Biarritz seasonal overview
Best Surf Season (October - March)
The heart of winter brings the largest and most consistent swell to Biarritz. With average wave heights between 1.3m and 1.8m and periods averaging 11-13 seconds, the North Atlantic delivers powerful, long period groundswells from the NW and WNW quadrants. A higher frequency of southerly to southwesterly winds, driven by passing low pressure systems, provides clean offshore conditions over 40% of the time in most months. This is when Biarritz truly fires, with classic A-frame peaks and long walls stacking up perfectly on the sandbanks.
Fair Surf Season (April & September)
These shoulder months offer a mix of smaller but still rideable swell, averaging 1.1-1.2m with periods around 10-11 seconds. The transition between seasons means more variable wind patterns. While the chance of perfect offshore conditions is lower (around 29%), windows of Southerly winds often coincide with fun sized waves from the NW. It is an excellent time for intermediate surfers to score uncrowded peaks with a good chance of clean shape under sunny skies.
Low Surf Season (May - August)
Summer sees a dramatic drop in both swell energy and wind quality. Average wave heights hover around 0.9m with shorter periods of 9-10 seconds, dominated by local windswell and small NW background swell. The predominant winds shift onshore from the NW and NNW, ruining wave face quality. Ideal offshore winds from the south occur less than 20% of the time. While occasional small, fun-sized waves can be found for a longboard or fish, consistent quality surf is rare. It is a time for beach relaxation rather than chasing barrels.

Conditions at Biarritz in February
February: Consistent Winter Swell
February is almost a carbon copy of January, with average swell height staying at 1.8m and period just a hair shorter at 12.9s. The WNW (41.2%) and NW (33.5%) again provide the bulk of the energy, often in the 1-2.5m sweet spot – heavy and firing. Ideal wind conditions drop slightly to 44%, but still frequent with southerly and SSW winds making up a solid 16.5% of the total. The main difference is a slight increase in north-northwesterly onshore winds (5.2% NNW) compared to January. When a deep low swings by and the wind clocks around to the south, Biarritz serves up long, hollow waves that will test your reflexes. February is another top-tier month for consistent, high-quality surf.
