Conditions at Baltrum in April
April: Lighter Sideshore Winds and a Grooming North Sea
Spring has officially sprung, and the North Sea's energy begins to wind down. The average swell height drops noticeably to 1.0m (3.3ft), a direct response to the weakening Atlantic storm track. The dominant swell direction is overwhelmingly NNW, which accounts for a huge 21.7% of the wave spectrum - a perfect fit for Baltrum's exposed, north-facing beach. The periods sit at 6.1s, meaning the waves are often crumbly and soft, but they are plentiful. The wind roses reveal an increase in ENE-E directions (a combined 16.3%), which are offshore enough to groom the waves when the swell direction aligns. The 'ideal' wind frequency is 11%, and with water temp at a brisk 7.8°C and air temps reaching up to 23°C, you can finally ditch the thickest wetsuit. It's not a month for huge barrels, but it's the start of a fun, groveling season. Look for days where a NNE wind blows against the NNW swell - it will hold the wave faces open for a clean, rippable, if not overly powerful, session.
