Reports also claim that temperatures will peak in Germany, Belgium as we head to the weekend.
Interestingly, heatwaves and areas impacted by climate see a change in consumer buying habits.
According to research, published this week, in Cambridge Journal of Regions, Economy and Society, called Resilience of consumer city under heatwaves, the changing climate presents new challenges by reshaping mobility and consumption patterns.
The research quoted Tian et al. (2021) which found that temperature and precipitation reshapes purchasing in Chinese convenience stores, with hot weather increasing cold drink and frozen food sales.
Inevitably beverage consumption is impacted by increased temperatures and consumers need for hydration.
Mintel told Beverage Daily that there is a history of changing consumer habits impacted by higher temperatures.
The research company said that bottled water sales were supported by spring/summer weather in 2025.
It highlighted that consumers are looking for chilled drinks and hydration in hot weather with 62% of UK adults associating bottled water with being “good for hydration” and 47% of users drinking bottled water on-the-go highlight how category performance is strongly impacted by the weather.
“Health trends emphasising hydration are helping sports drinks recover from recent volume declines. Warmer conditions in 2025 were more favourable for sports/energy drink volumes than the cool summer of 2024,” it said.
“In 2025, the UK non-alcoholic drinks retail market in general saw a weather-driven volume boost, contributing to +7.3% value sales growth.”
There is already evidence in the UK that habits are changing in the UK grocery and at home drinking.
Research from Worldpanel by Numerator found that record May temperatures drove summer spending as grocery sales rose by 2.4%.
It revealed that no-and low-alcohol drinks performed strongly, up 23% and outpacing the wider beer and cider category, which saw growth of 6%.
Syrups for water were another winner over the four weeks, up 31% year-on-year, indicating that online viral trends such as #WaterTok, the trend of mixing sugar-free syrups into water popularised on platforms such as TikTok, are filtering through to shopper behaviour.
Beverage companies see surge in sales
Suppliers are also witnessing a change in consumer habits which is driving increased volume sales.
Craig Chapman, Head of Brand at Global Brands, which owns brands such as Hooch and VK, All Shook Up and Franklin & Sons, said with the current heatwave, the UK based drinks company is already seeing a week-on week uplift of +17% through off-trade volume sales, as consumers stock up for social occasions and spend more time outdoors.
“It’s a pattern we see whenever the temperature rises – as of course we Brits always want to make the most of the sunshine when it makes an appearance,” he said.
“Across our portfolio, we’re seeing particularly strong demand for our fruity and refreshing Hooch flavours, alongside our All Shook Up canned cocktails – both of which offer convenient, ready-to-serve formats, making them ideally suited to spontaneous summer occasions.”
Adagio Teas said it has seen a “meteoric rise” in iced tea sales boosted by the UK heatwaves in May and June.
Monthly figures from the direct-to-consumer premium tea company reveal that in May iced tea sales were up 80% on April, while June’s figures are already up 83% on May’s data.
May’s iced tea sales figures were well above average for the UK arm of the US-based company, as it normally spikes in June as result of the improved weather and awareness during international iced tea month.
Stepas Parulis, head of UK and EU operations, said: “The heatwaves are definitely having an impact on the sales of our iced tea products.
“We’re only just moving into the summer months, but if this trend continues, I would expect to see record sales figures this year.”
iSqueeze, who provide fresh juice machines in retailers around the UK, have seen a big surge in drinks sales as the temperature continues to rise.
iSqueeze Founder Elias Ebert: “While freshly squeezed juice and smoothies enjoy steady year-round demand, summer brings a massive operational shift. As consumers seek out healthier ways to hydrate, volume climbs by as much as 40 to 50% during peak heatwaves.”
He added:“Crucially, this isn’t just a July peak; we consistently see these summer buying habits extend well into September, and even October if the autumn remains mild.”
Consumer habits change
While, CO2 YOU, the sparkling water company and doorstep CO2 cylinder refill service, reports a clear uplift during the hot weather, with sales of CO2 cylinders up 16% and sales of its own sparkling water machine, The Bubbla, up 53% during the last week.
Senior Marketing Manager at CO2 YOU, Charlotte Fleming, said: “It’s encouraging to see that the general public has heeded warnings about the heatwave and is taking hydration seriously.”
She added: “This suggests people want cold, sparkling drinks at home, but they also want to avoid having to head to the shop to carry back heavy plastic bottles.”
While consumers are looking to hydrate in the UK they are also transforming their alcohol choices.
Hannah Boyle, Shop Manager at The Whisky Exchange said: “We’ve definitely seen an uptick in aperitivos and vermouths recently, with consumers leaning more towards lower ABV cocktails and lighter summer-style serves. Sparkling wines have also seen a boost in popularity with the warmer weather.
She added: “Some standout products have included Tio Pepe En Rama, particularly with the release of the new vintage, as well as Aperitivo Co. Venice Aperitivo, which has been performing really well as an alternative to Aperol. We’ve also seen strong interest in canned cocktails and RTDs, with Whitebox cocktails in a can doing particularly well in our shops as people look for easy-drinking and convenient summer options.”
