Conditions at Portrush in August
August: Late Summer Lull with an Occasional Bite
August stays locked in the summer pattern, but there is a hint of life returning. Average swell nudges up to 3-4ft (0.9-1.2m), period sits at 8.3s, and the swell rose remains packed with W at 28.2% and WNW at 31.3% energy. The problem is that most of it is small and short-period. Ideal offshore wind windows are still around 18%, but the NNW/NW sea breeze and occasional W winds mean you have to be picky about tides and timing. When a late-season tropical system or early autumn low drifts into the Atlantic, Portrush can throw a solid 4-6ft (1.2-1.8m) summer surprise.
The warmest water of the year at 15.6°C meets air temps of 14.1°C and 3.50 mm/day of rain. Good time to squeeze into a springsuit and enjoy the rare clean lines.
