Conditions at Yin Yang in December
December: Good Swell Angles, Bad Wind Odds
December marks the return of the northeast monsoon and a frustrating flip in Yin Yang's luck. The swell direction is again excellent: E 23.1%, ESE 17.4%, ENE 15.2% and SE 9.4% combine for 65% of the spectrum, which is about as good as it gets for this ESE-facing reef. Average swell height is 1.0m (3.3ft), period is 6.4s, and there are plenty of fun-sized 3-5ft (1-1.5m) lines. The problem is wind. NE (14.6%), ENE (11.7%), NNE (10.0%) and E (6.1%) blow from the sea toward the land for much of the month, leaving the surface lumpy and onshore. Ideal wind only reaches 36%, so the sessions worth surfing are usually short windows of W/NW flow during passing weaker monsoon pulses. Patience is essential.
