As of 2026, Orlando in September averages a high of 32°C and low of 23°C with 160mm of rain over about 13 days. Still hot and humid — highs around 32°C, lows near 23°C. Lightweight breathable clothing and a rain poncho for afternoon storms. Very high UV (index 10): SPF 50+, hat, sunglasses, and hydration essential.
September is moderate for Orlando.
September is a hidden gem for crowds and value — with US kids back in school, it has some of the lowest crowds and best hotel rates of the year. The weather is still hot and humid (highs around 32°C) with afternoon storms, but the thin crowds make a real difference.
This is when seasonal Halloween events ramp up at both Disney and Universal (Universal's Halloween Horror Nights is a major draw), adding nighttime entertainment. Short ride waits and lower prices are the big wins this month.

Orlando in September — Full Picture
September is a hidden gem for crowds and value — with US kids back in school, it has some of the lowest crowds and best hotel rates of the year. The weather is still hot and humid (highs around 32°C) with afternoon storms, but the thin crowds make a real difference.
This is when seasonal Halloween events ramp up at both Disney and Universal (Universal's Halloween Horror Nights is a major draw), adding nighttime entertainment. Short ride waits and lower prices are the big wins this month.
The catch is hurricane season: September and October are the peak risk window, so tropical systems can bring heavy rain, wind, and possible closures. Consider travel insurance, watch forecasts, and keep your plans flexible.
Note: if you can tolerate the lingering heat and accept the hurricane risk, September offers the best combination of small crowds and low prices in the whole year.
What to Wear & What to Pack
