Switzerland’s Euro 2025 Faces Climate Challenge: How Basel Is Adapting to Extreme Heat

As temperatures surge to unprecedented heights in Switzerland, anticipation for the Women’s Euro opening match between the hosts and Norway pulses through the city of Basel. For both locals and international fans, the boiling weather has become an inextricable part of the tournament experience—a factor affecting not just comfort, but the very way the community engages with this prestigious international event. In a country famed as much for its meticulous organization as for stunning alpine landscapes, Switzerland now finds itself balancing climate adaptation with the electric atmosphere of elite competition.

Heatwaves and Football Fervor: A New Normal?​

As of the Women’s Euro kickoff, temperatures in Basel have been forecast to spike to 35 degrees Celsius. For regions less accustomed to such heat in early summer, these conditions represent a daunting challenge. Players, staff, and especially supporters must adapt rapidly. UEFA, recognizing the risks, has implemented measures typically reserved for summer tournaments in Southern Europe—most notably, relaxing rules to allow spectators into St Jakob-Park stadium with half-liter plastic or aluminum water bottles.
This decision, lauded by many fans, underscores broader climate-driven adaptation in large-scale football. Norway supporter Lars Haloersen, reflecting a popular sentiment, called the adjustment “very nice, because it's very important to drink a lot of water, so half a litre of water per person is very nice to get in,” as he and his family sought relief in the Rhine’s iconic currents before kickoff.

The Rhine: Basel’s Liquid Lifesaver​

If stadium policy forms one official arm of coping with sweltering conditions, the Rhine River offers the city’s most beloved informal alternative. On the day of Switzerland’s awaited opener, the river banks transformed into a festival of resilience and joy. Basel residents and visitors, following the lead of well-prepared locals, stashed valuables in buoyant “Wicklefisch” waterproof swim bags and plunged feet-first into the cooling waters, a ritual colloquially known as “Reinschwimmen.” “We also have a fountain near our house and sometimes we take a dip in that to cool off, but that's about all we can do,” Basel resident David Borrowman told Reuters, as families clustered around the water’s edge.
Events like these don’t merely illustrate local ingenuity—they highlight the evolving relationship between sport, environment, and urban planning. The city’s Fan Zone, for example, featured water misters and complimentary sunscreen, recognizing that comfort and safety are foundational to an inclusive tournament experience.

Climate Change and Major Sporting Events​

The 2025 Women’s Euro is unfolding against a backdrop of escalating climate variability. Across Europe, sporting authorities face mounting pressure to factor heat risk into the DNA of event planning. Multiple studies now affirm—extreme heat events are increasing in frequency and intensity owing to anthropogenic climate change. According to the European Environment Agency, central and southern Europe have seen a marked rise in the number of “dangerous heat days” over the past two decades, a pattern projected to accelerate.
UEFA’s proactive response, allowing bottles and upgrading cooling zones, represents an evolving playbook for safeguarding public health. Yet, there remain open questions regarding the extent of preparedness for truly severe heat waves, especially given that even a well-meaning half-liter bottle is unlikely to suffice over a full match’s duration on the hottest days.

Risks and Adaptation: Strengths and Gaps​

Strengths​

• Proactive Policy Adjustment: Organizers recognized the heat threat in advance, updating stadium entry protocols and enhancing Fan Zone amenities.
• Clear Communication: Both local authorities and UEFA kept fans informed, with visible signage and volunteers providing assistance and guidance.
• Utilization of Natural Resources: The accessibility and safety features of the Rhine River enable the city to offer a free, healthy, and communal method of cooling off.

Weaknesses​

• Water Rationing Limits: While the half-liter per fan policy is a step forward, public health guidance in heatwaves often recommends 1.5–2 liters of water per person per afternoon for safety—significantly more than allowable for stadium entry. The risk of dehydration remains palpable, especially for sensitive groups.
• Unequal Access: The Rhine provides an exceptional amenity, but not all fans—especially those with mobility challenges—can take advantage. Similarly, those in the upper tiers of St Jakob-Park may still face heat stress, despite improved airflow.
• Short-Term Solutions: Neither sunscreen nor spray misters can substitute for more robust long-term action, such as schedule adjustments, shaded seating installations, or even shifting tournament dates in anticipation of climate unpredictability.

Football, Community, and Shared Adaptation​

Basel’s communal spirit shines brightest when adversity strikes. The vision of Norwegian and Swiss supporters, children and elders alike, taking the plunge into the Rhine is not just a symbol of local resilience, but a testament to football’s unifying power. For a city built along the river, water is more than a cooling resource—it is a gathering point, a social glue. Music, laughter, and the splash of feet in the water make clear: even in times of discomfort, the ritual of sport serves to bring people together.

UEFA’s Heat Action Playbook: Evolution or Patchwork?​

Across recent European tournaments, UEFA has steadily evolved its approach to weather extremes, spurred in part by player and union pressure. Cooling breaks during matches, guidelines for stadium hydration stations, and revised policies on headwear and sun protection are now increasingly standard.
Still, critics warn that adaptation is reactive and often piecemeal. Footballers’ associations and public health bodies routinely call for bigger steps. For instance, Spain’s La Liga and Italy’s Serie A have both postponed or rescheduled matches due to excessive heat in recent years—moves supported by strong union threats and medical advisories. Other leagues have experimented with shifting match times later in the evening or even to cooler months. By contrast, major tournament organizers tend to be more constrained by broadcast schedules and international coordination, making comprehensive climate adaptation more complex—and urgent.

Lessons from Basel for Future Tournaments​

The 2025 Women’s Euro in Basel may ultimately serve as a keystone event for rethinking climate resilience in European football. While the immediate measures—access to water, shade, and the liberating flow of the Rhine—proved effective for most, they raise pointed questions about future viability:

• Should match schedules be further adjusted to late evenings or even nighttime to mitigate daytime heat spikes?
• How can stadiums be redesigned to maximize shade and ventilation, particularly as legacy venues compete with new builds?
• Would allowing unlimited water bottles, or at least expanding the allowable volume, balance security with health?
• What innovations in fan-side cooling—such as distributed misting stations, wet towels, or drink refill stations—can be scaled quickly across other venues?

These are not just football questions, but increasingly, matters of urban health and resilience.

Health and Safety Versus Security​

The debate over water bottle policies serves as an illuminating case study. Stadium security experts traditionally oppose large or glass containers, citing projectile risks, while health experts call for greater flexibility during heat events. In the United States, moves by leagues like the NFL to allow empty, reusable water bottles during heat waves have been widely seen as successful compromises. European sports authorities are now charting a similar path—but often with added complexity, owing to variable stadium infrastructure and regional security concerns.
Even half-liter bottles, such as those approved for Basel’s tournament opener, walk a fine line between minimizing risk and maximizing safety. It remains to be seen—especially in a summer marked by record-breaking temperatures—if this is enough.

Fan Experience: More Than the Game​

For many attendees, the memorable moments will not be limited to the pitch. The joy of slipping into the Rhine, the camaraderie of sunscreen-sharing lines, and the sighs of relief under spray misters become woven into the fabric of the event itself. As football fans reflect on the Women’s Euro, these collective coping strategies may shape enduring memories as much as the results on the scoreboards.
From an organizational perspective, the lesson is unmistakable: planning for the fan journey must now extend well beyond the match, to recognize the full gamut of environmental hazards. This entails not just reactive policies, but new standards for infrastructure, staffing, and communication.

Data-Driven Insights: What Does Science Say?​

Peer-reviewed studies published in recent years map a worrisome trajectory for extreme heat in Europe. According to a 2024 report by the European Environment Agency, average summer maximum temperatures in Central Europe have risen by more than 1.5°C over the past 30 years, with extreme heat events in Switzerland doubling compared to the late 20th century. Medical guidelines urge organizers of sporting events to implement multilayered safety measures when temperatures exceed 32°C—a threshold likely to become ever more common.
Benefits of rapid cooling—either via water immersion or active misting—are well-documented, with evidence showing significant reductions in rates of heat exhaustion and related incidents. However, effective cooling requires not just access, but also encouragement to use the facilities, ongoing monitoring, and support for vulnerable groups.

Looking Forward: Recommendations for the Future​

In light of this year’s tournament experience, several recommendations emerge, relevant to both local organizers and international sporting bodies:

1. Rethink Venue Operations​

• Hydration: Adopt flexible, science-backed policies allowing fans to bring larger volumes of water, or at minimum, providing ample refilling infrastructure inside and near venues.
• Shade and Shelter: Invest in movable awnings, plantings, or semi-permanent structures that can be deployed ahead of major summer events.
• Medical Preparedness: Expand medical staffing and heat illness training for volunteers; provide rapid response cooling kiosks.

2. Expand Communication​

• Real-Time Updates: Equip fans with live weather alerts and practical heat safety reminders via mobile apps and venue displays.
• Clear Signage: Use internationally understood icons and multilingual instructions for hydration stations, cooling zones, and first aid.

3. Foster Inclusive Access​

• Mobility Solutions: Ensure riverside and cooling area access for those with disabilities or limited mobility.
• Distributed Amenities: Place water and shade controls evenly throughout Fan Zones and stadium tiers to serve all ticket holders.

4. Learn Locally, Scale Globally​

• Basel’s use of local waterways and the collective tradition of “Reinschwimmen” provide a model of adaptive, community-based resilience. Tournaments elsewhere—especially where natural cooling resources are absent—will need different, but equally robust, local solutions.

Conclusion: Sport at the Edge of a Changing Climate​

As the sun set over Basel’s St Jakob-Park and the Women’s Euro opening whistle blew, a new chapter opened not just for Swiss football, but for Europe’s understanding of the intersection between sport, city life, and climate challenge. This tournament, defined as much by its improvisational cooling rituals as by the thrills on the field, stands as a microcosm of adaptation in action. The strength of the Swiss and visiting fans lies not just in their passion for football, but in their readiness to invent and share, drawing on the best of tradition and innovation.
The future of major tournaments in an era of accelerating change will demand more—more science, more community involvement, and above all, more willingness to rethink old habits. Basel’s Euro story is both a cause for optimism and a call to action: to ensure that the beautiful game, in all its forms, remains a source of joy and togetherness, even as the world grows hotter.
