Tides, Weather & Ocean API from TidesAtlas provides global tidal, weather, wave, swell, sea temperature, sun, and moon data for developers through a set of 12 REST endpoints. The service covers over 18,229 tide stations across 188 countries and is designed to support a wide range of marine and coastal applications, from navigation and fishing to research and real estate analysis.
The API offers both station-based and coordinate-based predictions. For a given port or set of coordinates, it returns high and low tide times along with their heights, using smart routing to select the most accurate data source. If a calibrated station is within 50 kilometers, the system uses that station’s prediction; otherwise, it relies on the FES2022 global ocean model to provide results at the exact coordinates specified. The API supports real-time data, including live observations for French ports where REFMAR/SHOM gauges are merged with predictions. For stations in France, responses include tidal coefficients based on the French scale, providing additional context for maritime activities in that region.
9% uptime. The service is suitable for a variety of use cases, including marine navigation, fishing applications, surf and water sports planning, coastal real estate assessments, scientific research, and integration into weather and travel dashboards. The platform is built on models including TICON-4, NOAA, and FES2022, and is intended to be accessible to both hobbyists and enterprise users.
Access to the API requires an API key, and new users receive 50 free credits upon sign-up. The documentation and endpoints are designed to be straightforward, with no reliance on XML or SOAP protocols. This makes it a flexible tool for integrating global marine and weather data into a wide array of digital products and services.
Tides, Weather & Ocean API sits in PulseGate's API design, testing & docs category. It focuses on accessing accurate global tides, weather, and ocean data for integration into marine and weather applications. It is built as a B2B product for developers of marine and weather apps. A free plan is available; paid tiers begin at $9. It runs on the web, the command line, and API.
Behind Tides, Weather & Ocean API is TidesAtlas, and the product first shipped in 2026. Development happens publicly on GitHub with 1 commits in the last 90 days. PulseGate's similarity index finds few close equivalents — Tides, Weather & Ocean API occupies a relatively distinct niche. Key capabilities include tide data, weather data, and ocean data. The interface is available in 5 languages, including English, Spanish, and French. It exposes integrations via a public API.
