Conditions at Carrownisky in July
July: Flat Spells and Onshore Winds
July is the slowest month of the year at Carrownisky. Average swell height bottoms out at 3ft (0.9m), and the average period is a meager 8.0s - bottom-of-the-scale windswell energy. The swell rose is full of W (26.9%), WNW (21.5%) and WSW (16.7%), but these are mostly small, short-period waves generated by local winds rather than distant North Atlantic storms. There is almost no swell above 6ft (2m), and most days will be lucky to see 1-2ft (0.3-0.6m) on the sets. The wind picture is poor too: ideal offshore winds only occur 12% of the time, while SW/WSW/W/WNW combine for over 40% of the observations, making the beach frequently lumpy and onshore. A rare early-morning NE/E offshore breeze can tidy up the small W/NW swell for a session on a longboard or SUP, but expectations should be low. Air temperatures peak around 14.7°C (range 9.1 to 24.6°C), rainfall is 3.53 mm/day, and water temperature reaches 15.8°C (60°F) - the warmest of the year, if that helps.
