About YepTidal

Tide charts and daylight low tides, by NOAA station. YepTidal lists the predicted high and low tides at NOAA tide stations on the US coast, with sunrise and sunset, a month of tides you can print, and a search for low tides that fall in daylight. No sign-up, no account.

Where the data comes from

Tide predictions come from NOAA's Center for Operational Oceanographic Products and Services (CO-OPS). They're predictions, not measured water levels or a forecast, and they aren't for navigation. Heights are in feet relative to mean lower low water (MLLW), and times are in each station's local time, including daylight saving time. Sunrise and sunset are calculated for each station's location.

The tide calendars, curves, and low-tide searches are calculated by YepTidal from NOAA's predictions. They aren't official NOAA products. Methods and sources explains how.
