Conditions at Neva Bay in May
May: Summer Sizing Takes Over
May signals the move toward smaller surf at Neva Bay. Average swell height drops to 5.6ft (1.7m), period relaxes to 10.2s, and the direction is dominated by SW (27.5%), WSW (22.7%) and SSW (16.8%). Most of the energy now falls in the 1-2m range, turning the bay into a fun, rippable wave rather than a winter beast. Ideal wind falls to 26%, and the wind rose shows an important shift: NW winds jump to 16.3% and WNW adds 8.0%, both of which can add onshore bump. The improving water temp of 8.1°C (46°F) and lower average precipitation of 3.84 mm/day make late spring more pleasant, but you will still want to pick the early morning windows before the summer wind machine spins up.
