Kvassheim - surf spot statistics

Kvassheim, Norway, is exposed to consistent swell year-round, but the best surfing conditions typically occur between November and March when ground swell contributions are highest (19-28%) and mean swell sizes range from 1.9 to 2.2 meters. Winter months see the most favorable swell composition, with ground swells providing cleaner, more organized waves, though wind conditions remain challenging with bad winds (onshore/cross-shore) dominating 85-89% of the time. February stands out with 28% ground swell and 2.0-meter waves, though winds are still unfavorable 85% of the time. Spring and summer (April-August) bring smaller waves (1.0-1.2 meters) and reduced ground swell influence (4-22%), making conditions weaker and less reliable. September and October offer a transitional period with improving swell size (1.4-1.8 meters) but still suffer from poor wind consistency. Overall, dedicated surfers will find the best waves in winter despite frequent bad winds, while summer provides smaller, windswell-dominated waves with marginally better (but still poor) wind conditions. For optimal sessions, target the coldest months and prepare for strong winds—patience and thick wetsuits are key.

June at Kvassheim offers relatively mild surf conditions with an average swell height of 1.0m and a moderate period of 7.0s, indicating mostly small, manageable waves. The predominant swell directions are from the NW and W, with the highest wave energy occurring in the 0.5-1.5m range. The SW and SSW directions also contribute decent swell, but larger waves (over 1.5m) are less frequent, making it a spot better suited for intermediate surfers or those looking for relaxed sessions. Wind conditions are often the limiting factor, with only 14% of winds being ideal (light offshore or sideshore). The NW and NNW winds, which are common, tend to be stronger (20-50kph), creating choppy or cross-shore conditions. However, lighter winds (below 20kph) from the W or SW can provide cleaner waves. Overall, June is not the most consistent month for surfing here, but there are rideable days, especially when wind and swell directions align—typically with smaller, cleaner waves rather than powerful surf. Patience and flexibility with timing will be key.
