July: Midwinter's Peak - Maximum Size and Offshore Flow
July sits at the climatological heart of the austral winter. The average swell remains at 9ft (2.8m), and the period lengthens to 12.5s, the highest of the year. Once again, offshore flow dominates: NNW (18.7%), NW (15.9%) and WNW (9.5%) are the primary wind directions, and ideal conditions clock in at 43%. Swell directions are remarkably reliable - SW (20.2%) and WSW (10.5%) lead the charge, with SSW (7.9%) and a growing W (2.6%) component from deep Southern Ocean lows. This is serious, heavy, long-period surf; 8-10ft (2.4-3.0m) sets are common, and XL days exceed 10ft (3.0m). Air temps bottom out around 14.1C, water at 14.9C, and rainfall averages 3.24mm/day. When a frontal passage aligns the NW wind with a fresh WSW swell, Betty's Bay can be world-class - though it will humble those not ready for the power.
