Conditions at Cox Bay in August
August: Small Swells, Warm Water, Westerly Grip
August is a mirror of July: average swell height sits at 4ft (1.2m) with a period of 11.3s. W swell takes the lead with 41.8%, while WSW contributes 29.9%, SW 14.1% and WNW 9.8%. Most waves are in the 1-1.5m range, so it is still small-scale surfing. Wind patterns remain unfavourable for a west-facing beach: WNW is again the most common direction at 33.2%, W adds 16.0% and NW 9.8%, while offshore E/ESE flow is isolated to brief cleaner windows. Ideal wind improves only slightly to 19%. Water temperature reaches its warmest at 14.2°C (58°F), air temps average 14.9°C (59°F), and precipitation stays low at 2mm/day. If you want summer surfing, look for early morning offshore breezes and small WSW groundswells; otherwise, August is for the pool.
