Conditions at Skallelv in September
September: Autumn's First Breath
September is the first month that feels like the season is turning. Average swell height increases to 2ft (0.6m) and the period to 6.2s, pushing the surf from micro into small-but-rideable territory. The wave rose becomes more balanced - NNE (14.7%), NE (14.5%) and ENE (13.7%) lead, while the optimal E/ESE/SE/SSE block represents about 18% of the energy. It is not winter consistency, but the direction mix is much healthier than in summer. Wind is still a mixed bag: SSW (11.5%) and SW (11.4%) dominate, but the offshore W/NW/NNW group totals around 30%, and ideal conditions occur 13% of the time. Water temperature is a comfortable 9.1°C and air averages 7.0°C. Early autumn lows can produce surprise sessions with punchy windswell, especially when a W/NW wind grooms the SE-facing corner.
