December: The Return of Clean, Rippable Surf
December brings the curtain back up on Playa Hermosa's best season. Average swell height is 1.0m (3-4ft) and the average period is 12.3s - a touch shorter than mid-year, but still solid groundswell. SSW is extremely dominant at 95 percent of the energy, with 49.3 percent of waves in the 1-1.5m range and 45.3 percent in the 0.5-1m range. More importantly, ideal wind jumps back to 25 percent as N, NNE and NE offshore flow strengthens during the early dry season. Rain drops to just 2.82mm/day, air temperatures average 25.6°C, and water temps hold at 28.1°C. December marks the return of clean, glassy morning surf: head-high peaks, offshore texture and that warm tropical water making it the perfect holiday-season surf destination.
