'Delhi's Cleanest July In A Decade': Capital Breathes Easy With AQI In Rare 'Satisfactory' Phase
On Saturday, Delhi recorded an Air Quality Index (AQI) reading of 91 at 9 am, placing it within the 'satisfactory' range. The reading on July 23 had dropped to 67
Delhi, frequently plagued by intense air pollution, experienced a notable and much-needed improvement in air quality this July, with the AQI briefly reaching the 'satisfactory" category.
On Saturday, Delhi recorded an Air Quality Index (AQI) reading of 91 at 9 am, placing it within the 'satisfactory" range. Even more remarkable was the reading on July 23, when the AQI dropped to 67, also classified as 'satisfactory" by the Central Pollution Control Board (CPCB). According to CPCB standards, an AQI between 0 and 50 is considered 'good'", while 51 to 100 is 'satisfactory", indicating minimal breathing discomfort for sensitive individuals.
This improvement starkly contrasts with Delhi's usual high pollution levels, especially during winter when the AQI often reaches 'severe" or 'very poor" categories. The ongoing monsoon season plays a crucial role in this change. Rainfall helps wash away particulate matter and pollutants, while increased wind speeds disperse residual pollutants, contributing to cleaner air.
Historically, July has generally seen better air quality in Delhi compared to the post-monsoon and winter periods. Recent data suggests this July might be one of the cleanest in a decade, with an average AQI significantly lower than in previous years. Alongside the monsoon, consistent efforts by various civic agencies in pollution control, including enhanced street sweeping and landfill management, have helped maintain these improved levels.
The brief period of 'satisfactory" air quality offers a glimpse of what cleaner air feels like in a city accustomed to smog and haze.

Why is the air quality so bad in Las Vegas today? These neighborhoods have 'unhealthy' AQI
Several neighborhoods in Las Vegas, including Downtown, Angel Park, and Summerlin North, reported 'unhealthy' air quality levels on Monday, with hazy, smoky skies particularly affecting the western part of the valley. Las Vegas residents are reporting poor air quality.(UnSplash) What's causing the poor air quality? The poor air quality is primarily due to smoke drifting from the Gifford Fire burning near Santa Maria, California. Wildfire smoke has spread into the Las Vegas Valley, reducing visibility and increasing fine particulate matter (PM2.5) in the air. Current air quality readings As of 11 a.m. PDT, the average Air Quality Index (AQI) in Las Vegas stood at 184, which falls into the 'unhealthy' category according to AirNow. The worst AQI readings have been recorded in the following areas: Downtown Las Vegas – 184 AQI · Unhealthy Angel Park – 171 AQI · Unhealthy Summerlin North – 167 AQI · Unhealthy Rancho – 165 AQI · Unhealthy AirNow warns, 'Some members of the general public may experience health effects; members of sensitive groups may experience more serious health effects.' Residents react to the smoky skies Many Las Vegas residents have taken to social media to express concern over the conditions. One person wrote on Facebook, 'Be careful out there Las Vegas that Grand Canyon fire is filling the air with smoke.' Another wrote, 'This is smoke, you can't see the mountains - our air quality is bad here in the Vegas. We need some wind - can I request a lake wind from WI/MN please - to blow it out of the Valley.' A third person reported, 'It is smoky out there, Vegas peeps, worse now than early this morning (I can even smell it now). If you're elderly or have respiratory issues, please consider staying indoors as much as possible. The usual strip view is completely smoky.' Another resident reported, 'Unbelievable! This is the air quality in in Las Vegas today! No wonder I felt so stuffy and having a hard time breathing this morning! Yikes!'
