September in Orlando remains hot and humid with highs of 90°F, though the frequency of afternoon storms begins a slow decline to 14 days. Breathable, quick-dry fabrics are still essential for the 8–12 miles of walking at Walt Disney World, especially during the humid midday hours. A poncho is still a core requirement for Universal Orlando, as the tropical weather pattern continues through the end of the month.
September is an extension of the Florida summer, with 90°F temperatures and high humidity that keeps the heat index in the triple digits. While the 14 days of rain are slightly fewer than in August, the storms remain torrential and can arrive suddenly while you are walking the long distances between parks or exploring the International Drive corridor. This is also peak hurricane season, which can occasionally bring more sustained wind and rain to the 25,000-acre Walt Disney World Resort. The local style remains casual and athletic, with a shift toward darker colors for the transition into fall, though the fabrics remain strictly lightweight. Visitors often underestimate how hot September stays; it is not yet time for sweaters or boots. Most locals continue to wear performance sneakers and moisture-wicking shorts to manage the 90°F heat while navigating the concrete-heavy terrain of the theme parks and Universal's Islands of Adventure.

Packing List
What to Pack for Orlando in September →
Stick to your mid-summer wardrobe: moisture-wicking shorts, breathable t-shirts, and lightweight synthetics. The humidity remains high enough that 90°F feels much hotter, so prioritize comfort and airflow above all else.
September is one of the quietest months at Walt Disney World and Universal, making it a favorite for those who want lower crowds and don't mind the 14 days of rain and lingering 90°F heat. Just be aware of the potential for tropical weather disruptions.
Cushioned, breathable running shoes are still the gold standard for the 8–12 miles of walking. Because it is still very rainy, ensure your shoes have good traction to handle slippery concrete at Universal Studios after a storm.
It remains very warm, with average highs of 90°F and lows of 73°F. The humidity doesn't typically start to break until the very end of the month, so expect 'summer' conditions throughout your trip.
Pack a reliable poncho, plenty of breathable summer clothing, and high-quality walking shoes. Sunscreen and hydration remain top priorities as the Florida sun is still intense enough to cause fatigue during long park days.
