November: Storm Season Ramps Up
November delivers serious surf. Average swell height climbs to around 7ft (2.1m) and period jumps to 12.0s, with an even better blend of directions: NW at 28.9%, WNW at 15.6%, NNW at 14.9%, plus W at 5.2% and WSW at 2.2%. That southwesterly component is gold for Martinhal because it aligns directly with the optimal swell window. The wind pattern becomes more mixed in the autumn transition: NNW is 22.3%, N/NNE accounts for 16.7%, and there is a distinct rise in SE/SSE winds that can bring onshore lumps between fronts. Rain increases markedly to 2.95mm/day, air temps fall to 16.7°C, and the water is still pleasant at 17.9°C. November is for storm-watchers: pick the post-frontal windows with NNW/NW offshore flow and you will find some of the most powerful waves of the year.
