Conditions at Biarritz in May
May: The Shoulder-Season Lull
May confirms the seasonal slowdown. Average swell height falls to 3ft (1.0m) and period to 10.1s. The direction is still remarkably good - NW at 50.1 percent, WNW at 40.8 percent and NNW at 5.7 percent - but the surf is increasingly marginal. The largest share of the swell sits in the 2-3ft (0.5-1m) groveler range, and only a small percentage reaches 5-6.5ft (1.5-2m).
The wind is ideal just 23 percent of the time. WNW (16.0 percent), W (13.6 percent), NW (13.5 percent) and NNW (12.9 percent) dominate, though wind speeds are low, so the ocean is often clean. It is a month for high-performance boards on small waves, or for chasing the occasional late-spring low pressure system that slips further south. Water temp climbs to 16.6°C and air to 15.3°C - spring wetsuit territory.
