Yes, Disney parks frequently cancel or delay fireworks due to storms and adverse weather conditions. In 2026, safety remains the top priority; shows are typically called off if there is lightning within a specific radius (usually 6–10 miles) or if high-altitude winds exceed safe thresholds for pyrotechnic fallout. While light rain generally doesn't stop a show, "wind shears" can blow debris into guest areas, making cancellation necessary. In 2026, Disney utilizes sophisticated real-time radar and automated notification systems via the My Disney Experience and Disneyland apps to alert guests. If a show is cancelled, Disney rarely offers a refund specifically for the fireworks as they are considered "complimentary" entertainment, though they may occasionally schedule a "replacement" show if conditions clear up later in the night.
