Conditions at Sandy Hook in July
July: Glassy, Small and Mellow
July is the low point of the swell calendar at Sandy Hook. The average wave height bottoms out at 0.8m (2-3ft) with a 7.0-second period, and the optimal swell directions account for barely 6% of the rose. SSE and S swells take over, contributing over 60% of the wave energy, but they struggle to deliver anything remotely powerful to this beach. On the plus side, ideal wind conditions peak at 62%, with a persistent southwest flow blowing offshore and keeping the surface silky. Dawn patrol is the move: warm 20.3°C water, mild 23.5°C air, and the occasional knee-high set rolling through a beautiful summer sandbar. It is not a wave of the year candidate, but it is a fantastic month for beginners, longboarders and anyone who values a smooth ocean over a heavy wall.
