Conditions at Refsnes in April
April: Smaller but Cleaner
April marks the true transition from winter power to spring conditions. Average swell height drops to 4-5ft (1.4m) and the period falls to 8.2s, while the ideal SSW-to-W swell window still produces about 27 percent of the wave data. The bigger signal, though, is the increasing dominance of NW, WNW and NNW swell, which together account for more than 40 percent of observations. For a west-southwest-facing beach, this means more crossed-up, less focused swell; you need a W/SW component and a period of at least 8s for the spot to really line up.
The wind stats are more encouraging. Ideal offshore conditions occur 20 percent of the time - the highest of any month - and high-pressure blocks over Scandinavia create more manageable mornings with light E/NE flow. Air temperatures climb to 5.6°C, water sits at 6.2°C and precipitation drops to 2.99 mm/day, making April one of the drier months. There are fewer big days than in winter, but when the swell angle cooperates, the quality-to-crowd ratio can be excellent.
