RainAtlas: A Next-Hour Rain Check

rainatlas.com Visit website

Editorial interest 77/100 Selection signal · not a rating of the site

A public rain-radar site showing next-hour rain estimates in 10-minute steps, with country pages and a JSON API.

Landing page captured for the 2026-10-31 issue.

For: People checking near-term rain; developers needing weather data
Worth noticing: The homepage says each country page identifies its data source, distinguishing radar-based results from forecast-based ones.

Field notes

The homepage says radar images are rebuilt every 10 minutes from open networks, naming EUMETNET OPERA, DWD and NOAA. Its method varies by coverage: it uses DWD radar forecasts in Germany and nearby areas, extrapolates recent rain movement elsewhere when radar forecasts are unavailable, and falls back to forecast data where open radar does not exist. The site also describes an API with a free key limited to 500 requests per day.
