Conditions at Sesimbra in October
October: The Atlantic Reawakens
The North Atlantic roars back to life this month. Average surf jumps to 5ft (1.5m), the period climbs to 11.3s, and the extratropical storm track powers up across the ocean. Swell direction is split between NW at 35% and WNW at 33%, with 12% more from the west. This is a massive upgrade in energy for Sesimbra. Ideal wind is 48%, driven largely by NNW, N and NE flow, while the onshore SSW/SW component increases to around 19% as lows approach from the southwest. Water temp is still warm at 18.2°C and air temps average 18°C, making for some of the most fun surf of the year. Rain increases to 2.5mm/day, so expect a few frontal passages that deliver both rain and swell.
