December: Summer Returns With Cleaner Windows
December brings the ocean back to summer mode. The average swell drops to around 5ft (1.5m), the average period shortens to 8.2s, and the swell direction rotates back to ENE/E dominance. Those two directions combine for 44.9 percent of all wave energy, with ESE and SE still offering some background pulse. Expect fun-sized, rippable waves rather than heavy groundswell.
Wind patterns settle back into the NE/ENE trade regime. NE is the primary wind at 26.2 percent, ENE follows at 18.2 percent, and the offshore W/NW quadrant is only around 8 percent of the time. The ideal wind score is 18 percent, so most surf is a bit textural, but the warm water of 22.2°C and air temperatures averaging 21.3°C (ranging from 12.0°C to 33.5°C) make it enjoyable. Rainfall averages 4.13 mm/day. December is the last month of the low season before the autumn transition begins anew.
