Conditions at Sylt in June
June: The Summer Lull
June marks the heart of the summer lull on Sylt. Average swell height holds at a weak 3.3ft (1m), and the average period remains a marginal 5.6 seconds, right on the edge of choppy and messy. The dominant swell direction is NW (26.2%), with WNW (13.2%), WSW (11.2%) and W (10.4%) also contributing, but the wave heights are overwhelmingly in the 1.5-3.5ft (0.5-1m) range, with only occasional 3-5ft (1-1.5m) sets. The bigger issue is wind: the onshore WSW-W-WNW-NW quadrant makes up 45.6% of the wind rose, while ideal offshore ENE-E-SE winds are scarce at just 14.8%. This combination creates bumpy, windblown conditions more often than not. Water temp climbs to 15.1°C, air temps average 14.2°C, and precipitation is 2.16 mm/day. It feels pleasant, but the surf is mostly weak and disorganized. A rogue summer low can still fire up a punchy NW swell, but wind and short periods usually keep it messy.
