Heatwaves in the French On-Trade: What Seven Days of Extreme Heat Reveal About Beverage Sales

Do rising temperatures automatically boost beverage sales in cafés, hotels and restaurants? Sell-out data observed during the June 2026 heatwave tells a much more nuanced story.
Between 22 and 28 June 2026, France experienced a particularly intense heatwave, with temperatures peaking on 24 and 25 June. To measure its actual impact on out-of-home consumption, Fyre compared sales during this period with those recorded during a reference week in the same month, from 8 to 14 June.
The comparison was carried out across the same outlets during both periods, helping to isolate the impact of the weather on sales volumes as accurately as possible.
The conclusion is clear: in just seven days, the structure of beverage consumption in the French on-trade market changed significantly. However, contrary to a commonly held belief, the heat did not lead to an overall increase in activity. Instead, it caused a major shift in demand between different beverage categories.
Hot beverages experience a sharp decline
Unsurprisingly, hot beverages were the first categories to be affected.
During the heatwave week, hot chocolate volumes fell by 49%, tea by 37% and coffee by 26%.
The decline in coffee is particularly significant. It is the second-largest beverage category in the French on-trade market by volume. In just one week, its share of total beverage sales dropped from 22.5% to 17.7%, representing a loss of 4.9 percentage points.
In other words, almost one-quarter of coffee volumes disappeared within a matter of days.
This development demonstrates how exposed even a category deeply rooted in consumption habits can be to weather fluctuations. It also raises the question of offer adaptation. Iced coffee, for example, is still relatively marginal in many French outlets, even though it could provide an alternative when seasonal demand for hot beverages falls.
For coffee roasters and outlet operators alike, weather should therefore not simply be regarded as an external and unpredictable factor. It can become a variable to consider when managing stocks, planning commercial activities and developing new offers.
Water and soft drinks capture most of the shift
At the other end of the spectrum, categories associated with hydration and refreshment recorded substantial growth.
Water volumes increased by 36% during the week analysed. Dairy and plant-based drinks rose by 33%, syrups and concentrates by 26%, and soft drinks by 18%.
These were the true winners of the heatwave.
The results reflect a rapid shift in consumer needs. When temperatures become extreme, hydration naturally takes priority. Customers turn towards beverages perceived as lighter, more refreshing and easier to consume throughout the day.
For brands and outlets, this shift represents an opportunity, provided the right offer is available at the right time. Product visibility, chilled availability, menu placement and staff recommendations can all strongly influence the ability to capture this demand.
A heatwave may therefore require a rapid reallocation of stocks and commercial visibility, sometimes within only a few days.
Beer remains resilient, but does not truly benefit from the heat
Beer probably delivers the most counterintuitive result in the analysis.
During the heatwave week, it gained 1.2 percentage points of market share within total beverage sales. Yet its volumes remained almost entirely stable, changing by only −0.3%.
Beer did not genuinely grow. It simply proved more resilient than the other alcoholic beverage categories.
At the same time, wine volumes fell by 25%, while spirits declined by 14%. The increase in beer’s market share was therefore mainly driven by the decline of other beverages, rather than by an increase in its own sales.
This distinction is important for brewers and distributors. An increase in market share can create the impression that a category is enjoying positive momentum. However, without analysing volumes, this interpretation can be misleading.
In this case, beer gained relative weight but did not generate additional consumption.
This example highlights the need to combine several indicators when interpreting performance, including volume growth, market share, revenue, average price and the overall development of the category.
The heatwave redistributes sales without creating additional consumption on french on-trade
The main lesson from this analysis concerns the market as a whole.
Despite the strong growth of water and soft drinks, total beverage volumes fell by 5.5% during the heatwave week.
The gains recorded by refreshing beverage categories were therefore not sufficient to offset the losses in coffee, tea, hot chocolate, wine and spirits.
Extreme heat does not automatically stimulate consumption in the on-trade market. It changes customer choices, but may also negatively affect footfall, consumption occasions and the number of drinks ordered.
When temperatures become difficult to tolerate, some consumers may avoid terraces during the hottest hours, spend less time in outlets or choose a single hydrating drink rather than a meal accompanied by several beverages.
A heatwave should therefore not simply be seen as an automatic commercial opportunity for the beverage sector. Its impact varies depending on the category, time of day and type of outlet.
How can industry players anticipate these changes?
The data provides several operational insights.
For hot beverage suppliers, weather-related risk can be both rapid and significant. Adapting the offer through cold, seasonal or customisable recipes could help limit part of the decline.
For brewers, the findings challenge the assumption that beer automatically benefits from high temperatures. The category remains resilient, but does not necessarily generate additional volumes.
For water and soft drink brands, a heatwave creates highly dynamic demand. The priority is therefore to ensure product availability, prevent stockouts and strengthen visibility when demand accelerates.
For outlet operators, anticipating a period of extreme heat primarily means adjusting stocks, menus and recommendations quickly. It may be relevant to highlight refreshing beverages, revise order quantities or offer cold alternatives to drinks traditionally consumed hot.
Finally, for the industry as a whole, these findings underline the importance of monitoring actual sales with sufficient granularity. Monthly averages or data delivered several weeks after an event do not always make it possible to identify such rapid changes.
Moving from intuition to the observation of actual sales
The impact of weather on consumption is often discussed through broad assumptions: “when it is hot, beverage sales increase” or “beer always benefits from summer weather.”
Sell-out data makes it possible to move beyond these intuitions.
By analysing actual till receipts category by category, it becomes possible to understand what is growing, what is holding steady and what is declining. This gives brands, distributors and outlet operators the ability to adapt their decisions more quickly.
The June 2026 heatwave illustrates this perfectly. In seven days, consumers did not simply purchase more cold drinks. They fundamentally reorganised their choices, to the detriment of several major categories.
In a market as fragmented and sensitive to external events as the on-trade sector, the ability to observe changes quickly represents a strategic advantage. It makes it possible to adjust stocks, activations and offers according to what is actually happening in outlets, rather than relying solely on habits or preconceived ideas.
Methodology Heatwave French On-Trade
This analysis is based on Fyre sell-out data from actual till receipts in France.
The heatwave week of 22 to 28 June 2026, with temperatures peaking on 24 and 25 June, was compared with a reference week from 8 to 14 June 2026.
For each category, only outlets that recorded sales during both weeks were included. This like-for-like approach is based on a constant panel of between 3,300 and 3,600 outlets, depending on the category analysed.
The week from 15 to 21 June was deliberately excluded because it included the Fête de la Musique, whose impact could have overlapped with the effect of the weather.
Categories represented in fewer than 50 outlets are not discussed. The results are based on the Fyre panel and have not been extrapolated to the entire French on-trade market.
Fyre aggregates till data at receipt and SKU level across eight European markets, helping foodservice and beverage industry players understand actual changes in out-of-home consumption. Heatwave French On-Trade.
