December: The Monsoon Flip - Swell Yes, Wind No
December is the beginning of the northwest monsoon, and Turtles feels the full impact. The swell is still there and the direction is good: SSW (54.1), SW (18.0), S (20.0), and WSW (5.4) combine for a west-southwest friendly spectrum. Average height is 1.6m (5.2ft) with a 12.4s period, so there is plenty of groundswell to surf. But the wind is ideal only 36 percent of the time. WNW (18.7) and NW (16.7) flows, plus W (8.6), blow onshore and tear up the faces. The occasional ESE (10.0) and SE (11.8) days will still be good, but they are increasingly rare. Rain is heavy at 9.86 mm/day, air temp 27.1°C, water 28.9°C. If you are chasing clean waves, December is about picking the windows and managing the lump.
