Conditions at Belharra in May
May: Small but Countless
May officially ushers in the low-energy season. Average swell height is 4ft (1.2m), average period is 9.9s, and ideal wind only 23% of the time. Directional consistency remains stunning - NW 50.9%, WNW 28%, and NNW 13.2% account for 92% of the wave energy - but it is mostly sub-5ft (sub-1.5m) stuff, with the largest chunk (19%) in the 2-3ft (0.5-1m) class. The good side: there is almost always some swell running along the Landes and Basque coasts. The bad side: winds are now predominantly from W/NW/NNW, blowing straight onshore at Belharra. Air temps are mild at 15.1°C, water temps 16.3°C, and rain is relatively low. For an XL session, forget it this month. For fun small waves on a shortboard, the surrounding beachbreaks are a better bet than the reef.
