Outdoor Halloween Decorations That Survive British Weather

Outdoor Halloween decorations in Britain have to cope with a typical late October: showers, gusty wind, damp mornings and early dark. The decorations that last are the ones rated for outdoor use, anchored properly and powered safely, and the ones that struggle are indoor props left in the rain. Nothing electrical is "British-weather-proof" by default, so the trick is knowing what each decoration is rated for and setting it up to match.

What does "outdoor" actually mean on a Halloween decoration?

Quick answer

Look for three things on the product page: an IP rating, whether it's for open or covered outdoor use, and any weather warnings. An IP44 inflatable can stand out in a shower; a prop marked "indoor or covered outdoor" should stay under shelter.

An IP (ingress protection) rating has two digits. The first is protection against solid objects, the second against water. The second digit is the one that matters for rain:

Our own product listings spell this out. For example, the 10ft inflatable ghost has an IP44-rated polyester shell and comes with ground stakes, guy ropes and sandbags, but the instructions still say to avoid using it outdoors in heavy rain, snow or strong wind. That's typical: an outdoor rating means it copes with normal showers, not a storm.

Inflatable decorations: the rain and wind question

Inflatables are the most popular front-garden decoration, and wind is their main enemy rather than rain. A tall inflatable acts like a sail. Set-up makes most of the difference:

1. Pick a sheltered spot, ideally against a wall or hedge rather than in the middle of an open lawn.
2. Use every anchor supplied. Stakes go into soft ground at an angle, guy ropes should be taut, and sandbags or weights hold the base on patios where stakes won't go in.
3. Keep the fan clear. The blower needs to run continuously and must not sit in a puddle or get blocked by leaves.
4. Check the forecast. If strong wind or heavy rain is due, unplug and deflate it. It takes minutes to put back up.
5. Size for your garden. An 11.8ft (about 3.6m) ghost looks dramatic but catches far more wind than a 6ft figure in a small front garden.

You'll find inflatables from 1.2m to over 3.5m tall in our Halloween collection. Smaller mains-powered pieces such as the 6ft ghost with pumpkin (IP44, with a 3m cord, stakes, ropes and sandbags) are easier to position near a socket and near shelter.

LED lights and outdoor electrical safety

Quick answer

Use decorations made for outdoor use, plug them into an RCD-protected socket, and use only outdoor-rated extension leads and connectors. Don't daisy-chain extension leads, and keep plugs and connections off wet ground.

Electrical Safety First's garden guidance recommends using an RCD (residual current device) with all outdoor electrical equipment, only using extension leads, cables and connectors suitable for outdoor use, and never plugging one extension lead into another. An RCD cuts the power if it detects a fault, which is exactly the kind of protection you want when it's raining. If your sockets aren't RCD-protected at the fuse box, a plug-in RCD adaptor does the same job.

The NICEIC adds that a properly installed, weatherproof outdoor socket is safer and more convenient than trailing a lead from indoors, if you decorate every year.

Practical steps for a wet October evening:

• Test the RCD using its test button before you plug anything in.
• Raise connections off the ground, for example on a brick, and cover them with a purpose-made weatherproof connector box.
• Route cables where no one will trip over them, and never through a door or window that closes on the lead.
• Unravel cable reels fully before use so they don't overheat.
• Check last year's decorations for split cables, cracked plugs or damaged seams before plugging them in.

Battery-powered decorations sidestep mains cables altogether, which makes them easier to place, though their battery compartments still need keeping dry.

Animatronics: keep them under cover

Moving props with motors, speakers and sensors are the most weather-sensitive decorations. Most are designed for indoors or a covered position. For instance, our 170cm animated grim reaper is listed for indoor or covered outdoor use, runs on AA batteries, and its product page notes that its sound and vibration sensor can be set off by wind, so it's worth switching off between uses on blustery nights.

Good spots for animatronics are a porch, a covered doorway, a carport, or under a pop-up gazebo with sides. They also look more effective close to where trick-or-treaters walk up.

Pumpkins: real, artificial or inflatable?

• Carved real pumpkins start to soften and go mouldy within days in mild, damp weather. Carve them as close to Halloween as you can, keep them somewhere cool, and compost them afterwards.
• Lighting a real pumpkin: battery LED tea lights avoid the fire risk of a naked flame near costumes, dry leaves and doorways.
• Artificial pumpkins, such as resin or plastic sets, don't rot and can be reused, though lightweight ones need placing where they won't blow away.
• Inflatable pumpkins give the biggest visual impact for the least effort, with the same wind and power considerations as other inflatables.

Securing decorations against wind

• Hang lightweight pieces, such as a stainless steel pumpkin wind spinner, from a sturdy branch or bracket rather than a flimsy hook.
• Stake free-standing props and use cable ties to fix them to a fence or railing where possible.
• Weigh down anything freestanding on a patio, where stakes can't be used.
• Avoid decorations that could blow into the road or a neighbour's car if they come loose.
• Check everything the morning after a windy night.

Storing decorations after Halloween

1. Dry everything completely. Inflate fabric inflatables on a dry day, or indoors, and let them air before folding. Packing them damp is the main cause of mould and musty smells.
2. Remove batteries from props and lights so they can't leak and corrode the contacts.
3. Coil cables loosely rather than wrapping them tightly round the item.
4. Keep the stakes, ropes and sandbags with each inflatable, in a labelled bag or box.
5. Store somewhere dry, such as a loft, cupboard or a weatherproof garden storage box, rather than a damp shed floor.

What to check before buying

• Is it rated for open outdoor use, or only covered outdoor use?
• What's the IP rating, and does the listing warn against heavy rain or wind?
• Is it mains or battery powered, and how long is the cable?
• Are stakes, guy ropes and sandbags included?
• How tall is it compared with your garden and how exposed is the spot?
• Where will you store it, and how big is it once packed away?

Common mistakes

• Putting indoor props outside because it "probably won't rain".
• Leaving inflatables up and running through a storm.
• Using an indoor extension lead across a wet lawn.
• Skipping the guy ropes because the inflatable looks steady on a calm afternoon.
• Packing decorations away wet, then finding them mouldy next October.

Frequently asked questions

Can inflatable Halloween decorations stay out in the rain?

Many can cope with light rain if they're rated for outdoor use, commonly IP44. Most manufacturers still advise against using them in heavy rain, snow or strong wind, so switch off and deflate when bad weather is forecast.

What does IP44 mean on outdoor decorations?

IP44 means the item is protected against solid objects larger than 1mm and against splashing water from any direction. It suits showers, but it isn't designed for heavy rain, jets of water or sitting in puddles.

Do I need an RCD for outdoor Halloween lights?

Electrical Safety First recommends using an RCD with all outdoor electrical equipment. If your socket isn't protected by an RCD at the fuse box, use a plug-in RCD adaptor.

Can animatronic Halloween props go outside?

Check the listing. Many are designed for indoor or covered outdoor use only, which means a porch or under a canopy, away from direct rain.

How do I stop Halloween inflatables blowing over?

Use all the stakes, guy ropes and sandbags supplied, choose a sheltered spot near a wall or hedge, and deflate the inflatable when strong wind is forecast.

Planning your display

Put your weather-rated inflatables and lights in the open, keep animatronics under cover, and make sure everything electrical runs through an RCD. You can browse inflatables, animatronic props and smaller outdoor pieces in our Halloween decorations collection, and find weatherproof boxes for storing them in our garden storage range.
