August: Hurricane Season Whispers
August remains small, with average wave heights around 0.9m (3ft), but the period rises to 7.5 seconds, hinting at the first long-period tropical energy of the season. The E direction starts reasserting itself at 9.4% of the swell rose, while SE and SSE still dominate the distribution. With ideal wind at 58% and southwest/west winds blowing offshore on many afternoons, Sandy Hook remains clean even when the waves are modest. Water temperature reaches its annual peak of 22.0°C, air averages a summer-like 23.4°C, and precipitation is relatively high. The wildcard is the tropics: when a hurricane or tropical storm lifts up the Southeast coast, Sandy Hook can suddenly see clean E swell wrapping into the sandbars, delivering the first real taste of the fall season while the water is still warm.
