SeaWindow: Tide Times & Charts

New: every hourly chart on the Forecast tab, a faster tide curve, and a map where any tide station opens with one tap.

Know the tide before you go.

See exactly when the water turns: the next high and low tide on a clear tide curve, with official NOAA predictions in the US and open tide-station data around the world. Check wind, gusts, waves and sea temperature for your stretch of coast at a glance, and plan the trip around the best bite window — from your iPhone, Lock Screen or Apple Watch.

TIDES YOU CAN READ IN A SECOND • Tide curve for today with the next high and low tide and the water level right now • High and low tide table, and yearly tide tables • Station, datum and local time shown with every prediction • Search any coast or use your location; SeaWindow picks the nearest tide station and shows how far away it is • Where no station is near, a clearly labelled estimate from a global tide model • Tides are calculated on your iPhone outside the US, so they work offline

MARINE WEATHER AND SEA CONDITIONS • Hourly wind, gusts, air temperature, pressure, humidity, visibility, UV, rain and cloud cover • Waves and swell where available, and today's sea temperature from NOAA satellite analysis • Every hourly chart on one tab: tide, wind, rain, pressure, humidity, visibility, UV, waves and swell • Charts that leave gaps where a source has no reading instead of inventing values

SUN, MOON AND FISHING TIMES • Sunrise, sunset, twilight and moon phase calculated on device • Solunar major and minor periods to plan your fishing • A catch journal with photo, species, weight, method, notes and conditions

RADAR, MAPS AND FAVORITES • NOAA/NWS weather radar with frame history for the US, Alaska, Hawaii and the Caribbean • Standard and satellite maps with nearby tide stations worldwide • Save your favorite beaches, piers and harbors

WIDGETS, LIVE ACTIVITIES AND APPLE WATCH • Home Screen and Lock Screen widgets, tide Live Activities and an Apple Watch app
