Mumbai residents can step out into pleasant sunshine today, Friday, December 5, 2025, but are advised to remain cautious about air quality. The city is experiencing a clear, sunny day with a maximum temperature of 30.4°C, a welcome change following yesterday's alarming air pollution levels.
Today's Weather: Ideal Conditions for Outdoor Plans
The day began with bright sunshine and clear skies, offering near-perfect weather. A gentle breeze is blowing at speeds up to 18 kph, making the warmth feel comfortable. The humidity is at a moderate 51%, preventing the day from becoming too muggy.
The evening will see temperatures cooling down to a pleasant 24.3°C, with sunset expected around 6:00 PM. This makes the late afternoon and evening ideal for outdoor activities like walks or dining. Experts recommend dressing lightly for the day and carrying a light jacket for the cooler evening breeze.
Lingering Concerns from Yesterday's 'Very Poor' Air
Despite today's clear skies, the memory of Thursday's hazardous air lingers. On December 4, Mumbai's Air Quality Index (AQI) hit 158, placing it in the 'very poor' category. The air was laden with dangerous pollutants.
The primary culprits were fine particulate matter: PM2.5 levels reached 78 µg/m³ and PM10 was at 100 µg/m³. Additionally, carbon monoxide (CO) levels were elevated at 280 µg/m³. Such pollution can cause breathing difficulties, especially for children, the elderly, and those with respiratory or heart conditions.
While today's wind might help disperse some pollutants, authorities and health experts advise continued vigilance. It is wise to avoid prolonged exposure in high-traffic zones, and sensitive individuals should consider using masks or air purifiers.
Your Daily Guide: Navigating Weather and Air Quality
Based on current conditions, here are some recommendations for Mumbaikars to plan their day effectively:
- Morning: Perfect for a refreshing outdoor walk or exercise, taking advantage of the cleaner morning air.
- Afternoon: Stay hydrated, use sunglasses, and try to avoid direct sun during peak hours around noon.
- Evening: Enjoy outdoor dining or a stroll along the coast as the cool breeze sets in.
- Precaution: If commuting through busy, congested areas, wearing a mask can help reduce exposure to lingering pollutants.
Weekly Forecast: Consistent Sunshine Ahead
The good news for planners is that the sunny weather is set to continue. The week ahead promises stable and clear conditions, ideal for all outdoor plans and weekend getaways.
December 6-7: Sunny skies will persist with temperatures steady around 30°C.
December 8-9: A slight dip in the maximum temperature to around 29.4°C is expected, while nights remain cool at about 23°C.
December 10-11: The dry and sunny pattern holds, with temperatures ranging between 29°C and 30°C.
Throughout the week, humidity levels are expected to drop slightly, enhancing comfort. Residents are reminded to stay hydrated and use sun protection during the day.
A Glimmer of Hope in Air Quality Trends
An interesting insight from the pollution data offers a slight positive note. While yesterday's AQI of 158 was 'very poor', it was actually an improvement over the previous week's averages, which frequently remained above 200.
This suggests a potential, gradual improvement in air quality, possibly aided by stable weather conditions. However, it also underscores the need for sustained public awareness and adoption of sustainable practices to combat pollution long-term.
