#forecast

Global river-discharge and flood forecasting as an API, powered by the GloFAS (Global Flood Awareness System) model via Open-Meteo. For any coordinate on Earth, get a daily river-discharge forecast of up to 30 days — with the ensemble spread (mean, max and min across forecast members) so you can gauge uncertainty — plus up to 90 days of recent discharge history, and a quick current-situation summary with today's discharge and a 7-day outlook (peak day, max/min and rising/falling/stable trend). Discharge is reported in cubic metres per second. Ideal for flood early-warning and monitoring, insurance and reinsurance risk, agriculture and irrigation planning, hydropower, and environmental research. Data covers modelled rivers worldwide (none over open ocean). Open data via Open-Meteo / GloFAS.
