What heatwaves mean for summer weddings – and how to plan for one

Heatwaves have become a significant concern for summer weddings in the UK, with brides like Aimie Seale facing extreme temperatures during their ceremonies. Seale's dress kept falling off due to the 30C heat, causing her and her husband Ryan to rent a marquee and provide ice cream for their guests. This issue is becoming more common, with half of the years between 2015 and 2024 experiencing temperatures above 35C, up from one in ten.

Experts warn that the financial impact on wedding venues and businesses is soaring, with venues having to invest in air conditioning units and additional fans, which can cost thousands of pounds. The heat has also affected guest behavior, with reduced alcohol sales as people drink more water to stay cool. Flowers are another casualty, as popular choices like peonies and roses see their flowering window shrink due to water shortages and heat stress.

Rebecca, a floral designer, had to source flowers from multiple growers, incurring additional delivery costs. Wedding planners like Sarah Haywood advise couples to avoid the peak summer months, suggesting shoulder seasons such as June and September or even October, which are becoming increasingly popular. The 2026 UK Wedding Report indicates a significant rise in October weddings following hotter summers.

Marie Cavanagh, planning her July wedding, is considering the heat when selecting her attire. Stylists are also recommending lighter fabrics and innovative materials like zinc oxide to keep dresses cool. European destinations with lower temperatures are gaining popularity as UK couples look for alternative wedding locations. Wedding venues in the UK are adapting by constructing cooling measures, such as air-to-air heat pumps, to prevent bookings from dropping due to the unpredictable weather.
