Conditions at Sunrise in December
December: Summer Time Slop and Rippable Mornings Only
December is the lowest point of the year for consistent quality. Average swell height is 1.7m (5.6ft) and the period is the shortest of the year at 8.5s. The SSE (19.6%), S (15.9%), E (16.3%) and ESE (12.4%) keep the beach receiving waves, but the short periods often produce weak, sectiony peaks unless a better-period S pulse squeaks through. Wind is the same summer story: NE 19.9%, ENE 13.4%, plus S 10.6% and SSW 17.9%, with true offshore W/NW flow at only 3%. The 'ideal wind' score is 15%. Water temperature is back up to 24.1°C, the air is warm at 23.3°C, and rain is frequent at 2.95mm/day. It's a month for fun-sized, groveling waves and early sessions before the trades come up. If you're flexible, save your trip for the winter months.
