Rain on the day? How to weatherproof a marquee event
What rain actually does
UK marquees are made from PVC roof and wall panels designed to shed rain, and a good install keeps the inside dry in heavy downpours. Rain-related problems tend to happen around the edges: water flowing downhill under the walls, muddy ground at doorways, wet grass on the route to the toilets, and drips where two marquees join.
Planning for rain is therefore about the ground and the routes, not just the roof.
Wet weather also affects comfort. Damp air feels colder, so in spring and autumn it is worth having heating available even if the forecast temperature looks mild.
Site checks before the build
Wet weather problems are easier to prevent than to fix on the day. When the supplier visits, or when you send photos, look at how water behaves on the site.
- Walk the site after heavy rain to see where water collects or flows
- Avoid the lowest part of a garden or field for the marquee
- Check whether land drains, ditches or soakaways run near the footprint
- Look at the routes guests will use from parking, toilets and the house
- Note any gravel, paths or hard standing that could be used as walkways
- Ask whether a slight change of position or orientation would keep the marquee drier
On a sloping site, water will usually run downhill under the walls in heavy rain. The supplier may suggest a raised floor, a small drainage channel on the uphill side, or turning the marquee so entrances face away from the slope. A few minutes looking at the site in wet conditions can save a lot of trouble on the day.
Flooring that keeps guests dry
| Floor type | Wet weather performance | Notes |
|---|---|---|
| Matting on grass | Fine for light showers | Can get soggy if water runs across the site |
| Interlocking panels | Good | Lift guests just off wet grass |
| Cassette or raised timber floor | Very good | Level and dry, handles slopes |
| Carpet on raised floor | Very good | Comfortable, needs entrance matting |
On sloping or low-lying sites, a raised floor is the most reliable way to keep the inside dry if water runs across the ground.
Routes, walkways and entrances
- Covered walkways between the marquee, toilets, catering and the house
- Matting or temporary trackway on muddy paths
- Entrance canopies so doors can stay open without rain blowing in
- Doormats and spare matting inside each entrance
- Lighting on all routes, as wet ground is slippery in the dark
- Umbrellas at entrances for guests arriving from the car park
Linked marquees and gutters
Where two marquees join, such as a main marquee and a catering tent, rain can collect and drip through the join. Frame marquee systems usually have dedicated gutters or rain covers that link structures. Ask the supplier how joins are sealed and where the water will drain to, so it does not pour onto a walkway or entrance.
Lining and drapes should also be kept clear of the walls and floor edges, as fabric touching wet walls can wick moisture and stain. Ask the crew to tie back linings at doorways if they are likely to get wet.
Vehicles and wet ground
Wet fields and lawns can quickly become impassable for vans, catering trucks and guest cars. Before the event, think about where vehicles will go and how they get there.
- Ask the supplier whether they need trackway or ground protection to reach the site
- Arrange a hard-standing car park or overflow parking if the field may be too wet
- Keep catering vehicles off lawns where possible
- Have a tractor or tow option arranged for rural sites
- Agree a backup plan with the hire company if the ground is too soft to build
After a wet event, the take-down can also take longer, as panels need drying or wiping and vehicles may struggle on soft ground.
A rain plan for the day
- Check the forecast with the supplier a few days ahead
- Have walls and doors ready to close quickly
- Move any outdoor drinks reception inside the marquee or under a canopy
- Plan photos inside or under cover
- Brief a named person to check entrances and walkways during the event
- Have towels and spare mats ready for wet entrances
Rain is rarely a reason to cancel. Strong wind is a different matter, and suppliers will advise if forecast gusts mean the event needs to change.
Frequently asked questions
Will a marquee leak in heavy rain?
A professionally installed marquee in good condition should not leak through the roof, even in heavy rain. Most wet-weather problems come from water running under the walls, joins between structures and wet entrances. Raised flooring, guttering between linked marquees and entrance canopies deal with these, and a good supplier will suggest them for exposed or sloping sites.
Can a marquee go up in the rain?
Yes. Crews regularly build in the rain, though very wet ground can slow access and make anchoring harder. If the site is waterlogged, the supplier may need trackway, more time or a slight change of position. Lightning or very high winds are the conditions that usually stop work.
Do I need a raised floor if it rains?
Not always. On flat, well-drained lawns, interlocking panels or matting can cope with typical showers. On sloping or low-lying ground, or for a big wedding in an unpredictable season, a raised floor gives the most reliable dry, level surface. It costs more, so ask the supplier to price both options so you can compare.
