Tides API
High and low tide predictions for thousands of US coastal stations, powered by NOAA CO-OPS. Search the station directory by state or name, pull full station metadata (coordinates and time zone), and get tide predictions as high/low events or an hourly height series for up to seven days, in feet or metres and against the datum of your choice (MLLW, MSL, MHHW and more). Delivered through a fast, reliable API with clear errors for invalid stations. Ideal for boating and sailing, fishing and surfing, ports and logistics, beach and tourism services and coastal planning.
