Conditions at Orre in September
September: The First Autumn Pulse
September marks the first real shift back towards surfable conditions. Average swell height rises to 3-4ft (0.9-1.2m), and the wave period improves to 7.1s. The North Atlantic is waking up from its summer slumber, and the first strong lows of autumn start to send fresh W and WNW swell towards Norway. With W and WNW both at 13.8% of all swell readings, and NW still contributing heavily, Orre begins to see more organised lines.
Ideal offshore wind improves to 9% of the time, and E/ESE windows become more common as high pressure builds over Scandinavia. NNW winds are still frequent at 19.6%, but they are less dominant than in summer. Water temperature is still pleasant at 15.1°C, air averages 12.8°C, and precipitation increases to 4.99 mm/day. September is the month to keep an eye on the forecast; the first proper groundswell of the season can catch you by surprise.
