Generally, yes, wait times for outdoor attractions at Disney Parks tend to decrease significantly during the rain. Many casual guests and families with young children head for the exits or seek shelter in gift shops and restaurants when a downpour begins, leading to a "drainage" of the park's general population. However, there is a catch: if the rain is accompanied by lightning or high winds, outdoor rides (like Big Thunder Mountain or Slinky Dog Dash) will be temporarily closed for safety, which actually drives people into the indoor attractions (like Pirates of the Caribbean or Haunted Mansion), causing those specific lines to spike. In 2026, the best "rainy day" strategy is to pack a high-quality poncho and head to the indoor rides as soon as the clouds darken. If the rain is a steady, light drizzle without lightning, most rides stay open, and you can often find "walk-on" wait times for even the most popular attractions while other guests wait for the sun to return.
