Conditions at Hanalei Bay in July
July: Small, Glassy Mornings and Trade-Wind Afternoons
July remains in the summer doldrums. The average swell height is 5ft (1.5m), the period is 7.8s, and the direction mix is dominated by ENE (65.6%) and E (25.9%), with NE at 6.1% and almost no north-northwest energy. Hanalei receives small, crumbly, mostly shadowed trade swell that is best handled on a longboard or a groveler.
The wind blows from E and ENE about 92% of the time, although ideal conditions are seen 37% of the time, almost always as dawn glass before the daily trades kick in. Water temperature reaches a balmy 26°C (79°F), air is warm, and rain is minimal. July is, in short, a longboard playground rather than a serious wave destination.
