Kolkata's Bright Tuesday Brings Sunshine But Pollution Lingers
Kolkata woke up to a beautiful Tuesday morning on January 13, 2026. The city is experiencing clear blue skies and abundant sunshine throughout the day. Morning temperatures started cool but will climb to comfortably warm levels by afternoon.
However, this pleasant weather picture hides a concerning reality. The city's air quality remains problematic despite the sunny conditions.
Today's Weather Conditions
Kolkata residents can expect uninterrupted sunshine today. The morning began with mild winter chill, but temperatures will rise steadily. Forecasters predict a high of 26.1°C and a low of 12.8°C for the day.
The average temperature should settle around 19.1°C. Humidity levels stay relatively low at approximately 33 percent. This dry air makes the afternoon warmth feel comfortable rather than sticky.
Winds will provide light relief throughout the day. Speeds may reach up to 14.8 kilometers per hour at times. These breezes create pleasant conditions in open areas across the city.
Rain is completely absent from today's forecast. Precipitation stands at zero millimeters with zero percent chance. Visibility measures strong at about 10 kilometers officially.
Temperature changes follow predictable patterns today. Early morning offers the coolest and most comfortable period. Midday through late afternoon brings brighter and warmer conditions.
Sunset occurs at 5:12 PM. Temperatures will drop quickly after this time. For outdoor exercise, morning hours provide the safest window for comfort and reduced glare.
Air Quality Remains a Serious Concern
Monday's air quality readings paint a troubling picture. Kolkata's air on January 12 fell firmly into the "poor" category. The Indian AQI scale registered 297, placing it in Category 4.
On the US AQI scale, the reading reached 228. Both measurements indicate unhealthy conditions for residents. High particulate levels drove this pollution spike.
PM2.5 levels recorded 147 while PM10 reached 185. These fine particles typically irritate throats and eyes. They can worsen asthma, allergies, and other respiratory problems.
Children, seniors, and long-hour commuters face particular risks. Today's sunny, dry weather doesn't guarantee cleaner air. Without rain to wash away particles and only modest winds, pollution lingers near the surface.
The slight daytime breeze might offer minimal assistance. However, if emissions continue at current levels, air quality remains harsh. This effect intensifies near major roads and active construction zones.
Health Recommendations for Residents
Today presents classic Kolkata winter conditions. Residents should prepare with sunglasses and light layers. The day transitions from comfortable morning to warm afternoon to cooler evening.
Two-wheeler riders and those spending time at traffic crossings need special precautions. High-quality masks like N95 or KN95 can reduce exposure to fine particles.
Schedule outdoor activities carefully. The period after sunrise but before late morning works best. Morning chill eases during this window before full daytime heating begins.
People with breathing sensitivities should keep medications handy. Consider indoor workouts if irritation develops. Even on sunny days, choose quieter streets or parks away from heavy traffic for walks.
Weekly Weather Outlook
The coming week promises consistent sunshine across Kolkata. No rainfall is expected through January 19. High temperatures will hold around 26–27°C through Saturday, January 17.
Nighttime lows mostly stay between 12–13°C. These pleasantly cool conditions are especially noticeable during early morning hours.
A warming trend begins Sunday. January 18 forecasts show highs reaching 28.5°C with lows at 15.5°C. January 19 climbs further to approximately 30.2°C highs and 16.2°C lows.
This temperature jump could make afternoons feel almost summer-like. For comfortable outdoor activities, Tuesday through Friday (January 13-16) appear ideal. Sunday and Monday may require extra hydration and sun protection during peak hours.
Pollution Context and Recent Trends
Kolkata has struggled with persistently high pollution levels recently. Several days last week touched the "severe" category. AQI-IN readings ranged from 300+ to 400 during that period.
Yesterday's "poor" reading at 297 represents a slight improvement. However, it still indicates unhealthy air quality. This offers minor relief rather than signaling truly clean air days.
Residents must remain vigilant about air quality despite pleasant weather conditions. The combination of sunshine and pollution creates deceptive conditions that require careful attention to health precautions.
