December: Peak Season Resurrected
December delivers the goods. Ideal wind jumps to 60%, average swell is 5-6ft (1.5-1.8m) at 12.7s, and the direction is classic Nusa Dua: SSW 57.0%, SW 36.5%, with a touch of WSW 3.6%. The wind rose flips back to a dominant W (33.7%) and WSW (16.8%) flow, with WNW (10.7%) and NW (2.7%) reinforcing offshore/cross-offshore grooming. This combination - powerful 12-13s SSW/SW lines and cleaner, offshore-groomed surfaces - is what makes December the start of the prime window. Water temp warms to 29.3°C, air sits at 27.9°C, and tropical rainfall returns (7.6mm/day). If you're planning a trip to Nusa Dua, this is the opening act of the best season.
