Conditions at Lista in December
December: Prime Time on Norway's Southwestern Edge
December is arguably the best month to score Lista, especially for surfers who thrive in cold, powerful conditions. Average swell height is 2.1m (7ft) with a period of 8.1s, and with a favorable NAO pattern, the Atlantic storm conveyor is aimed directly at northern Europe. The swell rose still shows plenty of W/NW energy, but a strong SW/WSW component is present, including a meaningful share of 2-2.5m-plus waves that can make Lista heavy and powerful. Wind offers the most promising percentages of the year: offshore N to ENE flow is 11% of the time, tied with February for the highest winter window. This often occurs as high pressure builds over Scandinavia after a cold front, sending crisp NE winds over the SW-facing beach. Onshore S-SW winds remain a factor, and precipitation averages 5.5mm per day. Water temperatures hover at 7.5°C while air averages 4.4°C. When it all lines up, December delivers the sort of grinding, powerful North Sea surf that Lista is known for.
