General information

AccuWeather's Tidal Forecast API delivers tide predictions — high and low tide times and water levels — for coastal locations worldwide. Useful for boating apps, fishing planners, beach-condition dashboards, and marine logistics.

Forecasts are available in more than 200 languages and dialects.

→ See the Tidal Forecast Guide and Parameters for endpoint details and request patterns.

Forecast windows

Tidal forecasts are available for 1, 5, 10, 15, 25, and 45 days ahead.

Station metadata

The API also returns metadata for the underlying tidal station that provides each forecast — useful for displaying station names, locations, and reliability information alongside the predictions.

Requirements

Tidal Forecast searches require a LocationKey. Use the Locations API to look one up.
