Conditions at Costa da Caparica in October
October: The North Atlantic Roars Back to Life
October is the true transition into prime surf season. Average swell height jumps to 1.5m (5ft) and periods reach 11.3 seconds, fueled by a climatological increase in strong extratropical storms across the North Atlantic. The swell distribution spreads nicely along the western quadrant: NW 35%, WNW 33%, W 13%, WSW 4% and SW 2%. That is a much healthier mix for Costa da Caparica's WSW-facing sandbars than the summer NW slabs. Ideal wind windows return to 41%, with light-to-moderate offshore E/NE winds still present early in the day. The weather becomes more dynamic too-air averages 18.3°C, water remains warm at 18.4°C, and rainfall increases to 2.49 mm/day as the first autumn fronts sweep through. October is when the extended forecast starts to matter again. When the right combination emerges, you get long-period swell, sunny skies and light winds-that is when the great waves really come to life.
