May: High Pressure and Long-Period Ground Swell
May signals the true onset of the best surf season. Ideal wind spikes to 37%, with 31.1% of all winds blowing from the western quadrants (W, WSW, WNW, NW). The average wave period reaches 9.7s - the year's peak - and swell height is a solid 1.8m (5.9ft). Though the swell direction shifts somewhat south (S and SSE combine for 31%), the long period and offshore winds transform even average-sized waves into powerful, clean walls at Tramandao. Morning offshore sessions are frequent, and the water is still a reasonable 19.9°C. Air temps drop to 18.7°C on average, with rainfall around 3.90 mm/day.
