Conditions at Juist in August
August: Warmest Water, Ugly Windswell
August is the peak of the warm-water season and the bottom of the surf-quality curve. The average swell height remains at 2.6ft (0.8m), the period sits at 5.3s, and most of the wave rose is filled with low-energy windswell from the NNW, NW and W sectors. NNW is still the single largest swell direction at 21.7%, but the 3-5ft (1-1.5m) and bigger classes only make up small fractions. In other words, the North Sea is mostly a swimming pool. Wind conditions are dominated by WSW, W and WNW, with SW also well represented. These directions rarely give Juist a clean offshore flow; ideal wind appears only 6% of the time. Air temperatures peak around 18.0°C and the water reaches its warmest of the year at 19.4°C, which makes the summer sessions comfortable even when the waves are poor. Precipitation averages 2.62 mm/day, often in the form of showers along weak fronts. You can score a fun summer wave if a low-pressure system tracks far enough south to send a northwest swell, but expect bumpy, short-period conditions.
