Can fireworks be set off on rainy or windy days?

Multiple safety hazards of setting off fireworks in rainy and windy weather, specifying wind speed and rainfall conditions unsuitable for use, explaining that damp fireworks are prone to misfires and explosions; strong winds alter trajectories and ignite nearby combustibles, while providing correct handling procedures for storage and postponement during adverse weather.

Firing is completely prohibited at wind speeds of 4 Beaufort scale or higher; any rainy weather (light, moderate, or heavy rain) is not recommended due to significantly increased risks. Only calm, clear, dry conditions without rain or snow are suitable for safe fireworks use. Major meteorological standards prohibiting firing in windy conditions: when wind reaches 4 Beaufort scale (capable of moving branches and continuously blowing paper on the ground), all fireworks must be stopped. Fireworks trajectories become uncontrollable, with sparks spraying randomly and injuring people; flower pots, sparklers, and aerial shells are blown off course by wind, with high-temperature embers sweeping toward crowds, easily causing facial and eye burns; shell bursts change landing points due to wind, exploding at close range above crowds, with flying fragments causing injuries. High-rise fires are highly likely: wind blows burning paper scraps and hot embers toward residential building walls, air conditioner outdoor units, balcony clothes, and dry grass in green belts, igniting combustibles quickly, making high-rise fire suppression extremely difficult. Fuse burning speed increases, leaving insufficient time to evacuate: strong winds continuously blow on fuses, accelerating their burn rate, significantly shortening the originally reserved safe evacuation time, causing fireworks to detonate before reaching a safe distance.
