What September feels like
Locals call the first stretch second summer: the storms thin out and the heat has no intention of leaving. By the last week the evenings turn usable again and the patios start filling after sunset.
Real rain shows up about 2 days all month; the rest stay dry. Humidity stays comfortable; the air never feels heavy. Most afternoons push past 90°.
