Conditions at Agua d'Alto in May
May: Shoulder Season Gold
May slips into spring/summer transition mode with 1.8m (6ft) of average swell and a 10.0s period. The height distribution is nicely spread through the 1-2.5m range, so there are still plenty of fun, rippable waves. Directionally, NNW remains the workhorse at 19.3%, followed by NW (13.4%) and WNW (8.9%). The ideal S-to-WSW window is still a small piece of the pie, but those southwestern pulses are becoming more frequent than they were in the summer months.
The bigger story is wind quality: ideal offshore N-to-ENE flow jumps to 36%, and the strongest wind directions (NNW 12.1%, NNE 8.4%) are mostly favorable for keeping the beach clean. This is the first month where you can start thinking about lighter wetsuits-water temperature reaches 17.5°C, air averages 17.2°C, and precipitation eases to 1.35 mm/day.
