Conditions at La Source in May
May: Smaller Swell and a Window for Clean Morning Waves
Swell averages drop further to around 6ft (1.8m) with an average period of only 9.4s, so the power fades and wave quality becomes more dependent on wind. The swell rose is extremely NNW-dominated at 62.9%, with NW at 19.3% and WNW at 3.5%; the favorable W/WSW quadrant is essentially empty. Ideal wind plummets to 42%, with weaker E/NE winds and increasing NW/NNW flow, making for a spot that can turn bumpy by afternoon. Water temperature is 17.4°C, air temps are 14-34°C, and rainfall drops to 0.28mm/day. If you time a dawn patrol with an offshore E wind, there are still rippable, fun-sized waves, but this is no longer a high-performance month.
