City dwellers in France are increasingly visiting air-conditioned public spaces to escape extreme heat during ongoing heatwaves [1].

This trend, described as "AC surfing," highlights a critical gap in residential infrastructure as temperatures rise. While commercial zones offer relief, the lack of cooling in private residences forces citizens to rely on businesses and public venues to avoid heat-related illness.

Public venues such as cinemas have become primary destinations for those seeking respite. Guillemette Faure said the phenomenon is a "full house at the cinema for two hours and 40 minutes of AC" [1].

The rush to these spaces is driven by a stark disparity in cooling availability. Approximately two-thirds of offices in France are equipped with air conditioning [1]. In contrast, fewer than one in four private homes have such systems [1].

This imbalance creates a cycle where residents spend their working hours in climate-controlled environments but struggle to find similar relief at home. As a result, the demand for public air-conditioned spaces spikes during peak heat events, turning leisure activities into survival strategies.

The reliance on public infrastructure for cooling reflects a broader challenge in urban planning. Many French homes were not built with modern cooling needs in mind, leaving a significant portion of the population vulnerable during the summer months [1].

“Full house at the cinema for 2 hours and 40 minutes of AC”

The rise of 'AC surfing' underscores a systemic vulnerability in French residential infrastructure. The gap between commercial cooling—where 66.67% of offices are equipped—and residential cooling indicates that private housing has not kept pace with rising global temperatures, shifting the burden of public health and heat mitigation onto the commercial sector.
