Conditions at El Faro in December
December: Summer Shadow, Clean But Flat
December brings the official start of the austral summer and the low point for El Faro's swell window. The average swell height drops to 2.4m (7.9ft), the period dips to 11.9s, and the entire N/NNW window combines to just 0.6% (WNW 0.5%, NW 0.1%). Meanwhile, the wind is almost annoyingly perfect: S (36.5%) and SSW (37.8%) make up 74.3% of observations, and ideal conditions sit at 14%. You can have a glassy, sunny day with 14.6°C water and 14.9°C air, but the bay will be a shadow of its winter self-clean, small, and marginal. The South Pacific High has locked the storm track far to the south, so the surfable N/NW energy has virtually disappeared. Grab the summer board, enjoy the weather, and mark the calendar for the first autumn fronts of April.
