May: The Peak of Power and Purity
May is the month when Capao da Canoa really turns on. The average swell is around 5-6ft (1.5-1.8m), the average period jumps to 9.8s -- the highest of the year -- and the swell direction rotates further clockwise, with S becoming the dominant source at 18.1 percent and SSE close behind at 16.7 percent. This is full-on late-autumn groundswell generated by intense cyclones in the South Atlantic and frontal passages over the Rio de la Plata region. The 5-6.5ft and 6.5-8ft bands make up a significant share of the wave energy.
Equally important, the wind machine flips in your favour. The ideal wind statistic peaks at 33 percent, with WSW and SW combined contributing 20.8 percent and W adding another 8.3 percent. That means more clean, groomed surf on the ESE-facing beach. The trade-off is the cooling ocean -- water temperature drops to 20.0°C and air temperatures average 16.6°C (ranging from 4.1°C to 28.7°C). Still, if you want powerful, long-period swell with offshore texture, May is hard to beat.
