December: The Pick of the Season
December takes the crown as the most consistent month for surfing at La Chiesa. The average swell reaches its annual maximum of 1.0m (3.3ft) and the period is the longest of the year at 5.8s. Better yet, the ideal wind percentage peaks at 29%, with NNW (13.5%), N (5.0%), and NW (5.4%) accounting for a combined 24% of all surface winds. The southern half of the swell compass is still very much alive - SE (9.8%), SSE (7.8%), S (7.6%), SSW (6.5%) - but even the W/WSW quadrant (16.2% and 11.4%) can produce rideable waves when the wind is offshore. Water is 16.1°C and air averages 12.0°C, so pull out the hooded wetsuit. Rain is significant (3.33 mm/day), but the clearer, post-front days are where La Chiesa shines: crisp, lined-up peaks on a small, clean south swell with offshore north wind.
