Conditions at Varazze in September
September: The First Stirrings of Autumn
September marks the beginning of a slow upward trend. Average swell rises slightly to 1.5ft (0.5m) and the period to 4.4s, while SSW remains the dominant swell direction with 24.8%, followed by SW at 17.9% and a notable increase in N swell to 7.9%. The wind distribution becomes more favorable again as NNW flow returns to 32.0%, helping push the ideal surfing percentage up to 15%. The first low-pressure centres of autumn begin moving through the Gulf of Genoa, bringing more precipitation (2.78 mm/day) and the chance of freshly generated SSW swell. Still, most September waves are small and short-period, so do not expect much over 2-3ft (0.6-0.9m). Water temperature remains warm at 22.0°C and average air temperature is 18.7°C, so lighter wetsuits make the occasional grovel session pleasant. The longer the month progresses, the more often a cold front can produce the classic offshore NNW wind that turns the SSW swell into clean, rideable peaks.
