New Delhi Braces for Rainy Tuesday Amid Lingering Severe Pollution
New Delhi is set for a damp and mild winter day on Tuesday, January 27, 2026, with moderate rainfall expected throughout the day. While temperatures remain comfortable, the city continues to grapple with significant air quality concerns following yesterday's severe pollution levels.
Today's Detailed Weather Forecast
The capital's weather outlook indicates moderate rain showers with temperatures ranging from a low of 12.8°C to a high of 20.7°C. The average temperature is projected to be around 15.9°C, which is considered pleasant for late January standards.
Key weather parameters for Tuesday include:
- High probability of precipitation at 90% with total rainfall near 8.45 mm
- Rainfall expected to peak from late morning through afternoon hours
- Wind speeds topping out near 15.5 km/h with occasional gusts
- Average humidity around 61% creating muggy conditions at times
- Visibility projected at approximately 9.8 km, suggesting hazy conditions
The rainfall will diminish any potential sunshine and create wet road conditions that could impact commutes throughout the day. Evening plans may require adjustments for rain, though complete washouts are not anticipated.
Persistent Air Quality Crisis
Despite the expected rainfall, air quality remains a major concern for Delhi residents. Monday's pollution levels were categorized as severe, with the AQI (India) registering at 323 and the US AQI reading at 258.
Pollution measurements from Monday included:
- PM2.5 levels measured at 167
- PM10 levels recorded at 210
- Particulate pollution identified as the major driver of poor air quality
These pollution levels typically aggravate respiratory symptoms including cough, throat irritation, breathlessness, and asthma complications. The impact is particularly significant for vulnerable groups including children, older adults, and individuals with pre-existing heart or lung conditions.
While rainfall can provide temporary relief by knocking down airborne dust and particulates, pollution levels can rebound quickly between showers, especially in dense traffic corridors and areas with limited wind movement.
Essential Safety Recommendations for Residents
Given the dual challenges of rainfall and poor air quality, Delhi residents are advised to take specific precautions:
- Carry rain protection: Umbrellas or light rain jackets are essential for commutes
- Wear appropriate footwear: Closed shoes recommended due to likely puddles and splashes
- Use protective masks: Well-fitted masks remain crucial in traffic-heavy zones
- Adjust outdoor activities: Outdoor workouts should be replaced with indoor sessions
- Plan travel accordingly: Account for longer travel times due to wet road conditions
- Monitor exposure: Minimize prolonged outdoor exposure, especially for sensitive individuals
The late morning period often provides the most comfortable window for outdoor activities, after temperatures warm slightly but before roads become heavily congested.
Astronomical Conditions and Visibility
Astronomy enthusiasts may find brief windows between showers for observation. Sunrise is scheduled for 7:12 AM, with sunset at 5:56 PM. The moon is in a Waxing Gibbous phase with approximately 59% illumination, expected to rise at 12:12 PM and potentially visible later if clouds clear during nighttime hours.
Weekly Weather Outlook and Trends
The weather pattern shows significant improvement as the week progresses:
- Wednesday, January 28: Unsettled conditions continue with patchy rain nearby, temperatures between 12.9°C and 19.6°C, humidity near 80%
- Thursday, January 29: Clearer skies expected with sunny and drier conditions, temperatures ranging from 11.8°C to 21.4°C
- Friday, January 30: Partly cloudy skies forecast with temperatures around 13.2°C to 22.8°C
- Weekend Outlook: Warming trend continues with Saturday reaching near 24.1°C and Sunday potentially the warmest day at 25.8°C, coinciding with a Full Moon
- Monday, February 2: Slight cooling expected with partly cloudy skies and temperatures around 23.6°C
Long-Term Weather Patterns and Considerations
Following today's wet conditions and tomorrow's unsettled weather, New Delhi is transitioning into a classic late-winter pattern characterized by clearer skies, warmer afternoons, and cool nights. The period from January 29 through February 1 appears most favorable for outdoor activities.
However, residents should remain vigilant about air quality even as weather improves. The combination of clearer skies and light winds can sometimes allow pollution to build up again, particularly in urban areas with heavy traffic. Morning haze should be monitored regularly, especially for those with respiratory sensitivities.
This weather transition represents a typical seasonal shift for the region, though the persistent pollution concerns highlight the ongoing environmental challenges facing India's capital city during winter months.
