Conditions at Spiekeroog in April
April: Grovel Season Arrives
April marks the true taper of winter surf energy. Average wave heights drop to about 3ft (1.0m) and the average period falls to 5.8s, so Spiekeroog is increasingly reliant on choppy local windswell. The good news is that the swell direction is actually excellent: NNW accounts for 19.0% of the wave energy and NW another 16.6%, meaning the north-facing beach is often in the direct line of fire. The bad news is size, with the majority of those NW/NNW pulses sitting in the 0.5-1m (1-3ft) range. Wind is the main obstacle. NNW winds are the most common wind direction at 10.6%, and persistent spring onshore flow can kill quality. Still, about 11% of the time the wind goes offshore from the SSE/S/SSW/SW sector, producing clean if small, fun-sized and groveling 1-3ft (0.5-1m) waves. Air temps have climbed to around 7.4°C and water temp sits at 7.9°C; it is no longer survival conditions, but a full wetsuit is still essential.
