May: Small, Clean and Quietly Fun
By May, average swell height drops to around 4ft (1.3m) and the period shortens to 9.1s, so Sandvik shifts from groundswell-focused to a mix of swell and windswell. The dominant directions remain SSW (16.2%), SW (19.0%), WSW (11.0%) and S (12.0%), but most of it is in the 0.5-1.5m range-fun-sized, groveling waves. The good news is the wind becomes more favourable, with ideal offshore conditions peaking at 18% of the time, the highest of the year. Air temperatures are milder at 6.1°C, water temperatures climb to 7.7°C, and precipitation falls to just 2.81mm/day. It is not the season for big barrels, but if you pick a clean morning with NE/E offshore flow, May can deliver playful chest-high peaks with fewer crowds and more light.
