Conditions at Almagreira in October
October: The Atlantic Awakens
October is when Almagreira really comes back to life. The average swell height jumps to 7ft (2.1m) and the period to 11.4s, as the North Atlantic storm track begins to intensify. The swell is beautifully directed: NW 27.1%, NNW 18.1%, and WNW 17.4%, with very little southern or easterly energy in the mix. This is prime NW groundswell season, and the beach starts seeing consistent, powerful, rippable surf in the 5-8ft (1.5-2.5m) range.
The wind is also more cooperative than in summer. Ideal offshore flow from S through WSW rises to 23%, and although NNW winds still appear 17.8% of the time, the days with a clean southerly component often deliver everything Almagreira has to offer. Water temps remain warm at 18.3°C, air temp averages 17.7°C, and rainfall begins to increase again with 2.87 mm/day - a sign of unsettled, synoptically active weather.
