December: Offshore Wind Dominance and a Return to Mixed Swell
December marks the full return of the dry-season trade-wind regime. NNW wind blows 73% of the time, with N and NW adding another 16%, giving Playa Teta the highest percentage of offshore wind of the year at 74% ideal surfing conditions. The swell rose becomes a genuine split: northern N/NNE/NNW swells make up 38%, while the better S/SSW/SW/WSW window still holds about 48%. Heights nudge up slightly to an average of 2-3ft (0.7m), but the average period drops back to 8.9s, reflecting shorter-period trade-wind swell. In practice this means clean, glassy mornings with an inconsistent mix of small SSW groundswell and northern windswell running through the lineup. It is a beautiful month to be in the water, but still not a consistent big-wave month. Water temp is 28.2°C, air temps average 25.8°C, and rainfall drops to 3.45mm/day.
