Conditions at Les Cavaliers in October
October: The North Atlantic Wakes Up
The North Atlantic roars to life in October, and Les Cavaliers feels it along the west-northwest coast. Average swell rises to 1.3m (4-5ft) and period jumps to 11.3s, with W/NW directions evenly balanced: WNW 41.2%, NW 42.1%. The wave-height distribution now includes healthy doses of 1-1.5m (3-5ft), 1.5-2m (5-6ft), and even 2-2.5m (6-8ft) energy. This is real groundswell - the kind that wraps into the beach with push and shape. Offshore winds also become more common, with ideal conditions 41% of the time, thanks to the strengthening thermal contrast and early-season high pressure. E/ESE/SE/SSE flow totals about 28%, while onshore W-NW winds are less frequent, sitting near 31%. Water temp is a pleasant 18.5°C, and air temps average 15.2°C. As the first strong extratropical lows - and occasionally remnant tropical cyclones - march across the Atlantic, October delivers some of the best fall surf of the year.
