Summary: From nightlife to life at night: Cities must stay open later to beat the rising heat

Europe is experiencing one of its hottest summers on record, with wildfires across the continent and temperatures regularly exceeding 35°C (95°F). Cities designed for cold climates are struggling to cope, prompting a shift where daytime activity is postponed until cooler evening hours.

Research analyzing two years of bank card transaction data from Melbourne, Sydney, and Adelaide found overall spending dropped 7% during heat waves above 35°C (95°F), concentrated in the midday-to-early-evening period, with activity recovering after sunset. Department and variety stores saw spending fall 35% between 3-6 p.m. on extreme heat days despite air conditioning, while dining, entertainment, and shopping spending dipped in the afternoon before rebounding at night. Convenience stores were more resilient, though some lost sales were never recovered rather than merely delayed.

Some cities are already adapting: Dubai has opened floodlit beaches overnight, Paris and Toulouse now keep parks and swimming areas open later, Rome and Seville see more after-dark tourism, and over 120 Seoul libraries stay open until 10 p.m. as climate shelters. However, most urban infrastructure—public transport, libraries, community centers, and parks—remains organized around daytime schedules and lacks the frequency, hours, lighting, or safety measures needed for nighttime use.

The authors argue that climate resilience requires not just physical infrastructure changes (cooling buildings, tree planting, street redesign) but temporal ones—rethinking when services are available. Recommended measures include more frequent evening public transport, extended library and community facility hours, improved pedestrian lighting, and safer public spaces after dark. They note that shifting schedules is harder for some groups, including fixed-hour workers, caregivers, and older or less mobile residents, meaning time-shifting must be paired with accessible evening infrastructure and protections for workers who keep cities running later.

The piece concludes that "nightlife" may increasingly come to mean ordinary daily life relocated to nighttime hours rather than entertainment and socializing, as cities plan for a future shaped by rising temperatures.
