October: The Atlantic Resurrects
October is where the Portuguese surf season truly kicks into gear. The North Atlantic storm track ramps up, and the average wave height jumps to 6.5ft (2.0m) with a period of 11.4 seconds. The swell directions are textbook for Praia Grande: NW 30.6 percent, NNW 19.5 percent, WNW 18.6 percent, and W 6.7 percent. These are long-fetch, long-period swells generated by vigorous extratropical storms, and the beach's west-northwest exposure is right in the strike zone. Importantly, the wind becomes more surfable again. Ideal offshore flow reaches 18 percent, while the dominant NNW wind drops to 22.8 percent, with N at 9.8 percent and NNE at 8.4 percent. This creates far more opportunities for east/southeast offshore winds to groom the swell into clean, grinding lines. Air temperatures average 17.6°C (min 7.3°C, max 29.0°C), rainfall increases to 2.62 mm/day, and water temperature remains warm at 18.4°C. October can offer the best combination of solid late-year swell and still-pleasant conditions; when the sky clears after a low, it is magic.
