The weather in Orlando is at its hottest from mid-June to mid-September. Temperatures average as high as 82°F (28°C) in August, with nighttime lows rarely dropping below 72°F (22°C).

Weather in Orlando during July and August 2026 is characterized by intense heat, high humidity, and near-daily afternoon thunderstorms. Daytime highs consistently hover around 91°F to 93°F (33°C–34°C), but the humidity often pushes the "RealFeel" or heat index into the 100s. Thunderstorms typically roll in between 2:00 PM and 5:00 PM, bringing heavy rain and lightning that can temporarily close outdoor rides; however, these storms are usually short-lived and help clear the air. Humidity remains high even at night, with lows rarely dropping below 75°F (24°C). For travelers, this is the most demanding time of year physically, requiring moisture-wicking clothing, frequent "A/C breaks" in shops or shows, and a flexible itinerary that accounts for potential weather-related delays during the late afternoon.
