December: The Summer Reset
December marks the start of official summer and a slight reset in size - the annual average dips to 6.2ft (1.9m) and the period to 12.4s, the shortest of the year. That is still a very solid, long-period surf for La Rinconada. The swell rose is dominated by SW and WSW, which together sit near 85%, with only a sliver of west/northwest energy; the result is more angled swell that relies on the cove's bathymetry to organize. Winds are excellent for the season: S/SSW/SW/WSW flow is the overwhelming regime, ideal wind sits at 47%, and the usual summer dry pattern means just 0.47mm/day of rain. Air temperatures reach 14.2°C and water temperatures are 12.9°C. Bigger and more direct winter swells have faded for now, but clean, fun-size surf and the best beach weather of the year create a worthy summer peak.
