Yes, September is statistically one of the wettest months for Walt Disney World in Orlando. This coincides with the peak of the Florida hurricane season, resulting in an average of 13 to 17 rainy days throughout the month. Most of this precipitation occurs as short, intense afternoon thunderstorms that can dump several inches of water in a single hour before the sun returns. While these bursts rarely ruin an entire day, they are predictable enough that you should pack a high-quality poncho or umbrella. The silver lining is that rain often clears the outdoor crowds, leading to significantly shorter wait times for indoor attractions. In 2026, Disney continues to monitor weather patterns closely, and while "all-day" washouts are rare unless a tropical system is nearby, visitors should prepare for high humidity (often exceeding 80%) alongside the frequent, refreshing afternoon deluges.
