December: Festive Season Windslop
December rounds out the year with ideal winds at 39% and the average period still low at 7.5s. Swell size is around 3ft (1.0m), built mostly from E (28%), ENE (20%) and ESE (19%). Fresh, humid north-quarter winds are prominent: NNW 19%, NNE 10%, N 7% and NE 6%. That onshore flow is the enemy of the north-facing bank, shredding an otherwise rideable swell into bumps. Rain picks up to 4.42mm/day and water temp reaches 24.0C. Look for the post-frontal southerly bursts and early-morning land-breeze windows - they can still turn December into a classic Gold Coast summer surf session.
