NEW DELHI, April 1, 2025 — Delhi residents have already endured unseasonal heat through the first quarter of the year, and experts warn the worst is yet to come. With March 2025 registering 2.4°C above normal temperatures, it has become the hottest March in three years, raising serious concerns for the weeks ahead.
Hottest March in Recent Memory, Temperature Hits 35°C
According to data from the India Meteorological Department (IMD), Delhi’s average maximum temperature in March stood at 32.3°C, compared to the usual 29.9°C. On Monday, March 31, Safdarjung Observatory recorded a maximum of 35°C, 2.4°C above normal. In contrast, night temperatures remain relatively comfortable with a low of 13.8°C, thanks to clear skies.
This March was the hottest since 2022, when the monthly average was even higher at 33.4°C. Earlier, both January and February had also seen temperatures exceeding the norm by 1°C and 2.5°C, respectively.
The key culprit? Weakened Western Disturbances, which typically bring periodic rain and snow to North India. This season, they remained subdued, resulting in minimal rainfall and low atmospheric humidity — ideal conditions for rising heat levels.
Heatwave Likely to Intensify in April
Meteorologists now warn of a steep temperature rise in the first week of April. Forecast models suggest that maximum temperatures may reach up to 38°C in Delhi by next week — a sharp spike that could pose health risks, especially for the elderly and those with pre-existing conditions.
Citizens are advised to take precautions, stay hydrated, and avoid direct sun exposure during peak afternoon hours.
Air Quality Shows Significant Improvement
Despite the scorching heat, Delhi has recorded its best air quality for January to March in five years, according to the Commission for Air Quality Management (CAQM). The average Air Quality Index (AQI) for Q1 2025 was 231, marking a significant improvement over past years:
-
2024: 250
-
2023: 240
-
2022: 241
-
2021: 278
Notably, no single day in 2025 saw AQI levels breach the 400 mark, which falls under the “severe” category. In comparison:
-
2021: 6 days over AQI 400
-
2022: 1 day
-
2023: 3 days
-
2024: 3 days
In the first quarter of 2025, Delhi saw 36 days with AQI under 200 (moderate or better), an encouraging sign compared to previous years.
The CAQM attributed the positive trend to favorable weather patterns and multi-agency pollution control measures, including stricter emissions regulation and expanded green zones.
What the Numbers Mean: AQI Categories

0–50: Good
-
51–100: Satisfactory
-
101–200: Moderate
