New Delhi weather: Sunny Skies, cooler mornings; AQI remains poor

New Delhi is set for a bright, winter-sunny day on Wednesday, January 14, 2026, with comfortable afternoons and a noticeably cooler start and finish. Temperatures are expected to reach about 20.2°C after a morning low near 8.5°C, and no rain is anticipated. However, the primary concern remains air quality, as yesterday's pollution was in the "Severe" range, a condition that can persist even on clear days. Residents are advised to carry a mask and keep outdoor workouts light if stepping out, particularly given the recorded PM2.5 and PM10 levels. The outlook for the coming week indicates a steady warming trend and mostly clear skies, though air quality may continue to be a factor if winds remain light.

Today's forecast indicates largely straightforward weather conditions for the capital. Sunny skies are expected throughout the day, with a 0% chance of rain. Visibility is projected to be good, maintaining around 10 kilometers.
The daytime peak temperature of 20.2°C should feel pleasant when exposed to the sun. Conversely, the minimum temperature of 8.5°C will ensure that early hours and late evenings feel distinctly wintry. Humidity levels are anticipated to average around 32%.
This humidity level typically signifies drier air, which can be beneficial for general comfort. However, drier air can also contribute to a scratchy throat sensation, particularly when pollution levels are elevated.
Winds are expected to be gentle to moderate across the region. The top speed for these winds is projected to be near 11.9 kilometers per hour. This wind speed is not considered strong enough to provide a significant "clean-air" effect.
Hour by hour, the morning is expected to be cool and crisp. This period is suggested as the best time for errands if one wishes to avoid the harsher glare of the afternoon sun. Midday through late afternoon will be mild, with the sun providing most of the warming.
A quick dip in temperature is anticipated after sunset, which is scheduled for 5:45 PM. If heading out after dark, a light jacket will likely be required again.

Air Quality Concerns

On Tuesday, January 13, New Delhi recorded an Air Quality Index (AQI) of 458 according to India's measurement system. This figure places the air quality in Category 6, which is classified as "Severe." The US AQI equivalent for the same day was also extreme, registering at 485.
A significant aspect of the pollution was the particle concentration. PM2.5 levels were recorded at 303, and PM10 levels reached 404. These levels of particle pollution are capable of triggering immediate discomfort for many individuals.
"trigger immediate discomfort for many people—burning eyes, coughing, sinus irritation, and breathlessness—especially for children, older adults, pregnant women, and anyone with asthma or heart/lung conditions."
Despite today’s sunny weather, the air quality may not improve rapidly. Calm winter conditions, coupled with cooler nights and relatively light winds, can allow pollution to persist near the surface. This phenomenon is particularly noticeable during morning and late-evening hours when atmospheric mixing is weaker.
"the sky may look blue, but the air may still feel heavy in traffic corridors and dense neighbourhood pockets."

Recommendations for Residents

To plan Wednesday effectively, shifting outdoor activities to late morning or early afternoon is recommended. During these hours, the day is warmer, and the atmosphere typically mixes more effectively. For walks or short runs, choosing green stretches away from main roads is advisable, rather than high-traffic junctions.
"A well-fitted N95/FFP2 mask is a practical add-on today, especially for commuting, two-wheeler rides, or time spent near construction or idling vehicles."
Weather-wise, the sun will be strong enough by afternoon to warrant the use of sunglasses. The morning chill suggests wearing layers that can be removed as the day warms. Maintaining good hydration is also important.
"dry air plus particulate pollution can be deceptively irritating even when you don’t feel 'hot.'"

Outlook for the Coming Week

The outlook for the upcoming week indicates a period dominated by dry and mostly sunny weather. A steady warming trend is also anticipated. Following today, high temperatures are projected to rise to 21.7°C on January 15, and 23.4°C on January 16. By January 17 to 20, highs are expected to reach between 24°C and 26°C.
Nighttime temperatures are also forecast to warm gradually. Minimums are expected to move from 10.2°C on January 15 to approximately 15.1°C by January 20. A minor change in the forecast indicates that Saturday, January 17, is expected to be overcast, with surrounding days returning to sunny conditions.
For outdoor plans, Friday, January 16, appears particularly pleasant. The day is expected to be warm but not excessively hot, with a low risk of rain. However, a cautionary note remains regarding air quality.
"if winds stay light, air quality can remain a constraint even when the weather looks inviting."
