Conditions at Sylt in April
April: Cleaner Winds, Smaller Lines
April marks the true transition to spring. Average swell height falls to 3.3ft (1m), average period slides to 5.8 seconds, and the wave train becomes increasingly short-period and local. The swell rose is still dominated by NW (17.8%) and NNW (13.7%), with WNW (10.9%) and WSW (9.9%) also in the mix, but the height distribution clearly favours small waves: most readings fall into the 1.5-3.5ft (0.5-1m) class, with fun 3-5ft (1-1.5m) waves appearing far less often. On the plus side, offshore winds reach their seasonal peak: ENE-E-ESE-SE flow totals 25.9% of the time, and the westerly onshore quadrant drops to around 31%. That means April often offers cleaner conditions than the preceding winter months, albeit on smaller, grovelly surf. Water temperature reaches 7.0°C, air temperatures average 7.0°C, and with only 1.40 mm/day of precipitation, April is the driest month of the year. If you are happy on a fish or high-volume shortboard, the early-morning easterly sessions can be surprisingly fun.
