Conditions at La Source in June
June: The Calm Before Summer Windswell
Average swell height sits at around 5ft (1.6m) and the period falls to 8.4s, reflecting the seasonal collapse of the North Atlantic storm track. The swell is almost entirely NNW at 78.9%, with only 12.3% NW and a negligible W component, meaning La Source is working mostly on short-period, wind-formed swell rather than proper groundswell. Ideal wind comes in at 44%; the N and NNW winds are stronger and more persistent, but the early-morning NE/E offshore still offers clean, small waves. Water has warmed to 17.9°C, air temps reach 16-35°C, and rain is nearly absent at 0.10mm/day. This is a good month for beginners and longboarders, not for chasing heavy waves.
