NEW DELHI — The national capital experienced a scorching Wednesday, March 11, 2026, as temperatures soared to 36.8°C, making it the hottest day of the season so far. The surge is part of an alarming trend this March, with the India Meteorological Department (IMD) noting that the maximum temperature was a staggering 8.4 degrees above the seasonal average.
The early heatwave-like conditions have been paired with stagnant air, keeping the city’s Air Quality Index (AQI) in the “Poor” category for five consecutive days.
1. Why is Delhi So Hot in Early March?
Meteorologists point to a lack of typical spring weather patterns as the primary culprit for the spike.
- Absence of Western Disturbances: Usually, moisture-laden winds from the Mediterranean bring cloud cover and light rain to North India in March. This year, their impact has been “negligible,” according to Skymet Weather.
- Clear Skies & Direct Sunlight: Without cloud cover to block the sun, the mercury has had a “free run.” Last Saturday already saw the earliest 35.7°C recorded in 15 years.
- Minimum Temperature Jump: Even the nights aren’t providing much cool-off; Wednesday’s minimum was 17.8°C, over four degrees above normal.
2. The Relief Forecast: Cyclonic Circulation & Rain
While the heat is intense, the IMD predicts a temporary reprieve starting this weekend.
- The “Rajasthan System”: A cyclonic circulation is expected to form over Rajasthan, pushing cooler winds into the Delhi-NCR region.
- Timeline for Relief:
- March 12–14: High wind speeds will begin to pick up.
- March 15: High chances of thunderstorms and light rain.
- March 17: Temperatures are expected to stabilize between 30°C and 33°C.
3. AQI Alert: “Poor” Air to Persist
The heat has not helped the city’s air pollution. On Wednesday, the 24-hour average AQI was 244.
- Current Status: The AQI is expected to remain “Poor” through March 14.
- Improvement Ahead: As wind speeds increase with the approaching Western Disturbance on March 15, pollutants are expected to disperse, potentially bringing the air quality back into the “Moderate” category.
