Conditions at Juist in May
May: The Summer Lull Takes Hold
May marks the beginning of the low season for surf at Juist. Average swell height is 2.6ft (0.8m), period drops to 5.2s, and the North Atlantic is largely quiet under a building ridge of high pressure. NNW still dominates the swell direction chart at 29.3%, but an enormous amount of that energy is 2-3ft (0.5-1m) or smaller. There are only small traces of 3-5ft (1-1.5m) wave heights from the W, WNW and NW sectors. Wind conditions are not on our side either. NE and ENE are frequent, along with NNW, which adds up to plenty of side-shore and onshore chop. The ideal offshore sector manages only 6% of the time. Water temperature warms to 12.3°C, air average is 11.9°C and precipitation is moderate at 1.79 mm/day. May can still deliver a surprise northwesterly groundswell, but the percentages say that most days will be windswell and small waves best suited to a soft top or a longboard.
