Conditions at Macaronis in December
December: Holiday Rain and Westerly Windswell
December rounds out the year with the least favorable conditions. Average swell height is back to 4.3ft (1.3m), the period is down to 12.3s, and ideal wind is at its lowest, only 30%. The swell direction mix is still decent on paper: SSW (47%), SW (28%), WSW (12%) and S (11%), but the period and wind quality are the issues. NW (24%) and WNW (20%) winds dominate, along with NNW (14%) and W (9%), so the surface is frequently chopped or cross-textured at the exposed reef. There are occasional 5-6ft (1.5-2m) pulses from the WSW and W, but they often arrive with onshore wind. Water temp is 28.9°C, air averages 27.2°C, and rainfall remains high at 9.6mm/day. If you are in Indonesia over the holidays, position yourself for the rare east-wind windows and wait out the monsoon.
