About Tide Chart USA

Tide Chart USA turns NOAA's tide predictions into fast, readable pages for every US tide station: a chart for today, the week ahead, a month table, sunrise and sunset, and the best daylight low tides.

The predictions come from the NOAA Center for Operational Oceanographic Products and Services (CO-OPS). We download them every night, so each page always shows the next month. Sunrise, sunset and moon phase are calculated from each station's position.

We are not affiliated with NOAA. Predictions are not observations, and this site is not for navigation.
