Not hot enough? Despite 42°C, why Delhi is not in top 10 hottest cities today
Parts of Delhi recorded the hottest temperatures of the season so far on Wednesday, with the mercury breaching 42C even before summer hits its official stride.
With a punishing combination of high daytime heat, low rainfall, and strong departure from normal, the capital is firmly in the grip of an early and intense heat spell. And yet it's not the hottest city in the country.
According to weather observations shared by the Indian Meteorological Department (IMD) at 08:30 am IST on April 23, 2026, the Ridge station topped Delhi's temperature charts on Wednesday, recording a maximum of 42.1C, a whopping 3.7C above normal.
Lodi Road followed closely at 40.8C, also running nearly 4C above normal. Safdarjung, Delhi's benchmark weather station, logged 40.7C, while Ayanagar touched 41.4C and Palam recorded 40.2C.
All five stations showed a 24-hour rise in maximum temperatures, indicating the heat is building steadily and showing no signs of easing.
It's hot enough that even the minimum temperatures are rising at an alarming rate; Safdarjung saw its mercury climb to 25.4C — 2.7C above normal, meaning there is little respite even at night.
Across all stations, rainfall was a flat zero.
But, as uncomfortable as Delhi is right now, it still doesn't quite make the cut for the world's top 10 hottest cities.
According to AQI.in's live weather ranking, India currently dominates the global heat charts, with 19 of the world's 20 hottest locations recorded within the country — but the cities topping those charts are concentrated in Bihar, Odisha, West Bengal, and eastern Uttar Pradesh, not the capital.
Delhi, despite its searing heat, is running cooler than the most extreme pockets of the country right now.
Varanasi in Uttar Pradesh was recording temperatures of 44C under sunny skies, placing it among the hottest cities in the country right now, according to AQI.in's live hottest cities rankings at 12:29 pm on April 23.
The city's geography makes it particularly vulnerable.
Located in the vast, landlocked Gangetic plain, Varanasi has little topographic relief to buffer hot, dry winds blowing in from the northwest.
Unlike coastal cities that benefit from sea breezes, or hilly towns that cool at night, Varanasi bakes through the day and offers little escape after dark.
The IMD has warned that heatwave conditions are likely to persist through April 24, with maximum temperatures expected to climb further in several regions, making the coming days a grim wait for residents of one of India's oldest and most revered cities.
What April's heat has made abundantly clear is that India's summer of 2026 is not arriving gradually and simmering to peak. It has arrived with soaring heat and is only expected to get worse.
From Delhi's Ridge to Varanasi's ghats, from Odisha's coal belts to Bihar's river plains, the country is contending with a heat event that is both widespread and intense.
For city dwellers, informal workers, and rural communities alike, staying indoors during peak afternoon hours, staying hydrated, and watching for official alerts is the best way to weather the heat.
