October: The Roar Returns
The North Atlantic roars back to life in October, and Biarritz is front and center. Average swell height climbs to 4ft (1.3m) with period 11.3s. The swell window is split almost evenly between WNW (41.2 percent) and NW (42.1 percent), with NNW adding 4.8 percent. The distribution now features a substantial middle: 3-5ft (1-1.5m) at 27.7 percent, 5-6.5ft (1.5-2m) at 18.3 percent, 6.5-8ft (2-2.5m) at 7.6 percent, and the first waves over 8ft (2.5m) starting to show. Long-period, organized lines are becoming the norm again.
The wind becomes much more favourable: ideal for surfing 42 percent of the time. S winds (10.5 percent), SSW (6.3 percent), SW (5.3 percent) and WSW (5.9 percent) combine with light variable periods to deliver many glassy sessions. W (10.5 percent) is still a threat, but the balance is shifting. Water temp remains pleasant at 18.4°C, air at 15.2°C. October is arguably the best blend of size, frequency and thinning crowds.
