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.

November at Kvassheim offers surfable conditions, though they can be challenging. The average swell height is 1.9m with a decent period of 8.7s, providing enough energy for intermediate to advanced surfers. The dominant swell directions are from the SSW, SW, and WSW, contributing to the most consistent waves, with the highest frequency in the 1.5-2.5m range. However, clean conditions are relatively rare, with only 13% of days having ideal offshore winds (typically from the NE to E quadrant). Most wind directions are onshore (SSE to WSW) or sideshore, often blowing in the 10-30kph range, which can create choppy or messy waves. Stronger winds (over 30kph) are common, particularly from the SE to SSW, further reducing surf quality. Larger swells (over 2.5m) occur occasionally but are offset by less favorable winds. In summary, November delivers sizeable waves but requires patience for those clean, rideable days. Watch for NE wind shifts for the best sessions.
