Conditions at Langeoog in May
May: Summer Flatness Creeps In
May sees the surf energy continue to fade as the ocean tilts toward summer. Average swell remains 3ft (1.0m), but the average period drops to 5.8s, confirming that most waves are short-period windswell. The swell direction distribution is dominated by NNW at 26% and NW at 13.1%, but the height classes are weighted heavily toward the 0-3ft (0-1m) micro and small range. In other words, there can be waves, but they rarely have power. The wind rose shows a split personality: NNW/NW winds are frequent and onshore, while NE/ENE/E winds are also common, creating cross-shore and sometimes side-offshore texture. Only 11% of the time does the wind blow from the ideal offshore quarter. This is groveler season, when a longboard or a high-volume shortboard is the right call. If a low pressure system drifts across the North Sea and kicks up a WNW swell with SE winds, Langeoog can turn fun, but consistency is low. Air temps reach 10.9°C, water 11.6°C, and precipitation is modest at 1.54mm/day; a 4/3mm wetsuit with maybe a hood is still needed.
