Delhi weather forecast: Sunny skies, comfortable temperatures; air quality alert

New Delhi is set for a bright, winter-sunny day on Saturday, January 24, 2026, with comfortable afternoon temperatures and a distinctly cool start. The forecast indicates largely dry conditions, making it suitable for outdoor activities. However, yesterday’s air quality was in the Severe bracket, and lingering pollution can still make the air feel harsh even when the sky appears clear. Therefore, keeping a mask handy is sensible, especially near busy roads.

Today’s weather forecast predicts clear skies, a cool morning, and a mild afternoon. Saturday is expected to reach a high of approximately 18.9°C. The low temperature is forecast to be about 9.6°C. This results in an average temperature near 13.6°C, which is characteristic of late-January weather in Delhi. Skies are anticipated to remain sunny throughout the day. Rainfall is considered essentially negligible, with approximately 0.01 mm expected and a 0% chance of rain. This allows for planning errands or outdoor time without concerns about showers.


Humidity levels are expected to average around 60%. This can contribute to mornings feeling a bit crisper. Afternoons, however, should feel more comfortable under the sun. Winds are projected to be light to moderate. A peak wind speed near 15.8 km/h is anticipated. This level of wind is sufficient for a mild breeze. However, it is not the kind of wind that meaningfully disperses pollution.

Through the day, a familiar pattern is expected. This includes a chilly early morning period. A pleasant warm-up is anticipated by late morning. The best window for outdoor activities is in the early-to-mid afternoon. During this time, temperatures are most comfortable. By evening, the mercury will fall again. A light jacket will quickly become necessary after sunset, which is at 5:53 PM. Sunrise is at 7:13 AM. The first hour or two after dawn may still feel cold in the shade.

Air Quality Concerns

Friday, January 23, saw Delhi’s Air Quality Index (AQI) at 350. This placed it firmly in the Severe (Category 5) range according to India’s standards. The U.S. AQI equivalent was also extremely high, registering at 265. This level signals air that can be unhealthy for everyone, not just sensitive groups.

Particulate matter remained a significant concern following Friday's conditions. Levels of PM2.5 were recorded at 185. PM10 levels reached 247. These fine particles are strongly linked to various health issues. Such issues include throat and eye irritation, coughing, and headaches. They can also cause flare-ups of asthma or allergies. These effects are particularly noticeable during commutes and near construction or traffic corridors. With today’s weather being sunny and largely calm, the air may appear cleaner than it actually feels. Without strong winds or rain, pollution often disperses slowly. In summary, the sunshine is welcome, but it does not automatically mean breathable air.

Health and Safety Recommendations

If heading out, layering up is advisable. A warm top is recommended for the morning chill. Something lighter should be worn underneath for the midday sun. Sunglasses will be helpful in the bright afternoon. Given yesterday’s Severe AQI, a well-fitting mask remains a smart idea for outdoor exercise, long rides, or time spent at intersections.

Outdoor workouts should ideally be scheduled for late morning to early afternoon. This is when the cold bite eases. Individuals with respiratory issues should keep exertion light. Preferring parks over roadside stretches is also recommended for these individuals. Indoors, running an air purifier, if available, can help. Keeping windows shut during peak traffic hours can also reduce exposure to pollutants.

Extended Forecast

The next few days are expected to remain mostly pleasant and sunny. Sunday, January 25, will stay sunny with a high near 19.3°C and a low around 9.3°C. Monday, January 26, looks warmer, with temperatures rising to about 21.9°C. It will also be sunny with calmer winds.

Midweek brings a noticeable shift in weather patterns. Tuesday, January 27, turns more unsettled. The forecast mentions:
"patchy rain nearby"
A warmer high near 24.3°C is expected, along with a strong 87% chance of rain. This period can often temporarily help wash down particulates. Wednesday, January 28, looks wetter with moderate rain. Approximately 5.79 mm of rainfall is expected. Highs will be closer to 20.2°C. After Wednesday, Thursday, January 29, turns overcast but is largely dry. Friday, January 30, trends sunny again, with temperatures around 22.3°C.

Planning Your Week

The best day for outdoor plans is Monday, January 26. This day is forecast to be sunny, warm, and have a low rain risk. Days to be cautious are January 27–28. Rain during this period could disrupt travel, even if it offers some air-quality relief. The light to moderate winds are not the kind that meaningfully:
"blows out"
pollution.
