Conditions at Hellesto in December
December: Dark, Cold, and Powerful
December ends the year the way the North Atlantic should: big, cold, and alive. Average swell heights sit around 5ft (1.5m) with an 8.3s period, and the swell rose is a beautifully balanced mix of WSW, W, WNW, and NW, each landing in the 12-13 percent range. Ideal offshore wind is at 15 percent, tied for the best of the year, with high pressure over Scandinavia and eastern Europe directing cold east-southeast winds offshore. The price of these perfect conditions is the Norwegian winter: water temp 7.9°C, air temp 3.3°C, short days, and 6.69 mm/day of rain/snow. But for the hardcore surfer, December offers the best chance to score powerful, hollow, freezing-cold waves in pristine offshore light. The North Atlantic is in full winter mode, and Hellesto is in its element.
