Conditions at Campelo in May
May: Smaller Waves, Springtime Windows
May signals a definite easing in the North Atlantic. Average swell heights fall to around 5-6ft (1.5-1.8m), the period settles at 10.0s, and the ideal wind percentage slips to 26%. Directionally it is a very lively month: WNW (22.1%), NW (21.6%) and NNW (18.5%) still dominate, but the height distribution clusters in the 0.5-1.5m range, so waves become more playful and less intimidating. The wind pattern has shifted to a summer-like NE/ENE regime, with NE (15%) and ENE (11.6%) frequent, meaning quality usually comes early before the sea breeze can chop things up. Air temperatures climb to 13.8°C, precipitation is just 2.29 mm/day, and water temperature reaches 14.7°C. It is a good month for longboarding and groveling on the better NW swell days.
