Conditions at Agua d'Alto in October
October: The North Atlantic Roars Back
October delivers the first true autumn jolt. Average swell jumps to 2.3m (7.5ft) and period stretches to 11.2s, putting Agua d'Alto back into powerful long-period territory. The most common wave heights are 1.5-2m and 2-2.5m, with overhead sets arriving on the better WNW/NW swells. The direction table is still dominated by NNW (22.1%) and NW (11.5%), but the WSW and SW directions are beginning to account for more of the total, and those are the angles that light up this SSW-facing sand.
The wind tradeoff returns with the storms: ideal offshore N-to-ENE flow drops to 28%, while SW, WSW and W winds increase through the passage of autumn lows. With water still warm at 21.3°C, air temperatures at 20.4°C and precipitation rising to 2.64 mm/day, this is the classic shoulder month-electric when it lines up, stormy when it doesn't.
