Traveller notes on Hossegor in August

Notes from nearby Bilbao (134 km away)

Hossegor doesn't have its own notes for August yet — these are about Bilbao, close enough to share the season.

Regulars call this normally the driest month of the year here on paper, warm and agreeable in the mid-to-late 20s Celsius, while being honest that the Atlantic coast setting means rain can still arrive any time regardless of the seasonal odds. Our row backs that warm, genuinely humid read, 27.4C reading as a hot 29C, over 16.9C nights, with 54mm of rain across 7.5 days and humidity at 80 percent. Regulars are consistent that a rain layer belongs in the bag even on what looks like a reliably warm week, since the region's unpredictability doesn't fully disappear even in its best month. The sea sits at a swimmable 22.9C, a real highlight for anyone splitting time with San Sebastian's beaches. The record: 11.1 hours of sun, a 15.8 kph wind and AQI 41.

Other months in Hossegor

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.
