Conditions at Hellesto in May
May: Long Days, Small Waves
May marks the real start of the low season for surf at Hellesto. Average swell height falls to about 2-3ft (0.8m) and the average period drops to 6.8s - noticeably more windswell, less groundswell. Although NW is the dominant swell direction at 28 percent and WNW adds another 16 percent, the energy is overwhelmingly in the under-1m categories, leaving the beach with knee-to-waist high lumps rather than clean waves. Ideal wind conditions are scarce at just 7 percent, and with spring warmth the thermal wind machine starts to spin up, making the NNW flow a frequent companion. Air temps have climbed to 9.2°C, water to 9.0°C, and precipitation is at the yearly minimum of 2.61 mm/day - great weather for beach walks, but not for serious surfing. Longboarders and beginners will get the most out of May.
