Conditions at La Source in October
October: Autumn Swell Season Fires Up
The North Atlantic roars back to life in October and the numbers at La Source show it: average swell height jumps to around 6ft (1.8m) and the average period lengthens to a solid 11.6s. The swell direction shifts west again, with NW at 30.4%, NNW at 53.1%, WNW at 3.7%, and W at 0.6%; the longer period means more of this energy arrives with real push. Winds are ideal for surfing 59% of the time, and the E/NE offshore flow becomes more reliable, setting up long, clean waves under late-summer warmth. Water temperature is 18.9°C, air temps are 15-31°C, and precipitation is 0.60mm/day. This is the sweet spot between solid swell and pleasant conditions.
