Get US tide predictions — high and low tide times and heights, or hourly / 6-minute water levels — for any of 3,000+ coastal prediction stations, or every station in a state, up to a year ahead. Uses the official NOAA CO-OPS API. Great for fishing and boating apps, marine logistics, coastal construction scheduling, travel sites and AI agents.
