Conditions at Cova da Alfarroba in October
October: The Roar Returns
The North Atlantic roars to life during October and Cova da Alfarroba sees a sharp jump in average surf heights. The monthly mean steps up to 7ft (2.1m) with an average period of 11.4 seconds - that's proper long-period groundswell. The swell direction is more west-inflected than summer: NW (27%), NNW (18%), WNW (17%) and even a meaningful W (6%) component, all of which wrap nicely onto this north-facing coast. Wind is the big win: the percentage of ideal S/SSW/SW offshore flow jumps to 26%, tied for the best of the year, as autumn low pressures track closer to Iberia and bring more southerly pre-frontal winds. When the right combination emerges - long-period NW swell plus light southerly winds - the setup can be absolutely pumping. Air temps settle at 17.7°C, water at 18.3°C, a 3/2 wetsuit, and precipitation climbs to 2.87mm/day as the storm track becomes active.
