Soaringmeteo - Meteorology for soaring pilots


Welcome to the Soaringmeteo main page

Have a look at our free weather models to predict thermal soaring flight conditions (e.g. for paragliders, sailplane and hangliders). There are two forecast types:

There are also many original documents to understand the weather conditions and the use of the tools in this website. The concept of convective boundary layer, also called diurnal planetary boundary layer is extensively used (often not taught in pilot training courses).

New version of Soaringmeteo available for testing

We are currently working on a new version of Soaringmeteo, which should be easier to maintain and evolve. It does not yet support all the features of the current version of Soaringmeteo, but it provides a higher resolution for long term GFS forecasts. This new version will be progressively improved until it includes all the current features.

We encourage you to try it here: You can also follow and contribute to its development here:


Temporary fallback to OSM map background

Due to the fire which impacted an OVH datacenter, we have to switch back to the standard OpenStreetMap tiles. The Soaringmeteo map background will be back in a few days.


New map background

In order to move away from GoogleMaps we have designed a new map design based on OpenStreetMap data. When finalized, the map design will be opensourced.

Retrospective 2017

Your donations helped to pay for the costs of running the servers, it is appreciated!

Although most of the changes on 2017 has no visible effect, a major effort went into reinstalling servers, improving source quality and use of a version control system, etc. This changes make the long term stability better and improve the capactity to make controlled updates.
