Delhi's Republic Day Dawns Sunny But Polluted
New Delhi welcomed Republic Day on Monday, January 26, 2026, with clear skies and abundant sunshine, creating pleasant conditions for celebrations. However, the city's air quality told a different story, with lingering pollution from the previous day casting a shadow over the otherwise beautiful weather.
Detailed Monday Weather Analysis
The capital experienced a comfortable winter day with afternoon temperatures peaking near 21°C. The maximum temperature reached 21.4°C while the minimum dropped to 10.1°C, resulting in an average temperature of approximately 15.2°C throughout the day.
Key weather parameters included:
- Humidity levels remained manageable at around 46 percent
- Visibility extended up to 10 kilometers, offering clearer views than typical for late January
- Wind speeds remained gentle, topping at about 6.1 kilometers per hour
- Zero precipitation with no chance of rain, ensuring uninterrupted outdoor plans
The day followed Delhi's typical January pattern with cool mornings that warmed significantly by late morning and early afternoon. Following sunset at 5:55 PM, temperatures dropped noticeably, creating a sharp contrast to the daytime warmth.
Air Quality Concerns Persist
Despite the sunny conditions, air quality remained a significant concern. Sunday, January 25, had recorded poor to very unhealthy air with an AQI-IN of 210 (category 4). The primary pollutants included PM2.5 at 106 and PM10 at 134, along with carbon monoxide levels of 264.
This level of pollution often causes breathing discomfort for sensitive groups and can irritate even healthy individuals during prolonged exposure.
The combination of light winds and no rain on Monday meant pollutants were not effectively dispersed, potentially causing symptoms like dry throat, watery eyes, or mild headaches to persist from the previous day's exposure.
Health Recommendations for Residents
Given the air quality conditions, health experts suggested several precautions:
- The midday period offered the optimal window for outdoor activities when temperatures were comfortable and visibility good
- Wearing sunglasses proved beneficial during bright afternoon conditions
- A light jacket or hoodie remained necessary for early mornings and evenings after 6 PM
- Those commuting on two-wheelers or spending time at busy intersections were advised to consider wearing well-fitted masks
- Pollution-sensitive individuals were encouraged to keep workouts indoors or schedule outdoor exercise for late morning rather than dawn
Weekly Weather Outlook
The coming week presents a dynamic weather pattern with significant changes ahead:
January 27: Moderate rain expected with an 88% chance of precipitation and approximately 5.48 millimeters of rainfall. High temperature forecast at 21.3°C with a low of 13°C.
January 28: Another day of moderate rain anticipated with 5.26 millimeters expected and 88% chance of precipitation. Humidity levels will rise significantly to 83% with highs of 18.9°C and lows of 12.8°C.
January 29 to February 1: A return to sunny conditions with gradually increasing temperatures. Daytime highs will climb from 21.6°C to 26°C by February 1, while nighttime lows will warm up to 14.7°C.
The rainy days may temporarily improve air quality by washing out particulates, though post-rain humidity can sometimes make lingering pollution feel heavier.
For those planning outdoor activities, January 29 and 30 appear optimal—offering sunny conditions without excessive heat, typically occurring after rain has settled dust particles.
