The Longest Day: Heat

The episode introduces the groups most at risk from extreme heat, focusing on their daily experiences. It follows schoolchildren in Indonesia and Singapore and slum‑dwelling residents in Delhi, in these cities, highlighting how rising temperatures affect their health, education and living conditions.

The Longest Day: Heat is a stand‑alone television programme that forms part of the broader The Longest Day series. Classified as a one‑off, the show concentrates on the subject of extreme heat and its impact on people’s lives. Its format is that of a single, self‑contained episode rather than an ongoing series, allowing it to focus tightly on a specific issue. In this particular episode the narrative turns its attention to the groups most at risk when temperatures climb. Viewers are introduced to schoolchildren in both Indonesia and Singapore, as well as to the inhabitants of the slums in Delhi, each of whom experiences heat in a uniquely challenging way. The segment on the Indonesian and Singaporean pupils follows their daily routines, highlighting how rising temperatures affect their school environment, learning conditions and overall wellbeing. By presenting their experiences, the programme underscores the vulnerability of children who must navigate education and play under increasingly harsh climatic circumstances. The focus then shifts to Delhi’s slum‑dwelling communities, where the episode documents how heat compounds the already difficult living conditions in these densely populated areas. It captures the day‑to‑day realities of residents who contend with limited shelter, scarce resources and the relentless rise in temperature, illustrating the profound effect that extreme heat can have on the most marginalised sections of society.
