Conditions at Santo Amaro in October
October: The North Atlantic Reawakens
The North Atlantic roars to life during October and the change at Santo Amaro is immediate. Average swell height climbs to 6ft (1.9m) and the period lengthens to 11.4 seconds as the first severe extratropical cyclones organize south of Iceland. The wave rose remains anchored in the WNW-NW sector, with NW at 34.0 percent, WNW at 21.1 percent, and NNW at 14.4 percent, but the distribution widens slightly to include more WSW and SW groundswell. Ideal wind frequency holds at a solid 51 percent, making this one of the best months for scoring quality waves with offshore flow. Air temperatures are still mild at 18.3°C, water warm at 18.4°C, and rainfall starts to pick up (2.49 mm/day). When a low-pressure system dips south over the Bay of Biscay, the resulting left-peeling sandbars can be world-class.
