Conditions at Shivas in December
December: Consistency and Christmas Clean-Ups at Shivas
December is arguably the most consistent month of the year. Average swell height hangs around 0.8m (2-3ft) with a 10.0s average period, and ideal surfing conditions top the annual chart at 61%. The swell direction is more mixed than November - SSW (16.4%), SW (11.3%), WNW (10.9%), NW (12.1%), W (9.6%) and WSW (8.9%) - but no single direction dominates, and the SW/W windows still provide plenty of options for this beach. The wind is the real story: strong ENE (16.1%) and E (13.4%) flows, along with significant NNE/NE contributions, create the offshore, slightly side-offshore texture that keeps the surface clean and contestable. Rainfall is very low at 0.26 mm/day, air temperature averages 25.9°C, and water temperature is 28.5°C. Expect fun, rippable 2-3ft waves with a decent chance of a longer-period swell pulse in the days after Christmas.
