Conditions at Warner Beach in December

December: High Summer, Short Periods, Warm Water

December is the heart of the summer surf season, which in statistical terms is the low-quality window for Warner Beach. The average wave height remains 5ft (1.6m), but the average wave period is the shortest of the year at 8.7s. The swell direction is dominated by SSE 20%, E 19%, SE 17%, S 16%, ESE 15% and ENE 12%. A lot of this is locally generated windswell from the E/SE trade-wind belt and passing coastal lows rather than organised groundswell.

Offshore conditions are rare: ideal wind registers just 21%, while NE/ENE trades and SSE/S/SSW winds dominate. The summer sea breeze and thunderstorms regularly put a fresh bump on the surface. Water temperature warms to 23.8°C, air temps average 20.8°C, and rainfall is the highest of the year at 7.26mm/day. For the holiday surfer, there are still plenty of 3-5ft (1-1.5m) waves, but the best plan is to chase a dawn glass-off and embrace the warm-water summer slop.
