Conditions at Kilcummin in July
July: High Pressure and Small Waves
July is the heart of the Irish summer and the Atlantic is at its most sluggish. Average swell is 0.9m (3ft) and the mean period is just 8.8s - the least powerful of the year. The wave rose is dominated by W (29.6 per cent) and WNW (32.5 per cent), but these are not the ideal angles for Kilcummin. The preferred N-NNW-NW share drops to about 19 per cent, and the few waves that do wrap in are generally waist-to-chest high. Wind conditions are not terrible - the ideal-wind figure is 33 per cent, with S-SSW-SW about 26.5 per cent - so onshore chop is not constant, but the lack of wave energy means you have to pick the best swell window. Air temp averages 15.0°C, water temp peaks at 17.0°C, and precipitation is 3.54mm/day. A 3/2 wetsuit is enough, and a summer shortboard or fish will get the most out of these small, clean days.
