Conditions at K59 in December
December: Peak Offshore Reliability
December is the most consistent month of the year at K59. The average swell height is 1.0m (3.3ft) and the period is 12.2 seconds - not huge, but beautifully long for the size. Wind is the headline: ideal surf wind peaks at 70%, with NNE absolutely dominant at 31.5%, NNW at 11.4%, NE at 9.8% and N at 5.2%. That means day after day of clean, groomed, offshore lines on the south-facing beach. Swell-wise, SSW provides 63.4% and S 22.7%, with SW 5.5% in support; most energy comes in the 0.5-1m (1.6-3.3ft) and 1-1.5m (3.3-4.9ft) classes, perfect for logging quick, rippable waves on a longboard or a high-performance shortboard. Air temperatures average 26.1°C, water temperature is 28.4°C and precipitation is only 0.30mm per day. This is the reliable, high-quality window to plan a trip around.
