Disney World has a very nuanced policy regarding fireworks and wind, where safety for both guests and "backstage" areas is the primary concern. Fireworks shows like Happily Ever After or Luminous can typically proceed in light to moderate rain, but high winds are a different story. If sustained winds or gusts at the pyrotechnic launch heights exceed specific safety thresholds (usually around 10–15 mph depending on the direction), the show may be delayed or certain high-altitude shells may be cut from the performance. If the wind is blowing directly toward guest areas or sensitive wooden structures (like those in Frontierland), the show may be cancelled entirely to prevent falling embers or "fallout" from reaching people. In 2026, Disney utilizes sophisticated real-time weather monitoring to make these calls at the last possible second. While a complete cancellation is rare, "modified" versions of the shows are common during the windy spring months. If a show is cancelled, Disney does not typically offer refunds on park admission, but they will often try to reschedule the performance for later in the evening if the weather patterns show a favorable window for "safe" pyrotechnics.
