Conditions at Biarritz in August
August: Still Small, But the Pulse Is Back
August is the warmest month and still very summer-like, but the ocean shows the first subtle signs of life. Average swell is 3ft (0.9m) at 9.4s. Direction is excellent - NW (66.8 percent), WNW (25.7 percent), NNW (6.6 percent) - and the distribution is a bit chunkier than July: 3-5ft (1-1.5m) accounts for around 24 percent, while 5-6.5ft (1.5-2m) pushes back up to about 6 percent.
The wind is ideal 18 percent of the time. NNW (18.8 percent), NW (16.5 percent), WNW (15.6 percent) and W (12.1 percent) still dominate the sea breeze pattern, but occasional tropical/subtropical swells from the mid-Atlantic can stir things up, especially late in the month. With water at 22.9°C and air at 21.6°C, August is peak summer comfort. Keep expectations low but not zero.
