Weather-model estimates at the stated altitude of each point, not measurements. Source: Open-Meteo, updated every hour.
Compare panoramas of the Lac du Bourget from Ontex, Chambotte and Grand Port, and check the measured lake level. The water temperature is not measured by any open source: the page says so rather than estimating it.
In short. This page shows views of the Lac du Bourget, the level measured at Aix-les-Bains (a Compagnie nationale du Rhône station, with its time) and the air weather. The water temperature is not shown: no open, dated and reusable measurement is available, and the air temperature cannot stand in for it.
No open, dated and reusable measurement of the Lac du Bourget water temperature is connected to this page. The lake’s managers publish its scientific monitoring as reports, and local probes exist without permission for reuse. To compare measurements, check where they were taken, their date and their depth; the air temperature cannot be used instead.
CISALB: Lac du Bourget monitoringThe Compagnie nationale du Rhône (CNR) station at Aix-les-Bains measures the height of the lake on a gauge. The data shown are raw and unvalidated, and the level in metres NGF (the French national levelling datum) is derived from the gauge zero published by the source.
Ontex and Chambotte offer panoramas from the heights. Grand Port gives another angle on the lake. Compare the views to check visibility, without inferring water quality or swimming conditions from them.
Aix-les-Bains webcamOn 7 October at 13:00, the Compagnie nationale du Rhône station at Aix-les-Bains read 1.10 m on the gauge, i.e. about 231.46 m above the French NGF datum according to the published gauge zero (raw, unvalidated data).
It is not shown: no open, dated and reusable measurement is connected to this page. Rather than estimate it or use the air temperature, the page says so.
No. The water temperature must come from a dedicated measurement; the air temperature cannot replace it.
No. Check local information on the beach, lifeguard cover and any restrictions.
The three views are from Ontex, Chambotte and Grand Port, provided by the Grand Lac / Skaping network.
Text of this page last revised on . This date says nothing about how recent the images or data are: the webcams are supplied by the credited operators and their timestamp shows when the image was taken; model forecasts and official reports are separate pieces of information, each with its own time. The forecast applies to the point and altitude shown in the weather block.
