July: Midwinter's Glassiest Offshore Windows

July offers the highest percentage of ideal surfing wind of the year at 30%, yet it remains a challenging month for Aramoana because the swell direction is mostly SSW/SW. Average wave height holds at 7ft (2.2m) and period stays strong at 11.2s. The ENE component rebounds slightly, and when an ENE swell pulse coincides with a south-west offshore wind, the NE-facing break can turn on with groomed, glassy walls. Winds are split between WSW, NNW, and NNE, so weather windows can be feisty and changeable. Air temps bottom out near 7.4°C, water temp drops to 9.9°C, and precipitation is drier at 1.46 mm/day. This is the month for the hardy local who knows exactly which banks hold the wrap swell under cold, autumn-like skies.
