Biarritz is in southwestern France, just 11 miles north of the Spanish border, along the Atlantic coast's Bay of Biscay. The ocean's influence tempers the weather year-round, with summers on the warm side and winters a bit chillier, though rarely truly cold. Temperatures seldom drop below the 60s.
Spring and fall are generally the high tourist seasons here, with visitation to Biarritz peaking from May through June and then again from September through October.
The mercury rises considerably in the summer, with averages in July between 68 and 80 degrees. That’s still pleasant beach weather, so a summer vacation here works well for those needing a seaside retreat during July and August. And if you're drawn to Biarritz for the waves, time your visit during the Biarritz Surf Festival, held each July.
Winters on the whole are dry and sunny, though not necessarily warm. Average temperatures in January range between 39 and 51 degrees.
