May: Clean Summer-Style Mornings on Smaller Waves
May is the first month where the surf calendar truly flips from raw power to rideable fun. Average wave height drops to around 5-6ft (1.7m), and the period eases to 10.2s, while SW and WSW swells remain dominant at a combined 50%. The good news is the wind: offshore flow from W/WNW/NW/NNW reaches about 36%, with northwest winds becoming a regular coastal feature. This creates clean, glassy mornings and plenty of lined-up waves, even if the size is moderate. True E/SE swell still accounts for just 2-3%, so the big summer northeast swell machine has not yet kicked in. Water temperature is 8.1°C, air temps average a milder 7.9°C, and precipitation falls to 3.84 mm/day. This is a great month for going smaller in board size and enjoying cleaner conditions.
