Conditions at Scripps in September
September: Late Summer South Swell Still Rules, but Change Is Coming
September is the pivot month. Average height rebounds slightly to 1.0m (3.3ft), period stays long at 13.6s, and the swell mix is still summer-like: SW 41.8%, WSW 34.0%, and SSW 16.0%. There is a subtle increase in W/WSW energy, hinting at the autumn transition. Winds, though, are still against you. Ideal wind is just 5%, with WNW (34.6%) and NW (20.2%) dominating the shoreline. An early season cold front can reset the pattern and deliver offshore ENE flow, but those days are rare. Air temps are warm at 21.3°C, rainfall remains minimal at 0.18mm/day, and water temp is at its warmest with 19.7°C. Keep expectations in check until October.
