Conditions at Inside Lefts in September

September: Big and Mostly Unruly

September keeps the swell furnace burning, averaging around 6.5ft (2.0m) with a 14.1s period. The direction is even more S-dominated: S delivers 55.7 percent of all readings, including 26.0 percent in the 5-6.5ft (1.5-2m) range and 24.9 percent in the 6.5-8ft (2-2.5m) range. SSW still contributes 24.0 percent, with a notable 11.5 percent in the 5-6.5ft (1.5-2m) class.

But the wind climate is at its worst. SE dominates with 56.1 percent and SSE adds 29.7 percent, leaving just 10 percent ideal wind windows. Much of this flow is 20-40kph, so the surface is frequently chopped and the peak is hard to read. Rain is still low at 2.65mm/day, air temperature is 26.9C and water is 28.4C. Expect occasional magic windows between trade pulses, but this is a low-percentage month for clean Inside Lefts.
