September: Autumn Warmth and the First Pulse of Power
September is a transition month that knows how to surprise. The average swell rises to 5-6ft (1.5-1.6m) and the period lengthens to 10.5s, pushing back into the long-period range as the Atlantic starts to stir. Directionally, NW is king at 34.1%, with WNW at 22.8% and NNW at 22.4%, a solid spread across the optimal window. The tables show more wave heights in the 5-8ft (1.5-2.5m) range than the summer months, and the first true 8ft-plus (2.5m+) pulses can appear from early autumn storms.
Wind quality improves noticeably to 41% ideal, as the continental high shifts and early low-pressure systems bring ENE/E/ESE/SE offshore winds. NNW is still the single most common wind direction at 22.9%, but the frequency of easterly offshore flow grows as the month progresses. With air at 18.8C, water 16.5C and rain picking up to 2.2mm/day, September is arguably the best month of the fair season, warmer than winter and significant enough to make your eyes light up.
