France beat the heat: How Michael Olise and Les Bleus defied tough World Cup conditions

World Cup weather: From Miami sizzle to San Francisco breeze

The opening round of the 2026 FIFA World Cup group stage delivered wildly contrasting playing conditions. The hottest match so far saw Saudi Arabia face Uruguay in Miami, where the temperature outside the stadium hit 32.9°C. Marcelo Bielsa's side needed a late Maxi Araujo equaliser to salvage a 1-1 draw.

Excluding games played in air-conditioned venues (Houston, Dallas, Atlanta), the second-hottest fixture was Belgium's meeting with Egypt at 31°C, which also ended 1-1. Brazil laboured to a 1-1 draw with Morocco under a 30.9°C sun in New Jersey, while Ivory Coast's 1-0 win over Ecuador (29.4°C) meant all four hottest fixtures produced fewer than three goals.

At the other extreme, Austria's 3-1 victory over Jordan took place in just 16.2°C in the San Francisco Bay Area – a 16.7°C swing from the Miami furnace. Unsurprisingly, that match saw the highest combined distance covered so far (239.6km).

"Temperatures are regularly reaching the high 20s or even topping 30 degrees, underlining the variability of the conditions."

Sky Sports research on the Premier League has shown that distance covered and sprints typically fall as temperatures rise. That pattern has largely held at this World Cup – but not for everyone.

France set the pace in challenging conditions

While heat normally saps running intensity, France refused to wilt. Didier Deschamps' side registered the second-highest distance by any team in the first round of group matches despite playing in nearly 26°C in New Jersey – almost 10°C warmer than the conditions Austria and Jordan enjoyed.

That relentless work-rate helped them blow away Senegal 3-1 in Group I, with the game breaking open in the second half. Morocco also exceeded expectations, covering more ground than the temperature would suggest in their draw with Brazil.

USA similarly outperformed the trend line, running 119.9km in their 4-1 victory over Paraguay in Los Angeles. Teams who can maintain physical output in the heat are reaping rewards.

By contrast, England enjoyed the benefit of an air-conditioned stadium for their 4-2 win over Croatia. The crucial question: can they sustain that intensity when forced into open-air venues later in the tournament?

Olise's engine and the tournament's top runners

No one embodied France's heat-beating performance more than Michael Olise. The former Crystal Palace winger, now at Bayern Munich, covered 12.6km – the third-highest individual distance at the tournament so far. Only Jordan's Noor Alrawabdeh and Ghana's Caleb Yirenkyi ran further, and both did so in significantly cooler conditions.

Olise's running power was matched by his quality. His threaded through-ball set up Kylian Mbappe's opener, helping the France captain break the all-time Les Bleus scoring record. But it was the relentlessness off the ball that separated the win.

Elsewhere, several Premier League and European stars clocked impressive top speeds. While official data is still being compiled, the early evidence suggests that squads with conditioning depth and heat adaptability hold a distinct advantage, especially in the afternoon kick-offs that define large chunks of the schedule.

Key Takeaways

• Heat suppresses goals: The four hottest games all featured two goals or fewer, proving that extreme temperatures blunt attacking fluency.
• France are physical outliers: Les Bleus ran the second most as a team in spite of 26°C heat, showing elite fitness and tactical discipline.
• Michael Olise covers ground: His 12.6km haul in tough conditions made him the tournament's third-hardest runner – and he paired it with creative end product.
• Air conditioning matters: England and others who played in climate-controlled stadia may face a reality check when they step outside.
• Variability is extreme: Teams must adapt to a 16°C difference between venues, making squad rotation and hydration strategies vital.
