Conditions at Byberg in April
April: Clean, Fun-Size Shoulder Surf
April sees the swell engine ease off. The average wave height drops to 3ft (0.9m) and period to 7.5s, which is enough for a grovelly but rideable wave. The swell window is still strongly NW: NW accounts for 22.0% and WNW 16.0%, while W adds another 13.2%. Combined favorable directions reach 55.7%, yet much of that energy is lower-quality windswell rather than long-period groundswell.
Winds become more of a problem. The offshore quadrant is only about 31% of observations, ideal wind 12%, while NNW winds spike to 21.3% and NW adds another 9.2%, creating frequent onshore chop. However, the air is starting to warm (5.5°C) and the water is up to 6.2°C, with precipitation at its annual low of 3.08mm/day. The smart play is to chase east wind days under high pressure, when those fun-size NW pulses become clean, playful beach peaks.
