Radar Precipitation Forecast API (Beta)
Powered by MeteoGroup

Overview

MeteoGroup’s Radar Precipitation Forecast API provides time series with short-term precipitation forecasts, based on radar data via https://precipitation-forecast.weather.mg/search. A forecast can be requested that is either representative of a specific location, or an area smaller than 40x40 km (via the bounding box).

The time series contains a data set, including the latest observed radar-derived precipitation intensity value combined with a 3-hourly forecast. The time series has a temporal resolution of between 5 and 15 minutes, depending on the temporal resolution of the original source data.
