Conditions at Porth Neigwl in August
August: Summer Fizz and Tropical Possibilities
August is very similar to July, with an average swell of 4ft (1.2m) and a period of 8.4s. The W (36.5%) and WSW (20.4%) directions dominate the wave rose once again, but most of that swell is short-period and small. The upside of August is the ocean has reached its warmest water temperature of 17.4°C, while air averages 16.7°C, making it the most pleasant time to be in the water. Ideal offshore E/SE wind is rare at 16%, so clean days are limited and often tied to overnight offshore breezes or the brief passage of a weak front. Occasionally, a decaying Atlantic hurricane or tropical storm can send long-period SW/W swell into the region, giving Porth Neigwl a rare summer taste of proper waves. Otherwise, keep expectations low and the wax soft.
