Precipitation: Weekly mean anomalies
Base Time: Sat 04 Oct 2025 00 UTC T+216 Valid time: Mon 06 Oct 2025 00 UTC - Mon 13 Oct 2025 00 UTC
Weekly mean anomalies have been calculated relative to a 20-year model climatology. The areas where the ensemble forecast is not significantly different from the climatology, according to a WMW-test, are blanked.
Note that shaded areas are at 10%, contours are at 1% significant level.

Forecast charts and data
We provide current forecasts, climate reanalyses and specific datasets. These are available via the web, point-to-point dissemination, data servers and broadcasting.
Forecasts, analyses, climate reanalyses, re-forecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.
Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various licence agreement types.
Serving meteorology
International collaboration is fundamental to the work of ECMWF, working with the EU and the meteorological community at large, including the World Meteorological Organization, space agencies, and scientists around the world.
