Abstract
Heatwaves are no longer rare anomalies in temperate cities; they are lived, negotiated, and unevenly endured. Yet behavioural adaptation—a vital first line of defence—remains underexplored. Drawing on a sequential mixed-methods design integrating in-depth interviews (N = 21) and a nationwide survey (N = 1,849) across Dutch urban density gradients, this study shows that behavioural adaptation is less a matter of individual choice than of social, structural, and spatial constraint. Homeowners leveraged their control over private spaces to adopt both active and passive technological adjustments, achieving higher adaptation scores. Tenants, constrained by housing tenure, disproportionately relied on cultural adjustments rooted in social ties and experiential knowledge. Residents of very highly urbanised areas reported higher indoor temperatures and demonstrated the lowest adaptation scores, revealing density-driven limits to coping capacity. Gender and household composition further influenced adaptive capacity, with women and multi-person households displaying consistently stronger responses. By centring behavioural adaptation, the study identifies key barriers and exposes the mechanisms through which adaptation inequality takes shape in temperate urban settings.
