December: The Calm Before the Storm Season
December settles into early summer doldrums. The average swell height is just 1.2m (4ft), and the average period drops to 11.1 seconds, meaning less organized, more wind-affected wave patterns. SSW and SW swells still dominate the direction rose at 33.7% and 42.2%, with S swell adding 8.6%, but the size distribution is concentrated in the 1-1.5m and 0.5-1m range. This is a fun-sized, groveling pattern rather than a powerful groundswell regime.
Ideal offshore conditions fall to 27%, with E through S onshore winds becoming increasingly common. SE and SSE each blow about 12% of the time, S adds 9.0% and ESE adds 7.4%, making the afternoons lumpy. Water temperature warms to 16.8°C, air temperatures average 16.2°C, and rainfall remains low at 1.76 mm/day. December is a month for chasing dawn sessions, fun 2-4ft (0.6-1.2m) waves, and waiting for the first big autumn swells to return.
