Conditions at Vanimo in December
December: Peak Season Prize
December delivers Vanimo's most consistent surf of the year. The average swell height sits at 1.2m (4ft) with an average period of 10.6s, and ideal surfing winds reach 58%, tied for the highest of the year. NNE accounts for 54.6% of all swell, N adds 21%, and a healthy 19.3% comes from NNW, making the most of the beach's NNE exposure. There are also increasing amounts of 1.5-2m (5-6.5ft) sets from the N-NNW window.
The wind regime features plenty of light W, WNW and NW monsoon flow, but the high ideal-wind percentage points to frequent offshore and semi-offshore conditions from the S-SSW-SW-WSW quadrant. Water temperature holds at a warm 29.4°C, air temps average 27.5°C, and the build toward a classic tropical Christmas swell is well underway.
