Conditions at Cape Town in July
July: Mid-Winter Maximum
July is the statistical peak of the Cape Town surf year. Average swell height reaches 9-10ft (2.7-3.0m) and period hits 12.6s, the highest of the entire year. SW groundswell dominates at 18.4%, with WSW 9.8%, SSW 8.5% and W 2.6%; the over-2.5m (8ft+) category is at its yearly maximum, so XL days are definitely on the table. Wind remains the great equalizer: the NW/NNW quadrant controls more than 31% of the rose, but SE (13.5%) and SSE (12.2%) still offer clean offshore windows. The ideal-wind ratio is 36%, meaning you have to pick your moments. Water temperature drops to 14.2°C, air temps average 14.3°C and rain is high at 2.43mm/day. For confident surfers, July's combination of long-period S/SW groundswell and offshore ESE/SE winds is about as good as it gets.
