Conditions at Dunmoran Strand in May
May: Small, Clean and Fun
May sees a serious step down in size as the Atlantic transitions toward summer. Average wave height drops to 1.4m (4-5ft) and average period to 9.6s, so the surface often carries windswell rather than true groundswell. The directional spread is nicely spread through the west-to-northwest quadrant: WNW 19.6%, W 15.3%, NW 17.4%, and a strong NNW 19.9%. The NNW and NW percentages are a big positive for the north-northeast-facing beach, giving it plenty of workable, if modest, swell angles. Ideal offshore winds from the south and southwest blow around 26% of the time, but the dominant NNW wind (13.4%) will occasionally chop things up. Water temp climbs to 11.3°C and air temps reach 11°C, making this the month when wetsuit thickness starts to drop. On a clean day you'll be surfing small, rippable peaks - perfect for longboards and high-performance shortboards alike.
