May: The South Atlantic Roars to Life
May marks the official opening of Arpoador's best stretch. The average swell rises to 1.5m (5ft), the average period hits 11.0s, and S-direction swell accounts for 36.5% of all energy. SSE adds another 25%, SSW another 9%, and the presence of 2-2.5m (6-8ft) pulses from the S/SSW quadrant becomes a regular feature. At the same time, ideal offshore/cross-offshore wind blows 54% of the time, and water temps are still a workable 23.2°C. The combination of long-period south groundswell and clean North/NE wind regimes makes May one of the finest months for serious surfing at Arpoador.
