Conditions at Klitmöller in September
September: The Atlantic Wakes Up
September is a genuine transition month. The North Atlantic low-pressure track begins to fire again, pushing average heights up to around 5ft (1.5m) and period to 6.6s. WNW (14.0%) and NW (11.8%) regain their grip on the wave rose, with a growing share in the 5-8ft (1.5-2.5m) range. Offshore wind frequency ties for the annual high at 22%, and the wind rose becomes more balanced between westerly and southerly flow. Water is still warm at 16.0°C, air averages 14.2°C, and precipitation begins to increase. September is one of the best windows of the year: enough power, enough warmth, and still enough clean days.
