Plan your paddle around the current.
Ebb & Flood puts NOAA current and tide predictions on a map, then times each leg of your trip against them, so you know when to cross and when to wait.
What it does
Currents on the map
Arrows at every NOAA current station show direction and speed for any time you pick. Tap a station for the day's chart, with max flood, max ebb and slack.
A trip planner that knows the water
Drop your launch, rest stops and camp. Set your paddling speed and Ebb & Flood works out each leg: how long it takes with the current, and how far to angle into it to hold your line.
Watch your day play out
Press play to watch the currents change hour by hour and see your kayak move along the route, for one day or the whole trip.
Works where there's no signal

How close to NOAA?
In Washington waters, 133 of 191 current stations show NOAA's own prediction, unchanged. At the other 58, Ebb & Flood estimates speeds between NOAA's slack and max times. In testing against NOAA's full predictions, 97% of estimates came within 0.3 kn. See how we tested it.
NOAA predictions don't include wind, river runoff or air pressure, which can change real conditions a lot. Ebb & Flood is for planning, not navigation. Check conditions on the water and use your own judgment.
