Reliable site for the water temperature of the Lake of Geneva. Very prompt reaction when asking for additional information.

Super idea to know the water temperature - critical for winter swimmers - all delivered in a very user friendly way!

Very useful site if you swim in Lac Léman.

App doesn't follow best practice design. The only way to quit the app on smartphone is to do an equivalent to Win+D. No other app in the world do that. The best practice is to always let the menu bar on the bottom. I personally can't use it...

Thank you for keeping us update with the temperature of the lake! It's very useful info particularly for the winter swimmimg sessions

This is a great site for lake swimmers. Accurate and reliable, thanks for all your efforts in making it available, much appreciated

I use it every Saturday when I go into the Geneva lake, it's amazing !

Top info

Rely on this year round and especially in winter when swimming in the lake. Very user-friendly and nice graphics.

This is a great tool to know the temperature of the water in a number of places around the lake, not just the official ones which are not very numerous, and often in rivers feeding the lake. Very simple to use - scan the QR code to know the temperature. The trend is also useful to see. Thank you for providing this data in such an easily accessible form
