SwimTemp uses real satellite data from Copernicus Marine, updated daily. Click anywhere on the ocean to check actual water temperature, or browse 50 popular beaches with live readings and monthly averages. Free, no signup. Built by a water sports enthusiast who got tired of showing up to beaches that were actually perfectly swimmable, despite what the weather app said.

Hi folks, people always say "live in the moment", but when it comes to planning a beach trip, you can't just wing it. The ocean doesn't care about your plans.

One sec you are happily riding your surfboard for the white wave, and before you know it, a pipeline comes out of nowhere.

Or you have booked a sailing trip, and on that morning... there's no wind...

Don't let these happen to you, and ruin your trip!

SwimTemp now has 3-day ocean forecasting. Real time forecasting. Takes 1 -3 second to run and make the prediction.
But it is all worthwhile!

🌡 Sea surface temperature
🌊 Swell height & period
💨 Ocean current
🌬 Wind speed & direction

Check before you go. Your future self will thank you.

Hey hunters,

Today we are launching Beaches Nearby, click anywhere on the map and discover real beaches within 50km, powered by OpenStreetMap. Each beach shows live water temperature and maps directly to a pin on the map so you always know where you are swimming. @jiao_wang2

Perfect for planning your next coastal trip, or just checking if the water is worth jumping in.
