May: The Monsoon Flip
May is a true changing of the guard. The northeast monsoon disappears and the southwest monsoon begins to send stormy energy around the islands. Average swell height bottoms out at 2ft (0.7m) and period shortens to 6.5s. The swell direction now splits: NNE (27.5%) and NE (16.3%) fade, while SW (12.8%), WSW (12.5%), and SSW (4.2%) appear. The favorable W-NNW band totals 15.5% - actually higher than in the winter months - but the waves are small and mostly windswell. Winds become more southerly, with S (11.3%), SSW (9.9%) and SSE (7.2%) common, and the ideal wind window sits at 37%. The rainy season begins with 6.00mm/day, while air and water hit 28.2°C and 30.0°C. May is grovel territory; only the biggest west swells will make Star Tubes shine.
