Conditions at Five Islands in December
December: The NE Monsoon Arrives
December locks in the northeast monsoon and restores the classic Five Islands formula. Average swell height drops to about 4ft (1.2m) with a 9.4s period, and the wave rose becomes nicely mixed: SE 19%, SSE 19%, S 14%, ESE 12%, SSW 10% and SW 9%. The return of E/ESE/SE swell brings the wave angles back into the sweet spot for the southeast-facing reefs, with most waves in the fun, rippable 1-1.5m range and a scattering of 1.5-2m sets. Ideal offshore wind is back up to 53%, with a well-balanced flow of W 13%, WNW 14.6%, NW 12.1% and NNW 12.2% providing plenty of grooming. Rainfall eases to 5.56mm/day, air temperature is 27.2°C and water temperature is 28.7°C. The reefs start to fire on a regular basis, making December the natural kickoff to the peak season.
