Short answer
There is no single best tide for every place and species. In general, moving water is better than slack water, because current tends to get bait and predators active. Some anglers prefer the incoming tide, others the outgoing, and the best choice often depends on the spot, season, wind, and the fish you are after.
Why moving water matters
Tidal current moves baitfish and crustaceans, and predators often position where the flow brings food to them. Around the peak of high or low tide there can be a period when water barely moves. During that slack period, baitfish activity often drops and feeding may slow. Most guidance suggests focusing on the hours between the peaks, when water is flowing.
Always check a local tide chart. Timing and strength of tides differ a lot from one coast, bay and inlet to the next, and the times printed for a major reference port may not match your spot.
Incoming (rising) tide
As the tide rises, water pushes into bays, creeks and onto flats, bringing bait and crustaceans with it. Game fish often follow into the shallows. Anglers targeting inshore species such as red drum, pompano and spotted seatrout often try shallow bays and flats on the rising tide, before the peak of high water.
Clean, cooler ocean water also tends to push in with the flood in many areas, which some anglers value, though this varies by location.
Outgoing (falling) tide
When the tide drops, water drains out of marshes, flats and creeks, carrying bait with it. Fish often stage at creek mouths, channel edges, points and drains to ambush what is flushed out. Some experienced anglers report that outgoing water has been better for them than incoming, which goes against a common belief that rising water is always best. This is a good example of why local knowledge beats a blanket rule.
Slack tide
Slack water is when the flow pauses and reverses. Fishing is often slower, but not hopeless. Points, sloughs and deeper holes can still hold fish, and you can use the time to change spots or rest. The tide turn itself can also trigger a bite in some places, so stay alert.
The rule of twelfths
The rule of twelfths is a rough way to estimate how much the water level changes each hour between low and high tide, assuming a roughly six-hour tide cycle. In the first hour the water moves about one twelfth of the total range, then two twelfths, then three, three, two and one. That means the strongest flow is generally in the middle two hours, with slower movement near the start and end of the tide.
It is only an approximation. Local geography and weather can change real tidal behavior, so use it as a guide for timing, not as an exact schedule.
Spring and neap tides
Tidal range is usually larger near new and full moons (spring tides) and smaller near the quarter moons (neap tides). Bigger swings mean stronger current, which can help or hinder depending on your spot. In heavy flow, fish may hold behind structure and in eddies. You can read more in how the moon affects fishing.
Other factors that change the picture
- Time of day. A good tide at midday may be less productive than a so-so tide at dawn.
- Wind. Strong wind can add to or fight tidal flow and change water clarity.
- Weather and pressure. Some guides suggest fishing high-pressure periods before an approaching front on a rising tide may help. Treat this as a tendency, not a rule.
- Species and season. The same tide might suit one fish and not another.
- Location. A flat, a jetty and an inlet each fish differently on the same tide.
FAQ
What’s the best time to fish the tides? Usually when water is moving, a couple of hours either side of slack, with exact timing depending on your location.
What is the rule of 12 for tides? An approximation of how tidal flow changes hour by hour, explained above.
What is the 50-90 rule for tides? I have not found a reliable, standard definition for this phrase, so I would not rely on it. If you see it used, check the source before planning around it.
What attracts fish the most? Food and suitable cover. Tides matter mostly because they move food. For finding productive spots more generally, see how to know where fish are.
