Will Fireworks Work in the Rain? Here’s What You Need to Know

Let’s face it — this is the UK. If you wait for perfect weather to set off fireworks, you’ll probably still be waiting when the next ice age rolls in. So, what’s the deal with fireworks and rain? Do you need to call it all off if the heavens open, or is there still hope of lighting up the soggy skies?

Spoiler alert: fireworks and rain can mix — if you’re smart about it.

How Rain Affects Fireworks

Fireworks might look like simple cardboard tubes, but inside they’re a finely tuned cocktail of chemicals and fuses designed to ignite, launch and explode in all the right ways. Water, predictably, is their sworn enemy.

If fireworks absorb too much moisture:

• They may not light properly

• Fuses might fizzle out before doing their job

• The colours and effects could be duller than a wet weekend in Wigan

But don’t bin your display plans just yet — a bit of rain doesn’t have to ruin the party.

The Type of Firework Makes a Difference

Not all fireworks are created equal when it comes to rain resistance:

• Ground-based fireworks like fountains, mines and barrages tend to cope better with drizzle since they stay on terra firma.

• Aerial fireworks like rockets and roman candles can be more vulnerable as they’re exposed to more of the weather on the way up.

That said, higher-quality fireworks (like the ones we stock here at Epic Fireworks, just saying) are built tougher, with better casing and construction to keep that precious powder dry.

Light Rain vs Monsoon — Does Intensity Matter?

Absolutely. A bit of light drizzle? No problem. Your clingfilm-wrapped fireworks (more on that below) will handle it.

But if the rain’s coming down sideways, you might want to postpone. Nobody enjoys watching a damp squib in a monsoon, and besides, nobody likes soggy spectators.

Pro Tips for Firing Fireworks in the Rain

1. Keep Your Fireworks Bone Dry Until Showtime

Store them indoors or in a waterproof container until you’re ready to go. Moisture creeping in early is a sure-fire way to wreck your night.

2. Wrap Fireworks in Clingfilm

This is an old-school but genius trick. Wrap each firework in a layer of clingfilm — including the fuse — so the moisture stays out but the ignition still works.

Worried about lighting through the clingfilm? Don’t be — because that’s where portfires come in…

3. Use Portfires or a Turbo Lighter

Portfires are like the SAS of firework lighting — windproof, waterproof, and burns long enough to get the job done even in less-than-ideal weather. They’ll cut through clingfilm like a hot knife through butter.

Alternatively, a turbo lighter with a jet flame can work wonders too.

4. Cover Your Setup with Tarpaulin

If you’re setting up ahead of time, a sheet of tarp or waterproof covering can help keep everything dry until you’re ready to light up. Just remember to remove it before lighting — no one wants a melted mess.

5. Consider a Professional Display

For big events or displays where the weather could be a dealbreaker, hire the pros. Professional pyrotechnicians come prepared with weatherproof kit, specialist techniques, and a backup plan.

Don’t Let the Weather Rain on Your Parade

Sure, fireworks and water don’t mix naturally, but with a bit of preparation and the right kit, you can still have a cracking display — rain or shine.

Just remember: keep them dry, use portfires, and don’t be a hero if it’s tipping it down — wait for a break in the rain if you can.
