Conditions at Kvassheim in May
May: Spring Lull and Small Windows
May starts to feel like summer at Kvassheim, for better and for worse. Average swell height drops to around 3-4ft (1.1m) and average period falls to 7.2s, so the ocean increasingly becomes local windswell rather than deep-ocean groundswell. The swell rose still shows a strong NW component at 25.3% and a healthy S/SSW/SW/WSW component near 24%, but many of those S/SW waves are short-period and soft. Offshore wind percentages ease to 23% and NW/NNW flows are common, especially after frontal passages. With air temperatures now averaging 8.9°C and reaching a max of 21.4°C, water at 9.0°C, and precipitation at 2.55 mm/day, you can start to drop a wetsuit layer. Surf quality is very inconsistent, but the persistent NW background swell means there is almost always something to paddle for on the right sandbars.
