Kolkata residents were greeted by a bright and sunny morning on Saturday, December 6, 2025, offering perfect weather for weekend plans. However, the clear skies come with a cautionary note, as the city grapples with the aftermath of severely polluted air recorded just a day earlier.
Today's Pleasant Weather Conditions
The day began with a cool morning temperature of 14.6°C, setting a comfortable tone. Meteorologists forecast the mercury to climb to a pleasant maximum of 27.1°C under clear skies. With an average day temperature around 20.4°C, low humidity at 33%, and gentle winds up to 16.6 km/h, conditions are highly favourable for outdoor activities.
There is absolutely no chance of rain, making it an ideal day for markets, parks, and family outings. The evening is expected to be slightly cooler, perfect for a relaxed stroll. Steady sunshine is predicted throughout, with no significant hourly changes anticipated.
Yesterday's Severe Air Pollution Alert
In stark contrast to today's sunshine, Friday, December 5, presented a serious environmental health challenge. The city's air quality was recorded in the 'severe' category with an alarming AQI-IN index of 326.
The primary pollutants driving this hazardous reading were fine particulate matter: PM2.5 at 165 µg/m³ and PM10 at 207 µg/m³. Additionally, carbon monoxide (CO) levels were significantly elevated at 559 µg/m³. Such severe pollution levels are known to cause respiratory distress, eye irritation, and reduced visibility, posing risks especially to children, the elderly, and those with pre-existing conditions.
Health Advisories for Residents
While today's breezy weather may help disperse some pollutants, health experts advise continued vigilance. For those venturing out, especially during peak traffic hours, wearing a protective mask in crowded or high-traffic areas is strongly recommended.
For outdoor exercise, the early morning or late evening hours are considered safer to avoid both the afternoon sun and potentially higher pollution concentrations. When outdoors, carrying sunglasses and applying sunscreen is advisable due to the strong sunshine.
Weekly Forecast and Air Quality Outlook
The good news for Kolkatans is that the pleasant, dry weather is set to continue. The weekly forecast indicates consistently warm days with temperatures hovering between 27°C and 28°C, and comfortable nights with lows of 14°C to 16°C.
No rainfall is predicted for the coming days, and humidity is expected to stay moderate. Specific days like December 10 and 12 are forecast to be particularly warm, with highs of 28.6°C and 28.4°C respectively, under clear skies.
Importantly, the clear and windy conditions are expected to aid in a gradual improvement in air quality over the week. Yesterday's AQI of 326 is projected to be the peak for this period, offering some relief in the days ahead.
