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.

Hey folks, I built a little web app called SwimTemp for checking real sea temperatures before booking a beach trip.
My friend and I love water sports, and we always wanted to know if the ocean would actually be warm enough before committing to a vacation. Weather apps kept showing the wrong thing as they basically measure air temperature inland, not the actual sea. So I built something that uses real satellite data instead.
This is the first hobby project I have ever taken all the way to production (work projects definitely don't count 😄). That's also why I just registered on Reddit....wanted to share it with people who might actually find it useful.
Okay I know it sounds silly, but I kind of feel like I am introducing my ugly and also cutest puppy to everyone I bump on the street...
Anyway, it is completely free, no signup needed. You can click anywhere on the map to check ocean temperatures, or browse 50 popular beaches with monthly averages.
Would love feedback from fellow travelers, especially if you spot any beaches where the data seems off!

Hey folks, I just shipped a new feature: Wave Conditions 🌊
SwimTemp now shows real-time wave height, swell and ocean current data alongside sea temperature, powered by Open-Meteo's Marine API.
It tells you not just how warm the water is, but what state it's in:
🏄 Good surf conditions 🌊 Moderate waves 😊 Light waves: good for swimming 🏊 Calm: ideal for swimming
Useful for surfers, divers, open water swimmers, sailors and anyone who cares about what the ocean is actually doing before they get in.

Hi folks, it has been a week since we released the last version of SwimTemp, because the co-founders found the perfect spot using our own product and went on vacation in the Adriatic Sea for a week! The water was warm, calm, quiet and absolutely perfect for a hot summer swim.
Anyway, we are back and ready to keep making SwimTemp better.
Most products focus purely on functionality. We do too, but what makes us different is also the taste and the philosophy behind what we build. That is why one of the co-founder @jiao_wang2, the UX designer, has been at the wheel of this ship from day one. Because we believe how something feels is just as important as what it does.
Check out the newly released version at https://swimtemp.com/ . Small changes but Real difference.
