Coastal Tide PlannerWhen can I get out and get back?

Pick your days — not your way through a tide table

⚠ Planning aid only — not for navigation. These are NOAA tide predictions. Wind, barometric pressure, and other factors can move real water a foot or more off the table. The chart uses tide predictions, not predictions of water depth or navigation hazards at any particular point. Local knowledge and experience should always take precedent. This app just narrows the calendar for planning purposes.
What is this app for?

Coastal Tide Planner answers one question: which days of a month could I actually get out and get back?

Most tide apps hand you a chart and leave the arithmetic to you. This one works the other way round. You tell it four things: roughly when you'd like to leave, how long you want to be on the water, how long after the first low tide your departure route has enough water, and how long before the next low tide your return route has enough water. It reads the NOAA tide predictions for the station you choose, then grades every day of the month and shows you the ones worth taking off work for.

The part only you can supply is the water at your own spot. NOAA knows the tide; it does not know the bar at the mouth of your creek, or how much water your boat needs. The departure time you set after the first low tide and the return time you set before the second low tide are where your own experience counts, and they are what turn a tide table into a plan.

Designed to cover the 3,499 NOAA tide stations in the United States.

📍 Choose your tide station
Choose the station closest to where you launch and/or where you plan to boat or fish.
R stations publish the full tide curve. S stations publish highs and lows only, so levels between tides are estimated.

And stay out about this long
1h 10h 4h
Drag the slider to set how many hours you want on the water. Days are then graded on how close to your chosen time the water actually lets you go. If nothing within three hours of it works, the day is marked Not good.
Your water — this is where your own experience matters
Leave minutes after low tide
Return minutes before the next low tide
My area runs minutes earlier / later than the tide station
Because tides vary the further you are from the tide station, choose a time adjustment based on your experience for the area.
