Conditions at Muizenberg in July
July: Peak Season at the Cape of Storms
July is the statistical peak of the Muizenberg surf calendar. Average swell height peaks at around 9.5ft (2.9m), and average period stretches to 12.6s - the longest of the year. The waverose remains concentrated in the SW (18.4%), WSW (9.8%), SSW (8.5%), S (2.9%) and W (2.6%) quadrants, with plenty of 2-2.5m (6.5-8ft) energy and a serious chunk of XL sets above 2.5m. This is the time when long-period Southern Ocean groundswell wraps into False Bay and unloads on the sandbanks. On the wind side, NNW (23.5%), NW (8.0%), N (5.1%) and NNE (3.3%) hold the offshore flow steady enough for a 30% ideal rating. SE (13.5%) and SSE (12.2%) still blow, but they are no longer the rule. Air temperatures bottom out near 11.8°C, water temp is 14.7°C, and precipitation is high at 3.70 mm/day. If you want a true winter session in Cape Town, this is the month to be at Muizenberg.
