Conditions at Cactus in July
July: Big Winter Swell With Bite
July delivers bigger and longer period surf: average wave height climbs to around 6.2ft (1.9m) and period to 13.6s. The swell energy is heavily weighted toward the SW (48.0 percent) with SSW at 20.3 percent and WSW at 8.7 percent, so Cactus is fully exposed to the full force of the Southern Ocean. There are plenty of 6.5-8ft (2-2.5m) and even 8ft+ (2.5m+) sets. However, ideal wind drops slightly to 22 percent, and W/SW/WSW wind events become more common - over 24 percent of observations. That makes July a month of extremes: either pumping, hollow lines under offshore early-morning winds, or stormy, blown-out churn. Water temperature drops to 15.6°C and air temperatures average just 12.7°C, so bring a hood and pick your days carefully.
