Conditions at Kilcummin in August
August: Late-Summer Consistency
August is a modest step up from July. Average swell climbs back to 1.0m (3ft) and the period to 9.0s, still short-period but with a slightly better spread of 1.5-2m waves in the W-WNW quadrants. The wave rose remains heavily weighted toward W (28.9 per cent) and WNW (34.7 per cent), while NW is 13.3 per cent, giving a preferred N-NNW-NW share of about 17 per cent. The big improvement is wind: the ideal-wind figure jumps to 36 per cent, with S-SSW-SW around 28 per cent and northerly onshore directions down to about 20 per cent. That means more glassy, clean sessions on mostly small swell. Air temp is 15.1°C, water temp is the warmest of the year at 17.4°C, and precipitation is moderate at 3.62mm/day. It's still summer out there, but the ocean is starting to hint at the change to come.
