Conditions at Yin Yang in January
January: Classic East-Swell Windslop
The northeast monsoon is running on all cylinders in January. ENE swell accounts for 40.2% of the spectrum, with another 28.4% from the E and 10.6% from the ESE - exactly the directions that light up Yin Yang - and the average 1.1m (3.6ft) means plenty of 3-5ft (1-1.5m) lines moving through the atoll. The catch is the wind. NNE (21.6%) and NE (31.3%) blow steadily from the sea, creating cross-onshore chop over the reef; ENE also sneaks in at 18%. With an average period of only 6.4s, the surf is punchy but disorganised. When a rare NW/NNW offshore pulse aligns with the E/ENE swell, Yin Yang can turn on for a few hours, but the 17% ideal-wind figure says it all: pick your windows. Air temperatures sit near 27.3°C, water temperature is 28.5°C and daily rainfall averages 2.9mm.
