Weather conditions exert a more significant influence on UK grocery sales than major sporting events like the World Cup, according to Tesco chief executive Ken Murphy. While retailers often bank on tournament-driven spending, Tesco’s latest financial data shows that a rainy spring dampened overall growth, overshadowing the temporary sales spikes generated by football fixtures.
Why weather outpaces football for grocery retailers
Sunshine is the primary driver of consumer grocery spending, as it encourages households to congregate, celebrate, and increase their food and drink purchases, according to Ken Murphy. Despite the cultural excitement surrounding international football tournaments, the sustained impact of poor weather proved to be a more substantial factor in Tesco’s quarterly performance.

Data from Tesco illustrates this contrast: while the chain’s “Whoosh” delivery service saw a 40% jump in orders during specific England match nights, these gains were localized. In comparison, the broader trend of a rainy spring led to a deceleration in overall sales growth. Analysts at Circana suggest that cost-of-living pressures, combined with a preference for staying at home, mean that large-scale sporting events are unlikely to trigger the massive, sustained surges in retail spending once seen in previous years.
During the recent international football fixtures, sales of Irn-Bru spiked by 50% in Scotland, while canned cocktail sales surged by 185% nationwide, proving that while weather drives the “big picture,” targeted product categories remain highly sensitive to event-based marketing.
How economic factors and inflation impact household spending
Tesco reported that comparable sales grew by 1.8% to £13.4bn in the three months ending in May, a figure that fell below the 2.3% growth predicted by City analysts. This slowdown is attributed to a combination of persistent economic uncertainty and a reduction in grocery inflation. Ken Murphy noted that as commodity prices for items like cocoa and coffee have eased, the headline inflation rate has cooled, naturally slowing the pace of revenue growth compared to previous quarters.

The retailer continues to face headwinds from the Middle East conflict, which has introduced volatility into petrol prices and energy costs. However, Tesco reports that these macro-economic fears have not yet fundamentally altered core shopping behaviors. To maintain its competitive edge, the company has extended its price-matching scheme against discounter Aldi to over 2,000 Express stores, aiming to retain price-sensitive shoppers.
What is the outlook for retail profit margins?
Tesco expects to meet its annual profit target of £3.25bn, despite a 3.2% decline in sales at its Booker wholesale arm. The retail giant remains under pressure, with shares falling 2.4% following the latest trading update. This follows a warning in April regarding a potential dip in annual profits, which would mark the first such decline since 2023.
Industry research from GlobalData and VoucherCodes projects a £267.7m boost to retail sales during the current tournament cycle, with approximately £70m expected to be spent specifically in pubs and hospitality venues. While these figures represent a substantial injection of capital, they remain marginal when viewed against the backdrop of Tesco’s total quarterly sales of £16.8bn.
Frequently Asked Questions
- Does football actually increase supermarket profits?
Research from Circana suggests that while individual product categories see high spikes, the overall uplift for supermarkets during tournaments is likely to be marginal due to current cost-of-living pressures. - Why did Tesco’s sales growth slow down?
According to the company, growth slowed primarily due to poor spring weather and a cooling of grocery inflation as commodity prices eased. - How does weather affect grocery trends?
Ken Murphy stated that sunshine prompts households to “eat together more, celebrate more and spend more,” making it a more consistent driver of sales than intermittent sporting events.
When analyzing retail stocks, look beyond “event-driven” headlines. Consistent growth is usually tied to supply chain efficiency, price-matching strategies, and long-term weather patterns rather than short-term spikes in demand during sporting events.
