Conditions at Sele in December
December: Winter Sets the Standard
December delivers the best ratio of swell and clean wind that Sele offers all year. Average wave height is 1.5m (5ft), the period is 8.3s, and ideal wind conditions peak at 15%, the highest of any month. Swell directions are nearly perfect, with W at 13.0%, WNW at 12.6%, NW at 12.0%, WSW at 11.9% and SW at 9.8%. This sustained winter westerly pattern provides the beach with a steady diet of powerful, rideable groundswell and the occasional long-period pulse of 10-14s.
The wind rose still shows plenty of SE (11.5%) and NNW (11.4%), so it takes some careful forecasting to find the cleanest windows. But those offshore easterly days are more common in December than any other month, especially when a continental high settles over Scandinavia and drives east winds out of the fjords. Air temperatures average 3.3°C, sea temperatures drop to 7.9°C, and precipitation peaks at 6.69 mm/day. It may be dark, wet, and freezing, but December is the crown jewel of the Norwegian surf season, a month when Sele can genuinely fire.
