Did you ever wonder what the weather was like on the day you were born? This new app can be your time machine to revisit past weather.

Weather Replay from copernicusecmwf enables anyone to revisit the weather anywhere on the globe, hour by hour, from January 1940 up to a few days before present.

The simulations uses ERA5 reanalysis, a cloud-ready ARCO archive system produced with roughly the same tools used for the ECMWF weather forecast.

The app allows users to select a date and location and features a selection of significant historical weather events like storms, heatwaves, and flooding. Weather Replay can also compare two events. For example, the heatwave in Scandinavia in July 2018 with the unprecedented heatwave in Fennoscandia of 2025 which was featured as a highlight in the European State of the Climate #ESOTC2025 report.

Explore this app through the link in our bio.
