Geography
La Teste-de-Buch is located in the department of Gironde, in the middle of the Landes forest, and south of Arcachon Bay. It is the capital of the Pays de Buch. Neighbouring communes are Gujan-Mestras to the east, Arcachon to the northwest, and Biscarosse and Sanguinet to the south.
The Dune of Pilat is a famous landmark on the Atlantic coast, situated in the western corner of the commune. The seaside resort of Pyla-sur-Mer, the village of Cazaux, the bird refuge and sandbank of Arguin are also part of the town.
The Étang de Cazaux et de Sanguinet is in the southeast corner, astride the departments of Gironde and Landes. The rest of the commune area consists of old dunes, where the natural forest has changed little over centuries.
During World War I, an airfield was created near Cazaux for airplane pilots training (fighters and bombers). Most of the American volunteers pilots of the Lafayette Escadrille came to the "Camp de Cazaux" to finish their training as war pilots. When the U.S entered the war, the 36th Aero Squadron was based here.

La Teste-de-Buch features an oceanic climate (Cfb) under the Köppen system, closely bordering on a warm-summer mediterranean climate (Csb) due to the lack of rain in july compared to november, the wettest month of the year. Winters are cool and wet, while summers are hot but bearable. However, cold snaps in winter or heat spikes in summer are rare but not unknown.
