October: Prime Swell, Warm Water
October is the click point where Isla de Santa Marina really turns on. Average swell height jumps to 1.6m (5ft) and period lengthens to 11.3 seconds, bringing back proper long-period power. The direction is superb: NW at 50 percent, WNW at 17 percent, and NNW at 14 percent. The North Atlantic low-pressure train re-establishes itself through the autumn, and with the sea still holding 18.4°C water, October can deliver both quality and comfort.
Ideal wind stays at a strong 48 percent. The wind rose shows a mix of light S/SSW flow and stronger W/WNW winds, meaning the best sessions often come in the days immediately after a cold front passes, when winds swing offshore and the swell is still pulsing. Rain increases to 3.1mm/day as storms cross the region. This is a prime month: solid NW groundswell, a warm ocean and frequent clean windows.
