Met Office Blended Probabilistic Forecast for 7,213 UK and European Sites

Percentile weather forecasts for 7,213 specific sites across the United Kingdom, Ireland, and parts of Western Europe. The data is produced by the Met Office's IMPROVER Blended Probabilistic Forecast system, which blends and calibrates operational Numerical Weather Prediction ensembles and nowcasts. This information was correct as of April 2026, though details like the number of sites may change.

Use Cases
