December: Dry-Season Trades and Short-Period Windswell
December closes the year with a return to winter trade-wind patterns. The wave rose is dominated by ENE (40 percent) and NE (23 percent) swell, with only 12 percent coming from the preferred S/SSW/SW/WSW window. Average wave heights stay around 4ft (1.3m), but the average period drops to just 8.9s, so the surf is average, punchy, and often a bit messy. True S/SW groundswell is rare, and when it does show, it is usually short-lived.
Wind is once again the story: ENE at 62 percent and NE at 32 percent, blowing 20-40 kph for much of the month. The offshore direction is great, but the strength makes it hard to find calm, glassy conditions, and ideal surf manages only 7 percent. Dry-season weather returns with 0.21 mm/day of rain, air at 27.3°C, and water at 26.9°C. It is a reliable, photogenic coast, but December is best for traveling surfers chasing fewer crowds rather than chasing max size.
