December: Monsoon Size and the Onshore Trade-Off
December signals the start of the best surf window in terms of size and period. Average height climbs to 4ft (1.2m) and the period runs 10.5 seconds, the longest of the year. NNE swell again dominates at 51 percent, NE at 23 percent, NNW at 11.5 percent, and N at 11.5 percent, with NW contributing 2.3 percent. A healthy share of the swell reaches the 3-5ft (1-1.5m) range, and the 1.5-2m (5-6.5ft) category gets a few more entries, especially from NNE and NNW. The wind, however, is the classic monsoon downside: W 16 percent, WNW 15 percent, WSW 13 percent, and NW 11 percent, leaving ideal offshore conditions at just 25 percent. December is rich in tropical showers, with 7.06mm/day of rain, air temp 28.4°C, and water temp 30.0°C. To score, you need an early-morning offshore gap or a lucky east-southeast wind day between monsoon pulses.
