Conditions at Kastro Point in September
September: A Faint Pulse of Transition
September is the first month where the Mediterranean begins to stir again, but only barely. The average swell height is still a small 0.4m (1.3ft), the period is 4.5s, and ideal wind appears 15% of the time. The south quadrant improves slightly to 12.4%, led by SSW (5.3%) and S (3.7%), a suggestion of things to come. However, the dominant swell directions remain WNW (25.2%) and NW (18.5%), which are not Kastro's friends. Water temperature is still warm at 24.2°C, air averages 21.1°C, and rainfall increases to 2.42 mm/day as the first autumn fronts brush the region. Late September can produce a surprise SSE/S swell from a pre-season cyclone; if that coincides with a N/NNE offshore wind, you might grab one proper session before the real season begins.
