Conditions at Norderney in September
September: The Autumn Resurgence
September is the reliable reawakening of the North Sea. The average swell jumps to 1.3m (4.3ft) and the period lengthens to 6.3s, while the directional spread becomes more balanced: NNW (16.4%) and NW (11.7%) still lead, but solid W and WNW contributions (10.7% and 10.8%) reflect strengthening Atlantic lows. This is also the best month of the year for clean conditions - ideal wind reaches its annual maximum of 16%. The wind rose shows a healthy balance between westerlies and the offshore SSW-SE quadrant, so the number of rideable, groomed days increases markedly. The sea is still warm at 17.3°C and the air averages 15.0°C, making September arguably the most pleasant month for surfing Norderney: real swell, offshore windows, and no need for a hood.
