Conditions at Airport in December
December: Wet Season Reboot
December marks the return of the northwest monsoon, and the wind numbers tell the story. W is the dominant wind at 33.7%, WSW adds 16.8%, WNW 10.7%, and the ideal-wind score plummets to 23%. For a west-facing beach these are directly onshore directions, and they make even a solid 5ft (1.6m) average swell look messy. Ironically, the swell direction is one of the best of the year: SSW (57.0%), SW (36.5%) and WSW (3.6%) put a lot of west into the wave angle, and the 12.7s period still carries punch. If the wind unexpectedly swings to E/ESE, often overnight, the surf can be surprisingly good.
Wet-season weather returns with 8.14mm/day of rain, air temperatures average 25.8°C, and water is a warm 29.3°C. December is about waiting for the windows. When the offshore flow shows up, the west-angled swell makes Airport hollow and fast; when the monsoon is blowing, the bumpy surface keeps most surfers on the sand.
