December: Trade Winds and Mixed Swell
December brings the northeast monsoon into full swing at Finnimas. Ideal wind is high at 55%, with NE (16.7%), ENE (14.7%), NNE (9.8%), NNW (9.5%) and NW (8.2%) providing plenty of offshore and cross-offshore flow. The wind is not the issue - swell direction is. The wave rose is a messy mix: S (14.2%), SSW (11.9%), SW (11.5%), WSW (12.3%), ESE (10.3%), SE (10.2%), SSE (9.6%) and E (9.1%) all contribute. Only about 36% of the swell is in the ideal SE-SSW sector. Average height is 1.1m (3.6ft) with a modest 8.9s period, meaning the surf is often small and a bit crumbly, though the clean offshore winds make it extremely fun on a high-performance shortboard. Water temperature is 28.7°C, air temp 27.2°C, and precipitation is 5.81mm/day. December is a solid 'small-wave clean-fun' month, but don't expect any big swell.
