Conditions at Vanimo in April
April: Small but Clean Transition
April is the classic shoulder month at Vanimo. Average swell height eases to 0.9m (3ft) and the period drops to 9.7s, meaning the surf becomes smaller and more average in shape. NNE still leads at 48%, with NE jumping to 29.8%, but most of that energy is in the 0.5-1m (2-3ft) range. There are still some 1-1.5m (3-5ft) pulses, especially from NNE, but consistency is lower.
Despite the smaller waves, April's ideal wind percentage is among the highest of the year at 58%, making it one of the cleanest months to ride smaller, user-friendly waves. The trades are starting to build from E and ESE, yet plenty of light S-SSW-SW-WSW windows appear. Water temperature warms to 29.1°C, and rainfall drops slightly to 6.96mm/day.
