Conditions at Sandy Hook in June
June: Summer Mode Engaged
June is the official start of summer surf, and the numbers reflect it. Average swell drops to 0.9m (3ft) at a modest 6.9 seconds, while the best swell directions shrink to under 13% of the wave rose. The wave climate is dominated by SSE and S windswell, which struggles to find quality shape along the east-facing shoreline. The silver lining is wind: ideal offshore conditions jump to 56%, with southwest and west winds in the 10-20kph range prevailing. This allows clean, knee-to-waist-high waves on almost any morning, especially when the seabreeze is still asleep. Water temperature is a pleasant 17.5°C and air averages 19.7°C, so the summer surf kit starts to spread out. It's small, but longboard-friendly and super pleasant.
