Conditions at Inches in September
September: The Smallest Swell of the Year Meets a South-Swell Seed
September is the low point for wave height at Inches, with an average swell height of only 2.3ft (0.7m) and a period of 6.1s. Ideal wind is still a respectable 43 percent. The swell distribution is ESE-dominated at 48.1 percent, with E at 34.3 percent and SE at 11.3 percent. The SSE window appears more often at 2.7 percent, and a tiny S/SSW signal starts to show up, but it remains negligible in size. More than half of the energy is in the 1.5-3ft (0.5-1m) class, and the 3-5ft class is scarce. Winds become slightly more variable, with ENE and E each near 30 percent and the S/SSW/SW quadrant increasing to roughly 1 percent. Water temperature reaches its annual peak at 29.2°C, air averages 26.6°C, and precipitation rises to 4.4 mm/day. September is mostly a small-wave month, but the first tropical waves can produce clean, longer-period groundswell from the south if they align.
