Heatwave Wedding Survival Guide

British summers used to mean planning around rain. Now you also have to plan around 32 degrees and a cloudless sky, because heatwaves have become a genuine feature of June, July and August rather than a freak event. A hot day is lovely until it isn't, and there's nothing romantic about a guest fainting during your vows or your buttercream sliding off the cake. So if there's any chance your day could be a scorcher, build a few sensible plans now.

Shade is the single most important thing

Heat plus direct sun is what does people in. If your ceremony or drinks reception is outdoors, you need somewhere for guests to get out of the sun, and you need it before the day, not improvised on the morning.

Talk to your venue about what shade exists naturally: trees, a covered terrace, the side of a building that's shadowed by mid-afternoon. If there isn't enough, hire it. A few large parasols, a stretch tent or a pergola can transform an exposed lawn. For the ceremony itself, consider angling the seating so guests aren't squinting into the sun for twenty minutes, and offer paper fans or parasols on the chairs.

One small mercy: an outdoor ceremony in genuine heat is better kept short. Nobody wants forty minutes of readings when it's 30 degrees. Trim it.

Water, everywhere, all day

This is the cheapest and most effective thing you can do, and couples still forget it. People drink fizz and cocktails at weddings and quietly dehydrate in the heat without noticing.

Set out water properly:

• A self-serve water station with cucumber or lemon, refilled through the day
• Jugs of water on every table, not just wine
• A bottle of water at each place setting during the ceremony if it's really hot
• A nod from your toastmaster or MC reminding people to drink

If you can stretch to it, a few simple non-alcoholic options at the bar (an alcohol-free spritz, iced tea, lemonade) give people something to reach for that isn't another prosecco in the sun.

Dress for the weather, and tell your wedding party to

A three-piece wool suit at 31 degrees is a punishment. If you suspect heat, steer your wedding party towards lighter fabrics: linen, cotton blends, an unlined or half-lined jacket. Groomsmen can lose the jacket and waistcoat for the reception without anyone minding. For the couple, a heavy structured gown might look incredible and feel unbearable by 4pm, so factor comfort into your fittings.

Tell guests too. A line on your wedding website like "the day will be largely outdoors, so dress for sunshine and bring a hat" genuinely helps people pack. Build The Day lets you add weather and what-to-wear notes alongside the venue details, so guests aren't guessing.

A timeline that dodges the worst of the heat

Across most of the UK, the hottest stretch of a summer day runs from roughly 1pm to 4pm. If you've got flexibility, you can work with that.

Pushing the ceremony slightly later or moving the bulk of photos to the softer light of early evening kills two birds: more comfortable guests and better photographs.

The bits that physically melt

Heat is hard on the details. Flowers wilt, candles bow over, and buttercream and chocolate ganache do not survive a warm marquee. Talk to your suppliers honestly about the forecast.

Florists can choose hardier blooms and keep arrangements cool until the last moment. For the cake, ask your baker about heat-stable options: fondant and ganache hold up better than soft buttercream, and you can keep the cake somewhere cool until it's cut. Don't leave it sitting in a sunny window for the photos.

Makeup needs a different approach in heat too, so flag it at your trial. A setting spray and a longwear base make the difference between glowing and sliding.

Look after the vulnerable guests

Heat hits some people much harder. Keep an eye on elderly relatives, anyone pregnant, and the children, who'll happily run around in full sun until they overheat. Reserve the shaded seats for the people who need them most, have sun cream available, and put a small bottle of factor 50 and a few plasters in your wedding-day kit. A quiet, cool indoor room people can retreat to is worth its weight in gold.

A hot wedding can be glorious, all long golden evenings and bare shoulders and cold drinks. The couples who pull it off aren't lucky, they just planned for the heat the way previous generations planned for the rain. Sort the shade, the water and the timeline, and the sunshine becomes the gift it should be.
