Heat events are becoming hotter, longer, and more frequent. Cities need to prepare for extreme heat. But what does extreme heat mean to the people?
As temperatures rise across Europe, the need to understand what constitutes extreme heat is becoming more urgent. However, what is considered an extreme scenario in Antwerp might be a typical summer day in Barcelona. To build resilient cities, we need to understand these local perceptions of extreme heat and how concerning they are perceived, not just through sensors, but through the lived experience of the residents.
That is why the UrbanAIR researchers at TU Delft are calling on you to share your experiences through a new survey on What Heat Scenarios do Different Cities Consider as Extreme?

The UrbanAIR partner TU Delft launches a comprehensive study not only across our five focus cities, Barcelona, Antwerp, Rotterdam, Paris, and Bristol, but any city worldwide.
Why your voice matters
Led by researchers at TU Delft, this survey seeks to assess the perceptions on different heat scenarios and map the level of concerns respondents have towards these extremes. By participating, you help us identify extreme scenarios that diverge or align with how cities define them. This data is critical for:
Socially-relevant Alerts: Helping cities identify extreme heat scenarios that matter most to residents, based on how people actually feel.
Planning for Different Heat Extremes: Effective heat management must be informed by the public's lived experience. Specifically, plans must address the confusing, concerning, and underestimated heat scenarios revealed by our survey data.
Cross-City Analysis: Comparing how different urban morphologies (e.g., the density of Paris vs. the maritime climate of Bristol) influence heat tolerance.
How to Participate and Support
We invite all urban residents to take part. Whether you find the summer heat manageable or a major struggle, your input is essential for accurate research.
👉 Access the survey link below by February 28th, 2026: Participation takes approximately 15 minutes. All responses are anonymous.
👉 Contact for Inquiries: If you would like to learn more about this survey and the researchers’ work, please reach out to s.l.heng@tudelft.nl
UrbanAIR: A Collaborative Effort for Healthier Cities
UrbanAIR helps European cities plan for air quality and heat resilience with precision. The research project seeks to equip cities with the insights they need to act swiftly and plan effectively in the face of climate risks. The tools are co-designed with urban teams to address real-world needs.
As such, understanding your experience with heat is a key piece of the puzzle. By supporting this TU Delft initiative, we are helping gather the evidence needed to advocate for cooler, cleaner, and more livable cities.
