The hottest month to visit Disneyland in Anaheim, California, is typically August, followed closely by September. While June and July are also warm, August often sees "heat waves" where temperatures can climb well above 95°F (35°C). Unlike Florida, California has a "dry heat," but the sun in the Anaheim basin can feel very intense on the asphalt-heavy park grounds. In 2026, Disney has continued to mitigate this by installing more "misting stations" and shaded queues, but the humidity-free air means you may not realize how dehydrated you are getting. September can actually be trickier, as it is the peak of the "Santa Ana" winds, which can bring sudden, extreme heat even as the calendar moves toward fall. If you are sensitive to heat, the "Goldilocks" months of May or October offer much more pleasant temperatures while still providing the sunny California experience.
