Conditions at Sosua in May
May: Small, Clean and Trade-Wind Dominated
May is the true start of the low season. Average swell height settles at 3.9ft (1.2m), period drops to 8.1s, and the N/NNE/NNW window collapses to just 7% of the wave rose. Instead, ENE and E swells combine for over 70% of the energy, and this directional shift means limited exposure for Sosua's north-facing sand. The saving grace is wind: 46% of observations are considered ideal, with ESE/SE trades often blowing cross-offshore and keeping the surface glassy. Expect mostly waist-high, 2-4ft (0.6-1.2m) waves that are cleanest at dawn. Water temp climbs to 26.9°C, air averages 26.2°C, and rain increases to 2.5mm/day. It is still fun for logging waves, but real power will be hard to find.
