Retail Under Pressure: How to Sustain Store Operations Through Multiple Heatwaves

Europe has been hit by multiple heatwaves and retail performance is showing the strain.

This summer, many parts of Europe and North America have faced not just one, but multiple heatwaves, with repeated spikes above 40°C / 100°F. As each wave arrives, so do mounting operational challenges: overstretched teams, disrupted demand, and missed sales.

At Quorso, we’ve been monitoring how repeated heatwaves impact store performance across the organization and not just at store level. From merchandising to supply chain to store ops, the patterns are clear, and they are costing retailers real revenue.

Why repeated heatwaves spell risk for retail execution

We’ve identified three recurring challenges that are emerging each time the heat returns:

Underperforming stores in heatwave zones

While categories like cold drinks, ice cream, fans, and sunscreen surge in demand, footfall in shopping centers and retail parks has declined significantly in both the UK and US during peak heat events. For example, UK footfall dropped by 11% during recent heatwaves, while in the US, major cities like Phoenix and Houston saw consumers avoid outdoor shopping altogether. In contrast, coastal and tourist-heavy areas saw increases — the UK reported a +11.4% footfall rise in seaside towns, a trend echoed in US destinations like Southern California and Florida.

Persistent readiness gaps despite multiple heatwaves

Despite earlier heatwaves, many retailers remain underprepared. For example, one large European retailer reported a 35% one-day surge in ice cream sales, yet stores ran into supply issues during peak hours – a sign that promotional and inventory planning are still lagging. In the US, similar issues were seen with cold beverage shortages and ice machine failures in Midwest supermarkets.

Operational teams stuck in reactive mode

Traditional workflows aren’t designed for fast, localized adaptation. When a heatwave hits, many teams scramble, reacting to the moment instead of acting in advance, missing short-term promotional windows or failing to adjust staffing and stock levels in time.

Weather affects more than operations – it changes how people shop

Weather doesn’t just influence logistics – it reshapes shopper behavior across regions and channels.

• Do customers stay home and order online rather than venture out in the heat?
• Does demand shift toward ready-to-eat meals, chilled beverages, salads, or BBQ items?
• Are frozen categories becoming top performers in both Europe and the US during peak heat?

According to the National Retail Federation and Planalytics, weather influences roughly 3.4% of global retail sales – equal to about $1 trillion annually.

And it’s not just about consumers. Heatwaves strain infrastructure as well, leading to refrigeration failures, stock spoilage, and reactive maintenance calls. Some supermarkets in the US and Europe using IoT-based cooling monitors saw up to 49% fewer stock losses and 40% fewer urgent maintenance calls during high-heat periods.

With Quorso, retail teams can respond dynamically to both climate and customer movement -surfacing stores where footfall is dropping, others where it’s spiking, and triggering data-led actions accordingly. This means not only protecting sales and margins, but also enhancing the customer experience – by ensuring the right products, staffing, and promotions are in place exactly where and when shoppers need them.

Creating a truly connected enterprise – from buyers to store teams

Quorso doesn’t just support the store, we help the entire retail enterprise stay coordinated and responsive:

• Buyers can use Quorso to access weather-linked sales data to increase orders of weather-relevant products like BBQ food, cold beverages, or seasonal produce.
• Merchandising teams can trigger or adjust local promotions based on Quorso alerts.
• Field and Ops leaders can see where staffing gaps or overstock risk are highest, and act quickly.

This is where Quorso becomes critical, identifying stores facing similar environmental pressures and activating precise, synchronized responses across departments.

Turning heatwave chaos into operational clarity with Quorso

At Quorso, we combine real-time weather data with granular store performance insights to group stores facing similar short-term environmental pressures, like high heat, and trigger targeted action plans.

Instead of applying a generic strategy, we help teams:

✅ Focus where it matters – prioritize stores and regions most at risk.
✅ Act while it counts – push targeted actions exactly when they’re needed.
✅ Convert weather volatility into commercial clarity – reduce missed opportunities and drive better outcomes.

This isn’t just summer. It’s a stress test.

Multiple heatwaves are no longer an anomaly – they’re a pattern. And each one exposes vulnerabilities in traditional, reactive retail models.

With Quorso, retailers can get ahead of each wave, with tailored interventions that ensure every store is ready, every department is aligned, and every opportunity is captured.

Because while the weather is unpredictable…
your operations don’t have to be.
