September: Tropical Energy and Transitional Winds
September is the month when Rockaway starts to turn back on. The average swell rises to 1.1m (3.6ft) and the average period stretches to 8.3s - the longest of the year - signaling a mix of tropical pulses, early extratropical systems and post-tropical cyclones. ESE (20.2%), SE (18.7%), E (15.5%) and SSE (14.5%) dominate, with S (9.3%) still in the mix. The wind picture is more balanced than mid-summer: SSW (9.4%) and S (9.0%) remain frequent, but NNE (5.3%), NE (6.0%), ENE (7.3%), NW (6.5%) and NNW (9.5%) provide valuable clean windows. Ideal wind scores a year-high 31%. Water is still warm at 21.5°C (71°F), so early-fall hurricane swells can be incredibly fun before the winter lineup fully organizes.
