New Delhi: The India Meteorological Department (IMD) has issued a heatwave alert for the Delhi-NCR region, warning of a sharp rise in temperatures over the coming days, with mercury expected to cross the 40-degree Celsius mark.

Alongside the intensifying Delhi heatwave conditions, worsening air quality continues to pose a serious public health concern across the National Capital Region.

Hottest day of the season in Delhi

Thursday was recorded as the hottest day of the season so far in Delhi-NCR.

Key temperature readings included:

  • Safdarjung: 40.3°C (3.4°C above normal)
  • Lodhi Road: 40.1°C
  • Palam: 39.4°C
  • Ridge: 41.4°C

These readings signal an early onset of peak summer conditions in the capital.

On Friday, Delhi recorded a maximum temperature of 37°C and a minimum of 21°C, with clear skies expected to continue over the coming days.

IMD forecast: Temperatures to rise further

According to the IMD weather forecast:

  • April 18: Up to 38°C
  • April 19–20: Around 39°C

Air quality in the ‘very poor’ category across NCR

In addition to rising temperatures, Delhi-NCR air pollution levels remain a major concern, with several areas recording hazardous Air Quality Index (AQI) readings.

  • Bawana (Delhi): 310 AQI
  • Anand Vihar: 268 AQI
  • Ashok Vihar: 281 AQI
  • Aya Nagar: 191 AQI

In neighbouring regions:

  • Greater Noida (Knowledge Park-V): 368 AQI (very poor)
  • Noida Sector-116: 312 AQI (very poor)
  • Ghaziabad Loni: 387 AQI (worst in NCR)
  • Indirapuram: 334 AQI

AQI levels above 300 fall under the ‘very poor’ category, posing significant risks of respiratory illness, especially for children, elderly citizens and those with pre-existing conditions.

Health advisory for residents

With the combined Delhi heatwave and air pollution stress, health experts have advised residents to:

  • Avoid prolonged outdoor exposure
  • Stay hydrated throughout the day
  • Use masks in high pollution zones
  • Limit morning and evening outdoor activities

Authorities have warned that continued dry conditions and stagnant air could further worsen pollution levels in the coming days.
