October: The Roar Returns
October is a standout month in the Alvor surf calendar. The average swell height climbs to 1.1m (3.5ft) and the period jumps to 11.1s as the North Atlantic storm track becomes more active. The wave rose broadens and becomes more mixed: WNW 28.9 percent, NW 28.3 percent, W 14.7 percent, WSW 6.7 percent, and SW 3.1 percent, with direct S/SSW/SW contributions now combining for a meaningful share of the total energy. Ideal wind reaches 40 percent - one of the best monthly percentages of the year - as NNW 20.0 percent and NNE 4.5 percent, along with N and NE flow, groom the incoming groundswell. Water remains warm at 19.2°C, air averages 19.4°C, and precipitation jumps to 2.23mm/day. This is the classic month when warm water, building S/SW swell, and autumn north winds align to deliver Alvor's best wave quality of the year. The North Atlantic is roaring to life, and the sandbars feel it.
