## What is Sea Temperature?

How warm is the sea today? Sea Temperature shows the water temperature at beaches near you, and at any beach in the world you can name.

MEASURED, NOT GUESSED
Temperatures come from NOAA CoastWatch and NASA JPL satellite analysis — the same public data used in oceanographic research, updated every day.

WHAT YOU GET
• Sea temperature at the beaches closest to you
• Search thousands of beaches worldwide — works with no signal
• What the temperature actually means for swimming
• Wetsuit guidance for surfing and diving
• Save the beaches you swim at

HONEST ABOUT WHAT IT IS
Most apps in this category show you a number and leave it there. This one tells you where the number came from and how far offshore it was measured, because that matters: a satellite reports one value for a patch of sea a few kilometres across, and the shallow water you actually stand in can be two or three degrees warmer on a hot, still afternoon.

WHAT IT CANNOT DO
It cannot tell you whether the water is clean, whether there are jellyfish or currents, or whether it is safe to swim today. It does not forecast — every number is a measurement already taken, not a prediction. Always follow the flags and the lifeguards. Oceans and seas only; inland lakes are not covered.

PREMIUM
An optional subscription adds unlimited saved beaches, the last 7 days at every beach, and comparison with the same week last year. You can also unlock one beach's history by watching a short ad instead.
