December: Back to the Summer Grind
December brings the return of full summer conditions. The ENE trade wind dominates at 26.9%, with NE at 18.8%, leaving ideal wind at just 18%. Swell height eases to 1.6m (5.2ft) and the period drops to 8.2s, so waves are more windswell-like. The direction mix is actually favorable - ENE and E combine for 43.1% of the swell - but it is often accompanied by onshore breeze. Persistent sea surface warmth of 22.4°C and air temps of 22.4°C make it a great beach day, but surfers will have to pick their windows carefully.
