August is the steamiest month, with average highs of 91 degrees and average lows of 76.8 degrees. Add the humidity to that, which is highest in August and September at 77 degrees, and you have some heat! August is also the rainiest month, with 24.6 days on average of precipitation.

In 2026, August remains the most humid month in Orlando, Florida. While the entire summer period from June to September is characterized by high moisture levels, August typically sees the peak of the subtropical "mugginess" with an average relative humidity of around 78% to 80%. During this time, the dew points frequently stay in the mid-70s, making the "real feel" temperature significantly higher than the actual thermometer reading. For travelers visiting Disney or Universal, this translates to heavy afternoon thunderstorms almost daily and a "sticky" atmosphere that persists even after the sun goes down. In 2026, park-goers are heavily advised to plan their outdoor activities for the early morning or late evening and to utilize the many climate-controlled "chill zones" now integrated into most major attraction queues to combat the intense humidity-driven heat index.
