Conditions at Byberg in May
May: Summer Windswell and the Great Letdown
May is the first full month of the low season. Average swell height slides to 2-3ft (0.8m), the period drops to 6.8s, and ideal surf wind falls to just 8%. The swell-direction tables still show a lot of NW (28.4%) and WNW (16.2%), but these are increasingly local wind waves generated by the same westerly to northwesterly flow that puts onshore bumps on the surface.
Offshore winds from E/ESE/SE/SSE only total 23.8%, while the NNW wind direction alone is 26.9% and NW another 13.2%. That combination smashes any potential for quality. Air temperatures become more comfortable at 9.2°C and water warms to 9.0°C, so sessions are less about survival and more about chasing rare windows. Bring a high-volume board and look for early-morning east winds; otherwise, accept the walls of small, lumpy storm chop.
