Conditions at Sylt in May

May: Spring's Small Windows

May is the beginning of the annual surf lull. Average swell height bottoms out at 3ft (0.9m) and average period drops to 5.5 seconds, pushing the surf into choppy, low, messy territory. The swell direction rose is still loaded with NW (21.0%) and NNW (16.7%) energy, but almost all of it is short-period windswell sitting in the 1.5-3.5ft (0.5-1m) class; only a small share reaches 3-5ft (1-1.5m). Wind conditions are mixed: ideal offshore ENE-E-ESE-SE winds blow 24.7% of the time, but the onshore northwesterly quadrant remains active, with NW at 11.5%, NNW at 13.2% and WNW at 8.6%. The combined bad-wind quadrant totals 34%, so blown-out days are common. The saving grace is improving weather: water temperature warms to 11.3°C, air temperatures average 10.9°C and precipitation is only 1.55 mm/day. Bring a grovel board and chase the early summer windows.
