Conditions at Waitpinga in July
July: Deep Midwinter Power
July is the heart of the Southern Ocean season. Average swell height is 4-5ft (1.2-1.5m), period is 12.0s, and the direction mix continues to shift west. SW now leads at 33.9%, just ahead of SSW at 32.4%, with WSW at 10.6% and W at 5.4%. This westerly component generates long, powerful groundswell that pushes right into the SSW-facing coastline. The 5-6.5ft (1.5-2m) range is solid, the 6.5-8ft (2-2.5m) range remains present, and the biggest swells start to show over 8ft (2.5m).
Wind is more dynamic than May or June. NNW is the dominant offshore direction at 16.3%, but the NW/WNW sector is also strong, reflecting the parade of lows crossing the Bight. That means Waitpinga can swing from clean, offshore perfection to stormy WSW/SW slop in a matter of hours. Ideal wind is 29%. With air at 11.2°C, water at 14.3°C and rainfall at 2.18mm/day, these are winter surf sessions through and through. If you pick the right day, the reward is some of the heaviest, most grinding surf of the year.
