How to Read a Tide Chart for Fishing

Most people open a tide chart looking for high tide. That's the wrong number.

What matters isn't where the water is, it's whether it's moving and how fast. Moving water carries food. It lifts sand crabs and worms out of the beach, pulls baitfish off structure, and funnels the whole lot into lanes you can predict. The fish worked this out long before we did. They feed on the move and rest on the slack.

Why is slack tide the worst time to fish?

At the top and bottom of the tide there's a stretch where the water pauses before it turns. Nothing's being carried anywhere. On most beaches that's the deadest part of the whole cycle, and it's also, annoyingly, the time printed in bold on every tide table.

Fishing normally switches on in the first hour after the water starts moving again, builds while the flow is strongest, and fades as it slackens toward the next turn.

When is the best time to fish a tide?

The middle of it. Between a high and the next low, the water doesn't move at a steady speed. It starts slow, peaks around the middle, then slows again.

The rule of twelfths is the quick way to picture it. Of the total range, roughly one twelfth moves in the first hour, two in the second, three in the third, three in the fourth, two in the fifth, one in the sixth.

Which means hours three and four carry half the entire movement between them. That's your window. If you've got two hours to fish and a six hour tide, fish those two.

This is arithmetic, not folklore, and it's the most useful thing on a tide chart once you know to look for it.

Do bigger tides mean better fishing?

Not automatically. A big tide moves more water and moves it faster. Around the new and full moon the range is at its biggest, which is called a spring tide and has nothing to do with the season. Around the quarter moons it's smallest, called a neap.

But a big spring tide on an exposed beach can throw so much sand and weed into the water that nothing feeds, and it'll drag a 4 oz sinker down the beach no matter what you do. A modest tide on a calm day is often the more fishable one. What you want is enough movement to bring food through without turning the water to soup.

How do you plan a session around the tide?

Look at the chart the night before. Find the turn, count forward about two hours, and that's roughly when you want a bait in the water. Then check swell and wind, because a perfect tide on a beach with eight feet of unfishable surf isn't a fishing trip, it's a drive.

Our sister site USTideCharts does this arithmetic for you. It scores every two hour window at a given spot using live NOAA tide data, wind and moon phase, so you can see the good windows for the week without counting twelfths in your head. It's free, and it's the first thing to check before you spend a dollar on tackle or a tank of fuel on a drive.

Common questions

Is high tide or low tide better for surf fishing?

Neither on its own. What matters is that the water's moving. On most beaches the most productive stretch is the middle of a tide, in either direction, because that's when the flow is fastest.

How long before the tide should I arrive?

Aim to be fishing about an hour after the turn, so you're already set up when the flow builds. Turning up at the turn itself usually means you spend the best part of the window rigging up.

Do I need a heavier sinker on a big tide?

Usually. A spring tide moves water faster, so a weight that held through a neap will walk. Carry a heavier size for the middle of the cycle and change down as it slackens.
