Conditions at Cloud 9 in May
May: Clean Glass, Small Waves
May is the classic small-and-glassy crossover. The southwest monsoon is beginning to build, and ideal offshore and cross-offshore wind jumps to 32%. The swell, however, has faded: average height is 2-3ft (0.8m) with a period of 9.1s, and a full 55% of the swell table is ENE wave energy in the 2-3ft (0.5-1m) class. E and NE add another 28%, but very few sets push past 3ft. What Cloud 9 lacks in size, it makes up for in texture-the wind fields are lighter, the surface is often silky, and a longboard or groveler will get plenty of work. This is the month where you trade power for cleanliness. Expect air temperatures around 28.3°C, water at 29.4°C, and precipitation at a seasonal low of 4.9mm/day.
