Is there a typical season for waterspouts?

Rain has multiple possible effects on fireworks. Fireworks get very hot. For example, when lit, the tip of a sparkler has a temperature of 1,200 degrees; so once lit, it would take a very heavy rain to extinguish the firework. Damp conditions from rain can hamper the lighting of some fireworks. Continue reading
