Conditions at Vanimo in May
May: Trade Winds Take the Wheel
May marks a clear shift to trade-wind swell. The average height falls to 0.8m (2.5ft), and the average period compresses to 8.9s, so waves become funkier and less powerful. Swell direction flips toward the east, with NE contributing 51.7%, NNE 26% and ENE 10.2%. Nearly all of this energy sits in the 0.5-1m (2-3ft) range, making it longboard and funboard territory.
E, ESE and SE winds are common as the southeast trades deepen, but ideal wind still sits at 53%, keeping plenty of workable windows on offer. Water temperature climbs to 29.6°C, and rainfall drops to 5.57mm/day, giving drier, sunnier days between the trade breeze.
