Conditions at Carrownisky in August
August: Summer Lull with a Hint of Change
August remains deep in the low season, but the Atlantic starts to show faint signs of life toward the end of the month. Average swell height is 3ft (1.0m) and the period is still short at 8.3s, leaving most waves in the small, wind-driven category. The dominant swell directions - W (28.1%), WNW (21.9%) and WSW (16.2%) - are technically ideal for the beach, but the lack of period and size means the surf lacks any serious push. August actually has the lowest ideal wind percentage of the year at 11%, with SW/WSW/W/WNW winds making up nearly 45% of the wind rose. That is an onshore recipe, and Carrownisky can stay messy for days on end. Yet the water is at its warmest, 16.5°C (62°F), and the rare combo of a developing North Atlantic low and a NE/E offshore wind can produce fun, waist-high, clean peaks as the month winds down. Keep the longboard waxed, but don't plan a swell-chasing trip around August.
