Mumbai's Weather: Sunshine and Warmth Amid Air Quality Challenges
On Friday, January 23, 2026, Mumbai is experiencing a day characterized by sunny and warm conditions, which are typical for late January. However, these pleasant weather patterns are accompanied by persistent concerns regarding air quality. While temperatures remain comfortable for residents and visitors alike, the air quality continues to be affected by Thursday's "poor" pollution levels, which registered an AQI-IN of 253.
Today's Detailed Weather Forecast
The weather forecast for today indicates straightforward and predictable conditions. Sunny skies are expected to dominate throughout the entire day, providing ample sunshine. The high temperature is projected to reach a warm 25.4°C, while the low temperature is set at 22.1°C. This results in an average temperature of approximately 23.5°C, making it a comfortably warm day.
Humidity levels are anticipated to be fairly noticeable, hovering around 70 percent. This level of humidity can contribute to a mild sticky feel, even when temperatures are not at their highest. Winds are forecast to pick up sufficiently to be felt, potentially reaching speeds of up to 23.8 km/h. Visibility is strong, recorded at 10 km, indicating a clear day for driving and various outdoor activities.
Rain is not expected today, with 0 mm precipitation forecast and a 0 percent chance of rain. The day is expected to trend with a softer start following sunrise at 7:15 AM. A warmer and brighter late morning will transition into the early afternoon, with the sun feeling strongest during this period. A slightly more comfortable feel is anticipated as the evening sets in after sunset at 6:26 PM. The breeze may be most noticeable later in the day, which can offer some comfort, though it does not always translate into cleaner air at street level.
Air Quality Concerns and Health Impacts
Air quality remains a significant concern in Mumbai, carrying over from yesterday's poor conditions. Thursday's pollution levels were firmly in the "poor" range, and the air may still feel heavy today, particularly around busy roads and during peak commute hours. Mumbai’s air quality on Thursday, 22 January 2026 registered AQI-IN 253 (category 4: Poor), with the US AQI at 196—levels that can trigger irritation for many people, not just those with asthma or allergies.
Elevated particulates were identified as the main culprits for yesterday's air quality. PM2.5 was measured at 115 and PM10 was recorded at 138. Both of these pollutants are closely linked with specific health effects, including coughing, throat irritation, watery eyes, and a general sense of fatigue outdoors. Carbon monoxide (CO) was also present at 409, serving as a reminder that certain areas, such as traffic corridors and enclosed, congested spaces, can experience worse conditions than the citywide average.
With today staying dry and sunny, there is no rain to help clear the particulates from the air. This means that air quality may not dramatically improve on its own, especially if winds do not disperse the pollution evenly. Individuals who are sensitive to air pollution may experience the worst exposure during their commutes, near construction activity, or during prolonged outdoor exercise.
Recommendations for Residents and Visitors
Planning for the day involves considering both comfort and caution due to the dual factors of weather and air quality. For the weather, light and breathable clothing is recommended, along with sunglasses for the afternoon glare. Keeping water on hand is important, as humidity can be deceptive even on a 25°C day.
Regarding air quality, a well-fitted mask is suggested if you will be on two-wheelers, anticipate being stuck in traffic, or are walking along main roads. If planning a workout, a shorter session is advisable, or choosing a route through greener, open areas is smarter. Pushing hard beside busy junctions should be avoided. Indoors, keeping windows closed during peak traffic hours can help mitigate exposure, and running an air purifier for a few hours may be beneficial if available.
The Week Ahead: Weather and Air Quality Outlook
The broader outlook for the week ahead indicates stable and dry conditions, with mostly sunny skies and steady warmth expected to continue. Here is a detailed forecast:
- Saturday, January 24: Sunny with temperatures ranging from 25.7°C to 20.6°C.
- Sunday, January 25: Continues with sunny weather and is expected to be a touch hotter, with temperatures between 26.8°C and 21.7°C.
- Monday, January 26: Looks like the warmest stretch of the week, with temperatures peaking near 27.8°C and a low of 22.7°C. A stronger midday sun is anticipated.
- Tuesday, January 27: Brings a small shift to partly cloudy skies, with temperatures at 26.4°C and 22.9°C.
- Wednesday and Thursday, January 28-29: Will see a return to sunny conditions, with highs around 26-27°C. Humidity is expected to be slightly drier during these days.
The best time for long outdoor plans is Saturday or Sunday morning, as these periods offer sunny conditions without reaching the week's warmest peak. Individuals who are sensitive to heat should exercise more caution around Monday afternoon. If pollution levels remain elevated, it is advisable to keep outdoor exertion lighter across the entire week.
