Conditions at Borkum in April
April: The North-Northwest Machine
April is the spring transition month. Average swell height drops to 2-3ft (0.6-0.9m) and average period to 6.1s, but the waverose is absolutely dominated by NNW swell at 26.5% - the single largest directional peak of the spring. Add NW at 13.2% and you have almost 40% of all swell arriving from the exposed north-northwest corridor. Most of this energy is small: 11.7% of all observations fall in the 0.5-1m range and only 1.0% exceeds 2m. The wind pattern is far more mixed, with a strong onshore component from NNW at 11.3%, NNE at 5.9% and NW at 7.2%. Ideal winds are only 8%. This is a month of fun-sized, grovelly waves on a good sandbar; the North Sea has not switched off, but it is starting to sleep. Water temperatures rise to 8.5°C and average air temperatures reach 8.2°C, making spring sessions a little more comfortable but still definitely neoprene-season.
