Conditions at Mullaghmore Head in August
August: Late-Summer Hints of a Change
August remains in the low season, but the numbers start to stir. Average swell inches back up to 3ft (0.9m) and period rises to 8.8s - still short-period, yet slightly more organized than July. WNW (36%) and W (21%) dominate, with NW (18%) and NNW (11%) continuing to fill the north-west window. The height distribution is more weighted to 0.5-1.5m, and a few 1.5-2m waves appear compared with July. Crucially, the wind regime improves: S/SSW/SW and WSW winds make up a larger share, and ideal wind conditions occur 32 percent of the time - tied with the best summer months. This is the last month you can expect warm water (16.4°C) and mild air (15.0°C), but also the first month when an early autumn low can send a proper 3-4ft (0.9-1.2m) groundswell out of the North Atlantic. If you're chasing a summer-to-autumn transition session, August is your best bet for clean, small-to-moderate Mullaghmore waves.
