December: Early Summer Trade-Wind Pulse
December brings back the summer pattern. Average swell height eases to 5ft (1.5m) and period drops to 8.4s, while ideal wind sits at 36%. The trade winds are in full control, with ENE (18.1%), E (19.1%), ESE (17.4%), SE (13.3%) and SSE (12.0%) providing a near-constant supply of easterly swell. The 4-5ft (1-1.5m) class is the most frequent, so expect fun-sized, rippable waves rather than heavy winter bombs. There is still a sprinkling of 5-6.5ft (1.5-2m) peaks from the ESE-SSE directions, so the occasional bigger set will show up.
Winds are mostly from the northeastern quadrant - NNE (20.7%) and NE (21.2%) - creating side-shore, sometimes bumpy texture throughout the day. SSW (8.8%) and SW (6.3%) may clean things up in the afternoon, but true offshore conditions are limited. Summer is settling in: air temperature averages 23.6°C, water temperature climbs to 23.5°C, and rain returns at 4.11mm/day. December is a good month for longboarders, beginners and anyone happy to trade power for warm-water fun.
