On one day in late April, something very unusual happened. Every single one of the planet’s top 50 hottest cities was in just one country: India.
This is according to data compiled by AQI, the air quality monitoring platform. There is “no modern precedent,” AQI said [on its website](https://www.aqi.in/blog/world-top-hottest-cities-in-india-april-2026/). “This is not a normal April. And it demands a serious, data-grounded reckoning.”
AQI’s rankings are based on temperatures across 24 hours, including the daytime peak and the coolest point at night, as well as as other data including rainfall, wind and humidity.
