Untick a model to leave it out of every cell. The number is how many days ahead that model reaches here. All "seamless" models blend in that agency's regional high-resolution model where one exists. (Australia's BoM ACCESS-G is not listed: Open-Meteo has published no data for it recently.) Which of them has been most accurate here?
Tick a column to show it. Drag the handle, or use the arrows, to change the order. Two neighbouring columns that share an hourly value (High + Low, Wind + Wind avg) merge into one cell in the hour rows.
About Weather Models
- What do the three numbers in a cell mean?
- The lowest, the mean (or the median, switchable in the toolbar) and the highest forecast across the weather models that are switched on. Purple outer numbers mean the models disagree by more than usual for that column. The big number is tinted by its value: blue for cold or wet, orange and red for hot, strong wind or high UV; ordinary values stay plain.
- Which weather models are compared?
- Nine global models, fetched through Open-Meteo: ECMWF IFS, ECMWF AIFS (AI), NOAA GFS, DWD ICON, Met Office UKMO, Météo-France ARPEGE, ECCC GEM, JMA and CMA GRAPES. The "seamless" variants blend in each agency's regional high-resolution model where one exists, so the same list works anywhere in the world.
- What do the small arrows mean?
- On most number columns an arrow shows that the models' average for that day has moved since their run three days ago, using Open-Meteo's archive of previous runs: by at least 1° for temperatures and dew point, 1 mm of rain, 1 cm of snow, 5 km/h of wind (4 for the day's average, 8 for gusts), 15% cloud, 8% humidity, 3 hPa of pressure or an hour of sunshine. Chance and UV have no arrow because the archive does not keep them. Hover or tap the cell for the change.
- Is anything tracked or uploaded?
- Nothing is tracked: no cookies, no accounts, no analytics. Two things do leave your browser, both over HTTPS: the coordinates of the place you choose go to Open-Meteo to fetch the forecasts, and the text you type in the search box (or your position, if you press "Find me") goes to Photon to look the place up.
