Conditions at Agger in May
May: Clean Smaller Days
May is the beginning of the long summer lull, but the North Sea rarely goes flat. Average swell height drops to 3-4ft (0.9-1.2m) and period to 6.1s, with WNW and NW swells still accounting for a remarkable 35.9% of observations. The problem is wave quality: many of those waves are in the 0.5-1m range, and short-period NW windswell can be sectiony and soft. Offshore wind frequency slips to 15%, while west through northwest onshore winds now blow just over 40% of the time, meaning the window for really clean surf is shrinking. Air and water temps reach 10.1°C, and precipitation is low at 1.8mm/day. Keep your expectations modest - this is spring suit and small-wave board territory, not heavy North Sea charging.
