Conditions at Kuta Beach in December
December: The Wet Season Battle
December closes the year the way it opened - with the northwest monsoon pushing onshore wind across Kuta. Average swell height is 5ft (1.6m) and period is a respectable 12.7s, so the raw energy is not missing. Swell direction remains favorable with SSW at 57.0%, SW at 36.5%, and WSW at 3.6%, but the wind is the great equalizer. W winds dominate at 33.7%, WSW adds 16.8%, and WNW adds 10.7%, leaving only 22% ideal wind. Rainfall jumps to 8.14mm/day and water temp is warm at 29.3°C. The best chance for a clean wave is early morning when a land breeze can overcome the westerly flow. When those windows line up with a good SW swell, Kuta can still dish out powerful, rewarding sessions amid the wet-season chaos.
