Delhi’s Air Quality Deteriorates Again as Rain and Thunderstorms Expected Today

By | May 16, 2025

Delhi is once again battling worsening air quality as pollution levels slip into the “poor” category. According to the Indian Meteorological Department (IMD), the national capital recorded a minimum temperature of 26.2 degrees Celsius early this morning—just slightly below the seasonal average. While this may seem like a typical pre-monsoon day, the bigger concern is the unhealthy air and its potential impact on the city’s residents.

Air Quality Index Slips to ‘Poor’

As of this morning, several parts of Delhi recorded an Air Quality Index (AQI) in the range of 201–300, which falls under the ‘poor’ category. An AQI in this range can cause breathing discomfort for people with respiratory issues and can even affect healthy individuals with prolonged exposure. Areas such as Anand Vihar, Jahangirpuri, and RK Puram saw particularly high pollutant levels.

Environmental experts warn that while Delhi is no stranger to air pollution, the onset of summer usually brings some relief. However, dust storms from Rajasthan and vehicle emissions, combined with the lack of consistent rainfall, have contributed to the latest spike in pollution.

Thunderstorms and Rain Likely to Provide Temporary Relief

There is some good news on the horizon, though. The IMD has forecast thunderstorms accompanied by light to moderate rain across the city later today. These pre-monsoon showers could help settle the dust and bring temporary relief from the high pollution levels. Winds ahead of the storm are also expected to clear out some of the pollutants trapped in the lower atmosphere.

According to meteorologists, scattered rain and gusty winds reaching up to 40 km/h may occur during the late afternoon or evening. The changing weather is also likely to bring down temperatures slightly, offering some respite from the heatwave-like conditions Delhi has been experiencing in recent weeks.

Health Advisory for Delhi Residents

With the air quality in the ‘poor’ range and weather changes expected, experts are urging residents to take precautions. Here are some recommendations for people living in Delhi today:

  • Avoid Outdoor Activities: Especially in the early morning and late evening when pollution levels tend to peak.
  • Use Air Purifiers: Those with asthma, bronchitis, or other respiratory issues are advised to use air purifiers indoors.
  • Wear Masks: If stepping out is necessary, wearing an N95 mask can help reduce inhalation of harmful particles.
  • Stay Hydrated: The combination of high temperatures and dust can lead to dehydration and fatigue.
  • Check Weather and AQI Updates: Apps and websites can help residents stay informed and plan their day accordingly.

Impact on Daily Life and Traffic

Pollution and erratic weather often go hand in hand with disrupted daily life. Low visibility due to dust and smoke has already led to traffic congestion in some parts of the city. With the IMD’s rain forecast, motorists are advised to drive cautiously, as roads can become slippery and visibility may drop further during storms.

Commuters using public transport may also face delays, particularly if heavy rainfall occurs during peak hours. Authorities have advised the Delhi Metro and DTC bus services to be prepared for potential weather-related disruptions.

What’s Causing the Spike in Pollution?

While Delhi faces poor air quality throughout the year, this sudden spike is a result of several environmental factors. Experts say the major contributors include:

  • Dust storms from the west: Dry winds from Rajasthan and adjoining areas bring large amounts of dust into the city.
  • Lack of rainfall: The absence of pre-monsoon showers until now allowed dust and pollutants to accumulate.
  • Increased vehicular emissions: With schools reopened and businesses operating in full swing, the number of vehicles on the road has significantly increased.
  • Construction activity: Ongoing construction work, both public and private, adds to the dust levels, especially when not properly regulated.

What Lies Ahead?

The IMD says Delhi could experience more rainfall in the coming days, especially with the monsoon inching closer to north India. While today’s thunderstorms might provide some short-term relief, sustained rain will be crucial for long-term improvement in air quality.

Meanwhile, the Delhi government and the Central Pollution Control Board (CPCB) are monitoring the situation closely. Authorities may consider issuing advisories or restrictions on construction and vehicular movement if the air quality worsens.

A Wake-Up Call

Today’s weather and pollution update is not just a passing news item—it’s a reminder of the urgent need for sustainable urban planning and better environmental management. Delhi’s air quality issues are not new, but with every passing year, the health risks and environmental damage become more severe.

While natural factors like dust storms and summer heatwaves are beyond human control, policies that reduce emissions, improve public transportation, and promote greener construction practices can make a significant difference.

Conclusion

As Delhi braces for a day of thunderstorms and rain, the hope is that it will bring more than just temporary relief from the heat—it might also cleanse the air, at least for a while. But unless long-term measures are implemented and enforced consistently, the city’s struggle with pollution will likely continue. For now, residents are advised to stay indoors when possible, monitor the weather and AQI updates, and take necessary precautions to protect their health.
