India is experiencing its first sustained period of above-normal heat since July, marking a shift from a relatively mild summer in 2025. A rainy monsoon season had previously kept daytime temperatures lower than usual, with heat waves being short-lived and geographically limited. However, in the week ending September 25, the country's average maximum temperature remained above normal for seven consecutive days, a trend not observed since late July. On six of those days, the temperature deviation exceeded 0.2°C, a threshold not crossed since mid-June.
