Tides from anywhere in the world
Predictions on any coast, calculated with reference oceanographic models and official data in the United States (NOAA). Look up a station once and it stays available offline.
Tides anywhere in the world, right in your pocket.
Tide height, water temperature and sea conditions at any point of coast on the planet. No accounts, no ads, and it works offline.

Your nearest station, automatically

Built with your privacy in mind
No accounts, no ads and no third-party analytics. Your exact location never leaves your device: only an approximate version is used when needed, and only to calculate the tide.
Where the data comes from
Predictions are computed with the FES2022 ocean model, harmonic analyses from real tide gauges (TICON-4, DGFI-TUM) and, in the United States, official NOAA data.
Accuracy is good on open coast and more limited in estuaries and rías. SimpleTides must not be used as a navigation instrument.
