Conditions at Sandvik in April
April: Spring Lull With Better Cleanliness
April sees the average swell height ease to about 5-6ft (1.7m) and the period shorten to 9.8s-a step down from winter, but still average-to-punchy and perfectly rideable. The swell window remains dominated by SW (17.9%), SSW (12.6%), WSW (11.6%) and S (10.1%), although the size classes skew smaller than in January. The key change is wind quality: ideal offshore conditions climb to 14% of the time, and there are more light NNE/N winds than midwinter. Precipitation eases to 3.26mm/day, air temperature rises to 3.4°C on average, and water temperature edges up to 6.1°C. This is a great month for avoiding the harsh winter while still scoring head-high-plus waves, especially when a late-season cyclone passes by and leaves NE wind in its wake.
