Conditions at Bico in October
October: The North Atlantic Roars Back
The North Atlantic roars to life during October, and Bico feels it immediately. Average swell height jumps to 1.5m (around 5ft) and the period lengthens to 11.3s. Swell direction is a balanced mix of NW (35%) and WNW (33%), with W (13%) adding plenty of opportunity for west-northwest groundswell to unload on the sandbar.
Wind conditions improve dramatically: 28% of the time the wind is ideal, with offshore easterly/southeasterly flow becoming more frequent as high pressure builds over the continent. The persistent summertime NNW wind drops to 22%. Air temps cool to 18.3°C, water still holds at 18.2°C, and rain increases to 2.49 mm/day as storms refill the North Atlantic storm track. October is a window of opportunity: the ocean has winter power, but the water is still warm enough for a lighter wetsuit.
