Tides

NOAA predictions for 3,282 stations across the US and its territories, and 375 more places in Japan, France, New Zealand, Norway and Queensland, calculated on your iPhone and checked against each country’s official tables. Every high and low for the days ahead, the year at a glance, and charts you can scrub through.

Conditions

Wind, gusts, waves, air and water temperature, rain and currents, hour by hour, from the National Weather Service and MET Norway, with the Weather Service’s marine and coastal warnings.

Alerts

High and low tides, the water above or below a height you choose, sunrise and sunset, the moon, wind and waves, and a morning report with the day’s tides, light and weather.

Everywhere you look

Home Screen and Lock Screen widgets, a Live Activity on the Lock Screen and in the Dynamic Island, Control Center controls, Siri, and an Apple Watch app with complications.

Not for navigation. Waterline shows astronomical tide predictions, which don’t include storm surge or wind-driven changes in water level. Use official forecasts, charts and warnings for safety decisions.
