Conditions at Hanalei Bay in June
June: Peak Trade Season, Minimal North Energy
June is the bottom of the curve for Hanalei. Average swell height is around 5ft (1.5-1.6m) and average period collapses to 8.2s. The swell table is almost entirely from ENE (54.0%) and E (24.6%), with NE at 12.4%; north and northwest swells are effectively absent. This easterly windswell has to wrap around the island, and the bay faces north-northwest, leaving only small, soft summer waves.
Winds are locked in the trades, with E and ENE totaling about 89%. Ideal surf windows (41%) are mostly limited to glassy early-morning hours before the trades fill in. Air temperature averages 25°C (77°F) and water sits at 25.6°C (78°F). If you want easy small waves or a fun longboarding session with the family, June works; if you are a winter swell chaser, this is the quiet month to wait out.
