Conditions at Hornbaek in April
April: The Flat-Spot Transition
April is where Hornbaek's winter window starts to close. Average wave height falls to just over 1ft (0.4m), average period drops to 3.5s, and ideal wind plummets to 1%. The swell rose is actually more northwesterly than winter - WNW 11.3%, NNW 9.7%, NW 8.0% - but the vast majority of these waves are under 0.5m and generated locally. The wind rose shows a mix of E/ESE/SE (7.7%, 9.2%, 7.3%) and W/NW winds, which can create glassy offshore mornings but very little rideable swell. With air temperatures averaging 6.6°C and water at 6.0°C, spring has not yet arrived in the sea. This is the month when a handful of clean, knee-to-waist-high NW windswell days can appear, but on average it is a marginal transition month. Keep expectations low and the session short.
