Conditions at Karmay in December
December: Big Swell, Short Days, Winter Commitment
December delivers some of the biggest surf of the year. Average height is 7.5ft (2.3m) and period 9.4s, with the wave rose dominated by W, WNW and NW plus healthy WSW and SW contributions. The North Atlantic storm track is wide open, and Karmay can see repeated pulses of 6-10ft (1.8-3m) surf when a deep low parks southwest of Norway.
The catch, as always, is wind. SE and SSE combine for over 23% of the wind rose, bringing cross-shore/onshore conditions, while ideal offshore N through E flow occurs 24% of the time. Short daylight, average air temps of 5.5°C and falling water temperature at 8.0°C make sessions a hardcore commitment. Still, if you time it right, December is arguably Karmay's finest month for pure power.
