Le Bourget-du-Lac (French pronunciation: [lə buʁʒɛ dy lak], literally Le Bourget of the Lake or Arpitan: Le Borgèt-du-Lèc[1]) is a commune in the Savoie department in the Auvergne-Rhône-Alpes region in eastern/south-eastern France.

It lies near the Lac du Bourget and 12 km (7.5 mi) from Chambéry.

Climate

Le Bourget-du-Lac is right on the boundary between a mid-latitude, four seasons humid subtropical climate (Cfa) and an oceanic climate (Cfb) under the Köppen system. In spite of this, it is highly influenced by its interior position within France, near several mountain ranges, resulting in quite hot summers and winters with frequent temperatures below freezing, especially at night. Convective rainfall is frequent for much of the year, rendering high precipitation/day quotas. The nearest weather station is located at Chambéry Airport, 3 km east of the town.
