Conditions at Kuta Reef in December
December: Monsoon Returns
December signals the return of the northwest monsoon. Ideal offshore wind plummets to 24%, and W (33.7%), WSW (16.8%) and WNW (10.7%) winds take control, producing onshore and cross-onshore texture on the west-north-west-facing reef. The underlying swell is not bad - average 1.6m (5-6ft), period 12.7s, from SSW (57.0%) and SW (36.5%) - so the Indian Ocean is still sending pulses. But windswell mixed on top of the groundswell, plus 8.14mm/day of rain, often masks the quality. Air temps stay warm at 25.8°C, and water temps peak at 29.3°C. For dedicated surfers, the play is clear: wait for a dry burst of E/ESE/SE wind behind a passing system, then pick off the best of the SSW/SW groundswell before the next monsoon squall.
