May: Trade Winds Tighten, Swell Starts to Fire
May signals the onset of the dry-season southeast trades. Ideal offshore wind drops to 12%, while ESE and SE directions combine for over 74% of the wind observations, many blowing 10-20kph. Meanwhile, the swell is on the rise: average height reaches around 5-6ft (1.7m) at a long 14.1 seconds, with S and SSW combining for over 85% of the wave energy. The bay sees increasing 6-8ft (1.8-2.4m) groundswell, but the trade wind puts more chop on the surface. May can still deliver if the wind eases overnight, but the quality downgrade is underway. Air temp is 27.1°C, water temp 29.0°C, and precipitation is low at 2.27mm/day.
