide, water drains back toward the larger channel.

A predator doesn't necessarily have to search every inch of the marsh.

It can position itself near a creek mouth or current seam and wait for food to come through.

That's the basic idea behind fishing the tide.

You're not necessarily trying to catch fish because the tide is "high."

You're trying to understand what the moving water is doing.

Incoming Tide Fishing

An incoming tide can bring water and forage into shallow areas.

Look for:

• Flooded grass

• Creek mouths

• Shallow flats

• Oyster edges

• Points

• Current seams

• Areas where deeper water meets shallow water

As the water rises, fish may move into areas that were previously too shallow.

This is particularly important in shallow marsh environments.

If you know a flat holds bait at higher water, the incoming tide may give you an opportunity to intercept fish moving onto that flat.

Outgoing Tide Fishing

Outgoing water can be especially interesting because it drains shallow areas.

Look for:

• Creek mouths

• Marsh drains

• Channel edges

• Oyster points

• Deeper holes

• Current seams

• Places where several small drains combine

The key is to identify where water is being forced through a smaller opening.

Those locations can concentrate forage.

Our guides on Red Fish, Sheepshead, flounder fishing, trout fishing and St. Marys fishing all come back to the same basic principle: don't just look at the spot — look at the water moving through the spot.

Does a Higher Tide Mean Better Fishing?

Not necessarily.

A higher tide can open up shallow habitat and allow fish to move into areas that are inaccessible at lower water.

But a lower tide can expose structure and concentrate water into channels.

Both can create opportunities.

The important question is:

What does that particular tide do to the location you're fishing?

For example:

A high tide may flood a grass flat.

A falling tide may drain that flat.

The high tide may give fish access to the flat.

The outgoing tide may give predators an opportunity to intercept bait leaving it.

Same location.

Different tide.

Different opportunity.

That's why there isn't one universal "best tide for fishing."

Tide Height vs. Tide Movement

This is one of the biggest lessons new anglers can learn.

Tide height tells you where the water level is going.

Tidal current tells you how water is moving.

You want to understand both.

A tide chart might show a high tide of 8 feet.

That tells you the predicted water level at that station.

It doesn't automatically tell you how strong the current will be at your exact fishing location.

NOAA specifically distinguishes tides as vertical water-level changes from currents as horizontal water movement.

For anglers, that's a major distinction.

How Weather Can Change What You See

Tide predictions are based on astronomical forces, but the actual water level you experience can be affected by weather and other environmental conditions.

Wind, atmospheric pressure, storms and other conditions can push water higher or lower than the predicted astronomical tide.

That means a tide chart should be treated as an important planning tool — not a guarantee of the exact water level you'll see at every moment.

This becomes particularly important during strong weather systems, tropical systems and coastal flooding situations.

Always check current marine and weather information before heading onto the water.

Spring Tides and Neap Tides

You may also hear anglers talk about spring tides and neap tides.

Spring tides

Spring tides occur around the new and full moon phases and generally produce a larger tidal range.

That means higher high tides and lower low tides compared with more moderate tidal periods.

Neap tides

Neap tides occur around the first and third quarter moon phases and generally produce a smaller tidal range.

The difference can matter to anglers because a larger tidal range can produce different amounts of water movement through marshes, creeks and inlets.

NOAA notes that tidal current strength is influenced by lunar phase, with stronger spring currents around full and new moons and weaker neap currents around first and third quarter phases.

How to Find Tide Predictions

For U.S. coastal waters, NOAA is one of the primary resources for tide predictions.

NOAA's online system provides tide predictions for thousands of locations and allows users to view predictions by date, time zone, units and other settings.

When checking a tide chart, always verify:

1. The date

2. The location

3. The tide station

4. The time zone

5. High and low water times

6. Predicted heights

7. Whether you're looking at tides or tidal currents

That simple checklist can prevent a lot of confusion.

Tides Along the Georgia Coast

The Georgia coast is a particularly interesting environment for learning about tides.

Our coastline includes extensive salt marshes, tidal creeks, rivers, sounds, barrier islands and inlets.

Around St. Marys, Georgia, anglers have access to the St. Marys River, Crooked River, Cumberland Sound, Cumberland Island and numerous tidal creeks and marsh systems.

That makes understanding tides especially valuable.

Our St. Marys fishing guide explores the area's tidal rivers, creeks, marshes and coastal waters in greater detail.

And if you're looking for places to actually fish, our Best Places to Fish in St. Marys guide can help you think about structure, access and different types of fishing water.

Tides Around Cumberland Island

Cumberland Island is surrounded by water that is heavily influenced by tides.

For anglers, kayakers and boaters, the changing water level can dramatically change access to shallow areas, creeks and marsh habitat.

If you're planning a trip to Cumberland Island, don't just check the weather.

Check the tide.

Our Cumberland Island Fishing Guide is a useful next step for anglers who want to explore the area's fishing opportunities.

Tides and Fort Clinch

The same principle applies around Fort Clinch and the St. Marys Inlet.

The jetties, inlet and surrounding water are influenced by strong tidal movement.

That creates current seams, eddies, changing water levels and moving forage.

Our Fort Clinch Jetties Fishing Guide goes deeper into how anglers can think

about structure, current and tide around this area.

Remember that inlet and jetty conditions can become dangerous, especially when wind, waves and strong tidal currents combine.

Tides and Trout Fishing

Spotted seatrout are another excellent example of why understanding tides matters.

Trout may use creek mouths, marsh edges, oyster areas, deeper channels and other structure depending on conditions.

As the tide changes, bait movement and current can change as well.

Our Trout Fishing in St. Marys guide takes a closer look at finding trout around local tidal habitat.

The important lesson is the same:

Don't just find the fish. Learn why they're there.

Tides and Flounder Fishing

Flounder are another species where understanding water movement can help.

Because they are bottom-oriented ambush predators, anglers often look at areas where current, structure and changes in depth come together.

Our Flounder Fishing in St. Marys guide goes deeper into fishing the bottom, creek mouths, channels and tidal movement.

An outgoing tide can be particularly interesting when shallow areas drain into deeper water.

Tides and Inshore Fishing 101

If you're completely new to coastal fishing, start with our Inshore Fishing 101 guide.

Inshore fishing isn't simply about throwing a lure into saltwater.

It's about learning the relationship between:

Water + Tide + Current + Structure + Bait + Fish

Once you understand those relationships, unfamiliar water becomes easier to read.

A tide chart gives you one piece of that puzzle.

Your job as an angler is to connect it to what you see on the water.

A Simple Tide Strategy for Beginners

If you're new to reading tides, don't make it complicated.

Try this.

Step 1: Check the tide chart

Write down the next high tide and low tide.

Step 2: Look at the tide height

Is the range small or large?

Step 3: Identify the direction

Is the water rising or falling when you plan to fish?

Step 4: Look at your fishing spot

Ask where the water will enter or leave.

Step 5: Find structure

Look for:

• Creek mouths

• Oyster bars

• Points

• Grass edges

• Channel edges

• Drainage cuts

• Deeper holes

Step 6: Look for bait

Watch for shrimp, mullet, baitfish, crabs and other forage.

Step 7: Watch the current

Don't just look at the clock.

Look at the water.

Is it moving?

Where is it moving?

How fast?

Where does it speed up?

Where does it slow down?

Step 8: Record what happens

Write down:

• Date

• Tide

• Tide height

• Location

• Weather

• Wind

• Water clarity

• Bait activity

• Species caught

• Lure or bait

• Time of the catch

Do this consistently and you'll eventually begin building your own fishing patterns.

The Tide Isn't the Whole Story

One of the biggest mistakes anglers make is believing that the tide alone determines whether fish will bite.

It doesn't.

Tide is one factor.

You should also consider:

• Weather

• Wind

• Water temperature

• Water clarity

• Salinity

• Season

• Bait

• Structure

• Time of day

• Fishing pressure

• Target species

A great tide with terrible weather may not produce the trip you expected.

A mediocre tide combined with perfect bait, favorable wind and active fish can sometimes produce a memorable day.

That's why 912 Coastal takes a bigger-picture approach to coastal fishing.

Learn the water.

The Biggest Tide Mistakes New Anglers Make

Mistake #1: Assuming every tide station is the same

It's not.

Choose a station appropriate for the water you're actually using.

Mistake #2: Thinking high tide automatically means good fishing

High tide simply describes water level.

Fish respond to many factors.

Mistake #3: Ignoring current

Water movement can be just as important as water height.

Mistake #4: Looking only at the tide time

Look at the entire tide cycle.

Mistake #5: Ignoring structure

The tide matters because it changes what happens around structure and habitat.

Mistake #6: Not recording results

Your own fishing log can become one of your most valuable resources.

How to Start Reading Tides Like an Angler

The next time you see a tide chart, don't just look for the words high and low.

Look for the story.

Where will the water be?

Where will it come from?

Where will it go?

What areas will flood?

What areas will drain?

Where will bait move?

Where will current increase?

Where will fish have an opportunity to feed?

That's how you move from simply checking the tide to actually reading the tide.

And that is a skill that can make you a better inshore angler.

Final Thoughts: Learn the Tide, Read the Water

Whether you searched for tides near me, high tide today, low tide today, how to read a tide chart, or simply want to become a better coastal angler, understanding tides is one of the best places to start.

The tide isn't just a number on an app.

It is part of the constantly changing coastal environment.

It changes water depth.

It moves current.

It moves bait.

It changes access.

It exposes structure.

It floods shallow habitat.

And it influences where fish can find food.

For anglers along the Georgia and Northeast Florida coast, learning to recognize those changes can completely change the way you approach a fishing spot.

Don't just ask:

"What's the tide?"

Start asking:

"What is the tide doing to the water in front of me?"

That's when tide charts start becoming useful.

That's when fishing starts becoming less about guessing and more about understanding.
