Storm Glass

API

Global marine weather data aggregated from multiple reliable sources

Overview

Storm Glass offers RESTful access to global marine weather data compiled from 10+ trusted sources (e.g., NOAA, ECMWF). Key endpoints include /weather (waves, wind, sea temp, precipitation), /tide (tidal predictions), and /astronomy (sun/moon phases). Responses are JSON-formatted, with filters for location (lat/lon), time range, and data sources. Ideal for surf forecasting apps, marine navigation tools, fishing planners, or coastal event organizers needing accurate, multi-source marine weather insights.

Example Integration (JavaScript)

script.js JS


fetch('https://stormglass.io/')
  .then(res => res.json())
  .then(data => console.log(data))
  .catch(err => console.error(err));
