Stormglass.io is a global weather and marine-data API that provides high-resolution forecasts and historical datasets. It aggregates many meteorological institutions and AI models in one unified interface.

You can access a wide range of parameters including: air temperature, air pressure, humidity, wind speed/direction/gust, precipitation, cloud cover, solar radiance, UV index, and for marine use: wave height, wave direction, swell, currents, water temperature, ice cover/thickness, etc. read more in our docs: https://docs.stormglass.io/

Yes – stormglass.io supports global coverage, marine and terrestrial, and provides data for any location worldwide.

The stormglass.io API is a simple REST-based interface. You send latitude, longitude, and the weather parameters you need — and receive forecast or historical data in JSON format. Read more in the docs: https://docs.stormglass.io/

No installation is required. All data is retrieved directly through API requests, making it easy to integrate with your applications, dashboards, or backend systems.

Simply sign up at stormglass.io/register
and generate your API key from the user dashboard. This key is required for all API requests.

There’s a free tier (10 requests/day, all parameters, but no commercial use) and paid tiers (“Small”, “Medium”, “Large”, as well as larger plans. It is always free to sign up with us. Upgrades and additional plans are available when signed in to the stormglass.io dashboard. Get the current pricing details at https://stormglass.io/pricing/

Yes — for commercial use, you need to subscribe to a paid plan (Medium, Large or any of the plans above) which explicitly allow commercial usage.

stormglass.io aggregates data from multiple trusted providers such as ECMWF, NOAA, Metoffice UK, Met.no, DWD, FMI, and other national meteorological agencies.

stormglass.io sources data from the world’s most trusted meteorological institutions and AI models. Many customer testimonials emphasise high data quality and service responsiveness.

Forecasts are available up to 10 days into the future, with varying time resolutions depending on the data source.

stormglass.io delivers frequently updated forecast and observed data with low latency — close to real-time — though it’s not a true live-stream API.

Yes, stormglass.io offers access to historical datasets, enabling long-term analysis for research, machine learning, or performance comparisons. Read more at https://docs.stormglass.io/#/hindcast

Once you hit your plan’s request limit, the API will return a “Too Many Requests” response. You can wait until the next day or upgrade to a higher plan for more capacity.

Yes. Complete API documentation is available at https://docs.stormglass.io/. Paid plans include direct support.

Yes, you can specify individual sources (e.g., “metno”, “noaa”, “sg”) or combine multiple ones.

stormglass.io AI is an intelligent global grid that automatically chooses the best weather source depending on performance. Use the source “sg” in your API queries.
