Conditions at Trigg Point in December
December: Summer Pattern, Dawn Patrol Only
December locks in the summer regime: hot days, early offshore breezes, and a southwesterly seabreeze that shuts the beach down by midday. The average swell height holds around 6ft (1.9m) with an 11.7s period, so there are still fun, rippable waves from the SSW/SW quadrant - SSW delivers 28.8% of the energy and SW 48.1%, with a touch more SSE/S swell in the mix. Ideal offshore wind is at its annual low of 24%, and SSW wind dominates at 25.4%, making dawn patrol essential. Water temp climbs back to 20.9°C, air temps reach 21.3°C, and rainfall drops to 0.34mm/day - the driest month of the year. When the morning E/ESE breeze lines up with a long-period SW groundswell, Trigg still offers clean, playful waves. Just be out of the water before the seabreeze turns it to chop.
