Conditions at Baltrum in August
August: The Transition Begins - Whiffs of Autumn Swell
There's a subtle, almost imperceptible shift in August. The average swell height remains at 1.0m (3.3ft), but the period length starts to stretch out slightly to 5.7s, and the distribution of swells improves. The NNW and WNW swell directions are steady, but the most significant change is the increase in W and WSW swell, which brings more open-ocean reach. The wind starts to blow with a touch more autumn vigor, but the ideal wind frequency ticks up to a season-best 13%. This is also the warmest water month of the year, hitting 19.1°C (66.4°F) - the most comfortable surfing of the summer. The winds are still mostly light, keeping the surface mostly clean. While it is rare to find a wave above 1.5m, the late August build-up signals the start of the real swell season. Keep an eye on the long-range charts: if a low-pressure system forms off Greenland, Baltrum might just get a preview of the power to come. The period is short, but a solid 1.5m of clean NW swell will make the summer crowds very happy.
