Free · In‑App Purchases · Designed for iPhone. Not verified for macOS.
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
• 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
