New Delhi weather today: Sunny skies, mild temperatures; AQI remains poor

New Delhi, Thursday, January 15, 2026, is set for a bright, winter-sun day with temperatures ranging from 9.6°C to 21.4°C and no rain expected. Despite the pleasant weather, yesterday’s air quality was categorized as "Severe," meaning lingering haze could irritate eyes and throat. This prompts a recommendation for masks, especially near busy roads. The week ahead forecasts a warming trend and mostly dry conditions, though air quality remains a persistent concern due to calm winds and the absence of rain. This outlook provides residents with essential information on current and future weather patterns, alongside crucial health advisories.

Today's Detailed Weather Forecast

Today, Thursday, begins on a cooler note, which is typical for mid-January in Delhi. The day is expected to transition into a mild, sunlit afternoon. The high temperature for the day is forecast at 21.4°C. The low temperature is projected to be 9.6°C. The average temperature for the day stands at 14.8°C.


Humidity levels are anticipated to remain relatively low, at approximately 32 percent. This condition should contribute to the air feeling dry rather than clammy. Winds are expected to be gentle to moderate, with speeds peaking near 13 kilometers per hour. Visibility is predicted to be strong, reaching 10 kilometers, which is beneficial for commuters and those undertaking longer drives.

The forecast indicates 0 millimeters of rain and a 0 percent chance of precipitation. This suggests a minimal risk of any weather-related disruptions. The early morning hours are expected to be the coolest part of the day. Temperatures will then steadily increase through the late morning into mid-afternoon.

By evening, temperatures are projected to dip once more. Residents can anticipate the return of the familiar winter bite after sunset, which is scheduled for 5:46 PM. For those planning outdoor walks, the most comfortable period is likely from late morning to mid-afternoon. Early morning and late evening activities may require an additional layer of clothing.

Air Quality Concerns and Health Advisories

Yesterday’s air quality was described as:
"Severe"

That lingering haze can still irritate eyes and throat today. It is a good morning to step out, but it is best to keep a mask handy, especially near busy roads.

Delhi’s air quality on Wednesday, January 14, was alarming. The AQI (India) registered 427, placing it within the following bracket:
"Severe"

The US AQI simultaneously read 417. Both readings indicated conditions that could affect even healthy adults with extended exposure.

The primary contributors to this pollution were particulate matter. PM2.5 levels were measured at 276, and PM10 levels reached 378. Carbon monoxide (CO) was also a factor, recorded at 240, adding to the overall pollution load.

In practical terms, this type of air quality can lead to several health symptoms. These include coughing, throat irritation, headaches, and breathlessness. Such effects are particularly concerning for children, older adults, and individuals with pre-existing conditions like asthma or heart conditions.

Despite today’s sunny weather and light winds, the absence of rain means there is no such thing as a:
"washout"

This effect would quickly clear pollutants from the atmosphere. Midday sunshine might slightly improve air mixing. However, if winds remain mild, pockets of poor air quality may persist. This is especially true in traffic-heavy corridors and areas experiencing construction dust.

Today’s conditions can be summarized as:
"good weather, bad air."

Sunglasses will be helpful during the bright afternoon hours. Light layering is recommended for clothing. This includes a warm top for the morning, something lighter for lunchtime, and a jacket again after sunset.

For individuals who need to commute during peak traffic hours, considering an N95/FFP2-style mask is advised. It is also recommended to avoid long outdoor workouts. For those whose activities require them to be outside, shorter breaks with indoor recovery time can help reduce exposure to pollutants. Keeping windows closed during heavy-traffic hours may also assist in maintaining better air quality at home and in cars.

The Week Ahead

The upcoming week indicates a steadily warming trend. Continued dry conditions are also expected. January 16 is forecast to be partly cloudy, with temperatures of 23.2°C high and 11.1°C low. January 17 will be overcast but still mild, with a high of 23.7°C and a low of 13.1°C. This day may feel a touch duller and could potentially trap pollution closer to the surface.

From January 18 onward, strong sunshine is expected to return. Temperatures are projected to climb progressively. January 18 will see a high of 24.6°C. January 19 is forecast for 25.3°C. January 20 is expected to reach 25.9°C. By January 21, temperatures are predicted to hit 26.6°C. Nights will also become less chilly, with lows rising to 15.5°C by the 21st.

For outdoor plans during the week, January 16 and January 18 appear particularly pleasant weather-wise. The primary caution throughout the entire week remains air quality. Without rain and with fairly calm winds, any significant relief from pollution will depend on local dispersion and emission controls.

A bonus skywatch note indicates that the New Moon will arrive on January 18. This event typically makes for darker skies at night. However, Delhi’s existing haze and city lights can still limit stargazing opportunities.
