Conditions at Carrownisky in April
April: Cleaner but Smaller
April is the first month of the year where clean conditions become more common than heavy storm surf. Average swell height is down to 4ft (1.3m) and the average period drops to 10.6s, so the surf is less powerful and more punchy than in the winter months. The swell rose is interesting: WNW (20.9%) edges out W (18.7%), and there is a strong NNW/NW component (13.6% and 11.5%) from lows passing to the north. That west-northwest energy still lines up well at Carrownisky. Most waves now fall in the 2-5ft (0.5-1.5m) range, with fewer big sets. The big story is wind: ideal offshore conditions occur 21% of the time, the highest of the year. NNE (8.1%) and NE (5.7%) flows, along with E/ESE breezes, can groom the W/WNW swell into clean, rippable peaks. Air temperatures average 8.8°C (range 1.3 to 16.9°C), precipitation is the year's lowest at 2.88 mm/day, and water temperature climbs to 10.0°C (50°F). It's not pumping, but it's fun and far less chaotic.
