Extreme heat in Hanoi
A fast-growing northern capital whose power and water strain together in the heat.
Heat type. Mostly humid heat, in a hot, wet summer.
Heat action plan No published city heat plan found
No city heat action plan found. From 2018 to 2021 the Viet Nam Red Cross ran an early-action plan for heatwaves in 15 of Hanoi’s wards, triggered by a heat-index forecast.
Vicious cycles the evidence ties to Hanoi
| Cycle | Why here | One action that breaks it |
|---|---|---|
| The energy–water loop | In May and June 2023 heat drove demand up as hydropower reservoirs ran low; blackouts in the north cost about US$1.4 billion. | Power that doesn’t need water |
| The global cooling loop | Southeast Asia’s air conditioners could rise from 40 million to 300 million by 2040. | Clean, efficient cooling |

Four questions for Hanoi’s heat plan
- Is it funded, with a named owner?
- Does it assess who is most vulnerable, and where they live?
- Does it have legal backing, so departments are required to act?
- Does it count indoor and night-time heat, not only daytime highs?
