Kayaking and Paddleboarding: Reading Tides and Currents

Tide doesn't just change water depth — on many coastal routes it creates current strong enough to make or break a paddling trip. Here's how to plan around it.

Tidal current, not just tide height

In channels, inlets, and river mouths, a rising or falling tide pushes a lot of water through a relatively narrow gap, creating current that can run faster than most paddlers can comfortably fight. Even calm-looking water can be moving several knots on a strong tide. Check current predictions for your route, not just tide height, if you're near an inlet or narrows.

Plan to paddle with the tide, not against it

A simple strategy for a there-and-back trip: paddle out against the tide while you're fresh, and return with the current pushing you home. Timing a one-way trip to start near slack water and ride the building current in your direction of travel can turn a hard paddle into an easy one.

Slack water is your friend for exposed crossings

For open crossings or launching from a tricky spot, the slack water period around high or low tide — when current is weakest — is generally the safest and most predictable time to go. Bigger tide swings mean shorter, more pronounced slack windows and stronger current the rest of the time.

Watch for exposed flats and changing depth

On shallow bays and marsh systems, a falling tide can strand a kayak or paddleboard on mud well before you'd expect, and a rising tide can quickly cover launch points or sandbars you were standing on. Know the tide chart for your put-in and take-out, not just the open water.
