October: Atlantic Roar Returns
The North Atlantic roars to life during October and we see a sharp jump in average surf heights along the Portuguese coastline in response. Average swell height climbs to 2.0m (6.5ft) and period lengthens to 11.5s, driven by the first powerful extratropical cyclones of the season. NNW (35.4%) and NW (18.0%) are the primary swell directions, with WNW (4.6%) and W (2.0%) filling in; heights are heavily concentrated in the 1.5-2.5m (5-8ft) band. The wind regime shifts too - offshore easterly to southeasterly flow becomes more frequent (25% ideal), and the NE trade weakens. Early-season water is warm at 22.9°C, so you may only need a 3/2mm while the swell is already firing. This is the start of the prime window.
