Delhi recorded its hottest day of the year on Tuesday (June 11) as the mercury climbed to 43.8°C at Safdarjung, the city’s base station, four degrees above normal.

The "real-feel" temperature surged to 47.7°C, pushing more regions under the grip of an intense heatwave. The India Meteorological Department (IMD) has issued an orange alert for Wednesday, with the sweltering conditions expected to persist.

According to IMD weather scientist Krishna Mishra, heatwave conditions were recorded in Lodhi Road, Ridge, and Ayanagar, with Ayanagar logging the highest maximum at 45.5°C. Other areas such as Pitampura (44.8°C), Palam (44.6°C), Ridge (45°C), and Lodhi Road (43.6°C) also reported scorching temperatures.

The IMD defines a heatwave as a maximum temperature of 45°C or more, or when temperatures exceed 40°C and are 4.5°C above normal. By this criterion, three city zones officially recorded heatwave conditions.

The combination of dry, hot westerly winds and low humidity (24%–48%) amplified the discomfort. Tuesday overtook Monday's 43.4°C to become the hottest day of the season, with May 16's 42.3°C now ranking third.

IMD Forecast For Delhi

Looking ahead, no significant relief is expected before June 13, when moisture-laden winds from the Arabian Sea and Bay of Bengal may trigger thunderstorms and rainfall across the northwestern plains. Isolated relief may arrive in parts of Delhi by Thursday (June 12), while eastern Uttar Pradesh and Uttarakhand could begin seeing cooling showers from June 11.

Until then, temperatures will likely hover around 44–46°C, with gusty winds up to 40 km/h expected to add to the discomfort.
