Conditions at L'Ideale in September
September: First Glimmers of Autumn
September is a quiet turning point. Average swell height remains small at around 2ft (0.6m), but the period ticks up slightly to 4.3s, and the first mid-latitude lows begin to brush the western Mediterranean. The direction rose still favours WSW (15.0%), S (14.4%) and SW (11.9%), but the WSW sector shows more meaningful 3-5ft (1-1.5m) and even 5-6.5ft (1.5-2m) energy than summer. A strong September storm can occasionally line up a proper west swell and surprise everybody.
Ideal wind improves to 9%, but sea breezes and SE/SSE flow still rule many days. Air temps remain warm at 21.9°C, water temp is still toasty at 23.1°C, and rainfall starts increasing to 2.67mm/day. Start watching the charts more seriously in the final week of September; the autumn storm track is warming up.
