Météo/Marée

Bassin Arcachon Info can not under any circumstances be held responsible for the weather information available on this page.

For the sea : PM means Pleine Mer (deep sea), BM means Basse Mer (low sea).

On the Arcachon Basin, we have two particular phenomena that distinguish the basin’s weather from the general regime..

Indeed the huge volume of water that enters the bay and comes out with the tide induces circulations of marine currents and temperature variations that have a great influence on cloudiness. The best proof is that during the tide, sunshine, winds and cloud cover will change. This is especially sensitive if the weather is relatively calm.

Second particularity the dune of Pilat. This huge volume of sand is a singularity of the Landais coastline, its nature (unwooded) creates at the entrance to the basin of particular hot air ascents and therefore on the basin of the most intense thermals.

In general, these two particularities mean that the Arcachon Basin local weather is very advantageous compared to the general weather in the region.
