Conditions at Scar Reef in December
December: The Monsoon Takes Over
December marks the official start of the low season at Scar Reef. Ideal wind falls off a cliff to 48 percent, and the wind field becomes a messy mix of SW (17.3%), SSW (16.6%), WSW (12.6%), NNE (9.3%) and W (5.3%). Much of this is cross-shore or onshore for a NW-facing reef, so quality suffers. The average swell is still 4ft (1.3m) with a respectable 12.8s period, but the dominant SSW (63.7%) and SW (35.9%) directions remain a poor match for the spot. Heavy rain returns at 7.56mm/day, with warm, sticky air at 26.9°C and water temperature 29.9°C. Surfable days exist only when the wind flips into the light S/SE quadrant; outside those windows, expect rained-out and bumpy conditions.
