Data sources

The forecast, the hour-by-hour temperature and the humidity of your plans and rides come from Open-Meteo.

We average the route's points and the ride's hours, correct the temperature for altitude and, for a ride more than 14 days away, use the mean of the last 5 years.

Next to every weather figure: “Weather: Open-Meteo”, linked to its website and to this page.

For a ride more than 14 days away there is no forecast: we use the mean of that same day over the last 5 years, hour by hour. We also read from the archive the weather of a ride or a sweat test more than 5 days old. Open-Meteo's archive combines the ERA5 reanalysis of the Copernicus Climate Change Service (C3S) and ECMWF's IFS model.

The maps use OpenStreetMap data, under the Open Database License (ODbL), and the names of the climbs come from OpenStreetMap too. We draw the maps with Protomaps from our own servers. Protomaps
