Mumbai is set for a sunny Monday, January 26, 2026, with warm yet manageable temperatures, making it suitable for outdoor activities, particularly in the morning. However, residents are advised that Sunday’s “Very Poor” air quality may persist, necessitating caution in traffic-heavy areas. The week ahead promises largely stable and dry conditions, with a notable shift to slightly cooler nights midweek and Thursday, January 29, emerging as an optimal day for outdoor plans due to comfortable weather.
Monday’s Forecast
Monday, January 26, 2026, begins with a bright outlook across Mumbai. A sunny day is anticipated, with no significant indications of rain. Temperatures are expected to remain warm, yet they will be manageable for residents. This creates favorable conditions for spending time outdoors, especially during the earlier parts of the day.It is important to note that yesterday’s air quality was in the “Very Poor” range. This condition can still linger into today despite the sunshine. If stepping out for a walk or commute, the morning offers pleasant conditions. However, in traffic-heavy stretches, wearing a mask is a practical consideration.Today’s forecast keeps conditions straightforward. Sunny skies are predicted throughout the day. The high temperature is expected to reach 27.7°C, while the low will be 22.6°C. The average temperature for the day is projected to be around 24.6°C.Humidity levels are anticipated to be around 58%. While this level will not create the sticky sensation associated with peak monsoon months, the afternoon sun can still feel sharp. This is particularly true on open roads and along coastal promenades.Winds are forecast to reach a peak speed of approximately 19.4 kmph. This speed is sufficient to generate a light breeze across the city. However, it is not strong enough to “flush out” the city’s air pollution on its own.The likelihood of rain remains low, with 0 mm of precipitation expected. There is a 0% chance of rain for the day. Visibility is forecast to be clear at 10 km, which is beneficial for drivers and individuals with outdoor plans.Hourly temperature fluctuations are not expected to be dramatic in this outlook. Mumbai’s typical January rhythm will still apply to the day. The morning hours are anticipated to feel the most comfortable.The midday to late afternoon period will be the brightest and warmest part of the day. The evening is expected to transition into a softer warmth, rather than a significant chill. Sunset is scheduled for 6:28 PM. Temperatures will gradually drop after sunset, and the breeze will become more noticeable once the sun has dipped below the horizon.
Air Quality Concerns and Recommendations
On Sunday, January 25, Mumbai recorded an Air Quality Index (AQI) for India of 216. This reading placed the city in Category 4, which is designated as “Very Poor.” The corresponding US AQI reading was 181. This level also signals unhealthy air conditions for many individuals.The primary concern regarding air quality was the concentration of PM2.5 particles. These were measured at 98 µg/m³. PM10 particles were recorded at 115 µg/m³. Both of these levels are elevated.Such elevated particle levels are known to irritate the throat and eyes. They can also worsen allergies for sensitive individuals. Furthermore, these conditions can trigger breathing difficulties for those with asthma or other respiratory conditions. Carbon monoxide (CO) was logged at 298, as provided in the data.Despite the presence of sunshine today, air quality does not automatically improve. Clear, dry days can sometimes allow pollutants to remain suspended in the atmosphere. This is especially true for fine particles.These conditions are particularly prevalent during calmer morning and late-night periods. The decent wind expected today may offer some minor assistance. However, without rain to “wash” the air, sensitive groups are advised to approach outdoor exposure with caution.For individuals planning to head outdoors, sunglasses and sunscreen are recommended. These items will be particularly useful during the afternoon hours. It is advisable to schedule longer outdoor workouts for either early morning or post-sunset. During these times, the heat is generally gentler.Given yesterday’s “Very Poor” AQI, considering a well-fitting mask is a practical step. This is especially relevant if one will be near construction zones, major junctions, or caught in slow-moving traffic. Keeping windows closed during periods of peak congestion can also be beneficial.Using indoor air filtration, if available, is another measure to consider. This is particularly important for children and older adults, who may be more susceptible to air quality impacts.
The Week Ahead
Mumbai’s forecast for the upcoming week indicates largely stable and dry conditions. Tuesday, January 27, is expected to remain sunny. Temperatures will range from 25.8°C to 22.5°C. Humidity levels will be slightly higher, around 68%.Wednesday, January 28, will also see sunny skies. The night is forecast to be slightly cooler, with temperatures dropping to 20.5°C. The week’s stronger winds, near 23 kmph, are expected on Wednesday. These winds may contribute to a fresher feeling after dark.Thursday, January 29, is predicted to turn warmer again. Temperatures could reach a high of 27.9°C. Humidity levels will drop significantly to 43%. This combination of conditions makes Thursday one of the more comfortable days for extended outdoor plans.Friday, January 30, stands out as the only day forecast to be partly cloudy. Despite the cloud cover, the day is still expected to remain dry. The weekend is anticipated to stay bright and clear.Saturday, January 31, will be sunny with a high of 27.4°C. Sunday, February 1, is also forecast to be sunny. It will be a touch hotter, with temperatures reaching 28.3°C.For those planning outdoor activities, Thursday, January 29, appears to be the “sweet spot.” This day offers warm, dry, and less humid conditions. Individuals sensitive to air pollution should monitor morning conditions midweek. Calmer atmospheric conditions during these times can sometimes trap particles closer to ground level. This can occur even when the sky appears perfectly clear.The data referenced in this article is taken from AQI.in.
