June to August is Biarritz's best weather and its high season together. July averages near 24°C, and the sea is warm enough that the forum says you can often surf in shorts by mid-month, with some days not needing a wetsuit at all — they put the water at 20–21°C, the record a little higher. The honest caveat is that the weather is temperamental: a couple of really nice days, then rain, then a couple more, with afternoon thunderstorms in the mix, against seven wet days on the record. The rocky coastline is the surf advantage here — the breaks vary with the wind, so something is usually working.

Hossegor-forum posts from regulars living in town describe September and October as arguably the best stretch of the year: the summer crowds and novice surf-camp swarms have thinned out, water is still warm enough for boardshorts most days, and swell size starts climbing from summer's smaller waves toward the bigger, more consistent conditions the Landes coast is known for. Mornings typically run glassy with light offshore wind, occasionally turning onshore by afternoon, though posters say it often holds offshore the whole day on a good stretch. The daytime temperature sits in a genuinely comfortable range for a full day at the beach, but regulars flag a sharp drop once the sun goes down - evenings call for a jacket even after a warm afternoon. The record: 24.6C days feeling like a mild-for-the-season temperature, 16C nights, 103mm across 12 days, a 23.3C sea, 72 percent humidity and 10.1 hours of sun - the evening chill the forum describes shows clearly in that day-to-night spread.
