GFS forecast for London

Loading model forecasts…

Daily values: maximum temperature, total precipitation (including showers and snow water equivalent), maximum wind speed. Dates use the selected city’s time zone. Missing or incomplete days show —; shorter models are never extended.

The min–max band covers available models (other models on individual pages); it is not a confidence interval. “Models disagree” means a daily spread of at least 5°C, 10 mm precipitation or 15 km/h wind, with at least two models. These are comparison guides, not official warnings.

About the GFS forecast

GFS is produced by NOAA / NCEP. The solid line is this model alone; the dashed line is the median of the other available models at the same time. It never includes GFS itself. Counts can fall as shorter forecasts end.

Resolution and update cycle

  • GFS · NOAA / NCEP · about 13 km · scheduled every 6 hours (00, 06, 12, 18 UTC). Feed details.

Hourly points may be interpolated from coarser model steps; grid spacing does not mean street-level accuracy.
