Conditions at Playa Madrono in May
May: Southern-Hemisphere Swell Takes Over
May signals the real arrival of the rainy season, but also the definitive peak of southern-hemisphere swell supply. An enormous 86 percent of the wave energy comes from the SSW, with an average period of 14.1s - the longest of the year. Average heights stay around 3-4ft (1.1m), but these are genuine long-period lines with plenty of hold and push.
The catch is wind. Ideal conditions fall to 53 percent, and SW/WSW winds become common, especially in the afternoons. Playa Madrono becomes more of a morning-break spot: offshore NNW/N winds in the early hours, lumpy onshore breezes later. Rain jumps to 9.57mm/day, air temperatures sit at 27.4°C, and the water warms to 28.4°C. Stay flexible and chase the clean windows.
