Air Quality Concerns
Yesterday, Sunday, January 18, Mumbai recorded air quality that leaned into the poor category. The Air Quality Index for India (AQI-IN) was 137.The corresponding Air Quality Index for the US (AQI-US) was 157.The biggest concern stemmed from particulate matter. PM2.5 levels were recorded at 70, and PM10 levels were at 87.Both PM2.5 and PM10 levels were high enough to potentially irritate the throat and eyes. They could also trigger symptoms for individuals with asthma, allergies, or other breathing conditions.Carbon Monoxide (CO) levels were measured at 326. This contributed to the overall pollution load, particularly in areas prone to traffic congestion.“Poor” category
Recommendations for Air Quality
The air quality from yesterday can linger into the morning hours today, especially near busy roads. Sunny, dry weather, while pleasant for planning activities, does not automatically clear pollution in the same way rain can.Light-to-moderate winds are anticipated to improve dispersion of pollutants through the afternoon. Despite potential improvements, mornings can still feel stuffy in dense neighborhoods and along major traffic corridors.Individuals who noticed scratchiness or fatigue outdoors yesterday are advised to keep their activities flexible today, particularly during the first half of the day.For those stepping out early, the morning offers a pleasant opportunity for a walk. However, it is also advisable to keep a mask handy for stretches with heavy traffic.This classic Mumbai winter-sun day calls for carrying sunglasses and using light sunscreen.
Keeping water handy is also recommended, especially if planning to be out during lunchtime.Commuters, particularly two-wheeler riders, can benefit significantly from wearing a well-fitted mask on signal-to-signal routes.If planning a longer walk or a run, the late afternoon into early evening is suggested. During this time, the breeze tends to feel better, and the heat is softer.Individuals sensitive to pollution should try to avoid the most congested stretches during peak office hours.
