Delhi Weather Today: Clear Skies, Perfect Sunshine, But Toxic Air Still a Threat
The weather in New Delhi on December 5, 2025, offers nearly perfect conditions—bright sunshine, crisp air, and a comfortable temperature spread ideal for weekend planning. Yet, despite the beautiful skies, a major concern continues to overshadow the day: the city’s persistently dangerous air quality.
Data sourced from AQI.in shows that while temperatures remain pleasant, air pollution still poses significant health risks. Yesterday’s Air Quality Index (AQI) stood at a severe 315, only slightly lower than the even more alarming 351 recorded on December 4.
Below is a complete breakdown of today’s weather, a detailed AQI analysis, health recommendations, and a week-long forecast to help you plan ahead.
Today’s Weather: A Bright, Clear Day Across the Capital
New Delhi begins the day at a cool 13.5°C, creating the perfect morning for a walk, run, or cycling session. Clear skies and refreshing air movement give the morning a clean, invigorating feel—at least in terms of temperature.
As the day unfolds, the weather continues to be pleasant, with the daytime high expected to reach 23.4°C. Light winds of around 8.6 km/h are expected, helping maintain a balanced temperature throughout the afternoon. These winds may not be strong enough to drastically improve pollution levels, but they do add comfort to outdoor activities.
Weather highlights:
- Morning temperature: 13.5°C
- Daytime high: 23.4°C
- Wind speed: Up to 8.6 km/h
- Humidity: Low at just 19%
- Visibility: Excellent at 10 km
- Rain: None expected
The evening will see a gradual dip in temperatures, enough to warrant a light jacket for those staying out after sundown. Overall, the weather is perfect for outdoor plans—if not for the pollution concerns.
Yesterday’s AQI: Severe Pollution Despite Slight Improvement
While the skies today may look clear, yesterday’s AQI of 315 paints a very different picture of the city’s air. Classified as “severe,” this level can cause respiratory discomfort, eye irritation, and heightened risk for people with asthma or other lung conditions.
Key pollutant levels recorded yesterday:
- PM2.5: 157 µg/m³
- PM10: 205 µg/m³
- CO: 556 µg/m³
These levels are high enough to cause breathing difficulty even among healthy individuals, and far worse for children, elderly people, and those with chronic illnesses.
Despite the severity, yesterday did show a small improvement from the previous day’s AQI of 351, the week’s highest. This downward trend might continue if weather conditions remain stable, but for now, pollution remains a serious threat.
Health Advisory: Enjoy the Sunshine, But Take Precautions
Today’s weather may tempt many to spend more time outdoors, but certain precautions remain essential, especially given the lingering pollution levels from yesterday.
Recommendations for all residents:
- Wear a mask while commuting or walking near high-traffic areas.
- Use sunglasses and sunscreen during midday hours to avoid strong UV exposure.
- Stay hydrated, as dry air can irritate your throat and nasal passages.
- Limit outdoor activity during early morning and late evening, when pollution tends to spike.
For sensitive groups:
- People with asthma, bronchitis, heart conditions, or allergies should:
- Avoid outdoor exercise.
- Keep windows closed during peak hours.
- Use air purifiers indoors if possible.
- Carry prescribed inhalers or medications.
A morning walk is still a good idea if pollution levels improve later, but carrying a mask throughout the day is highly recommended.
Week Ahead: Steady Sunshine and Slightly Warmer Days
New Delhi’s upcoming week promises more stable and pleasant weather. Temperatures are expected to rise gradually, but the atmosphere will remain comfortable, making it a good time for outdoor gatherings, short trips, or simply enjoying the winter sunshine.
Expected weekly temperature range:
- Daytime highs: 25.5°C to 27.2°C
- Nighttime lows: 14.5°C to 16.7°C
Clear skies are predicted throughout the week with no rain or snowfall expected. The warmest days will be December 7 and 8, with highs of 26.4°C and 27.2°C, respectively.
Evenings will maintain a cool breeze, so light layers remain necessary for nighttime outings.
Air Quality Trends: Pollution Still High But Showing Early Signs of Improvement
While Delhi’s air quality remains far from healthy, the AQI trend from earlier in the week shows cautious optimism. Yesterday’s AQI of 315 is lower than the 351 recorded on December 4, indicating a slight easing in pollution intensity.
Though not enough to breathe easy yet, this decline may signal that atmospheric conditions—especially the increase in wind movement and clearer sky—could gradually help disperse pollutants over the next few days.
However, such improvements are often temporary. Residents should monitor AQI levels closely before planning outdoor activities.
Final Outlook: Enjoy the Weather, Stay Alert to Pollution
Delhi’s weather today is undeniably inviting—sunny, crisp, and comfortable. But the city’s pollution levels remain a serious concern. With yesterday’s air quality still classified as severe, residents must balance enjoying the beautiful weather with taking essential health precautions.
Carrying masks, avoiding peak traffic timings, and staying informed about daily AQI reports will help everyone navigate the ongoing pollution challenge safely.
