Mumbai, India is set for a bright and clear Wednesday, January 21, 2026, with sunny conditions and comfortable winter warmth expected throughout the day. Temperatures are projected to reach approximately 28.5°C and then decrease to 21.5°C overnight, with no rainfall anticipated. However, air quality remained in the “Poor” category yesterday, and these conditions may persist into the morning hours, advising early risers to choose less trafficked routes for outdoor activities. Today’s weather forecast indicates sunshine accompanied by a light coastal breeze. The city’s weather is described as remaining firmly in “classic January” territory. This includes clear skies, good visibility, and a steady, light breeze. The day’s high temperature is set at 28.5°C. The overnight low is expected to be 21.5°C, resulting in an average temperature near 24.5°C. Humidity levels are anticipated to be around 52 percent, which suggests the day will not feel excessively sticky for most of the period.Winds are forecast to reach a peak speed of about 19.4 kilometers per hour. This speed is sufficient to create a mild sea-breeze sensation, particularly in open areas and along the waterfront. There is a 0 percent chance of rain, and no precipitation is forecast. This allows for planning commutes and outdoor chores without concern for sudden showers. Visibility is predicted to be 10 kilometers, which is generally good for driving. However, on mornings with poor air quality, haze can still be present even when the sky appears blue.Throughout the day, a consistent rhythm is expected to unfold. This includes a pleasant and slightly cooler morning period. A brighter and warmer late morning transitioning into mid-afternoon is then anticipated. More comfortable conditions are expected to return after sunset, which is scheduled for 6:25 PM. Individuals sensitive to air quality are advised to schedule workouts for the late morning. During this time, mixing and dispersion of pollutants typically improve, as opposed to very early hours when pollution can remain closer to the ground.Yesterday, Tuesday, January 20, Mumbai recorded an Air Quality Index (AQI) of 166 according to Indian standards. This measurement places it within the “Poor” category, specifically category 3. The corresponding AQI (US) was 165. Particulate pollution was a notable concern, with PM2.5 levels at 80 and PM10 levels at 97. Carbon monoxide (CO) was measured at 325.“Poor” air often translates to throat irritation, coughing, or heavier breathing for those with asthma, allergies, or other respiratory conditions—especially during longer outdoor exposure or near congestion hotspots. Even healthy adults may feel the difference during intense exercise.Today’s sunny and dry forecast contributes to improved visibility. However, it does not automatically ensure clean air. Without rainfall to wash out particulates, air quality can remain susceptible to various factors. These include traffic volume, construction dust, and local emissions. The presence of a moderate breeze could assist in dispersing some pollutants, particularly later in the day.“This is a strong day for errands and outdoor plans—just layer your decisions with air-quality awareness.”It is advisable to carry sunglasses for the bright afternoon conditions. Keeping water readily available is also recommended, as the late-day warmth can be surprising even in January. If a route involves crowded junctions, bus stops, or extended signal waits, wearing a well-fitting mask can provide a noticeable benefit. Families with children and seniors may consider limiting playtime to parks situated away from main roads. Individuals with breathing issues should contemplate avoiding peak-traffic periods. For outdoor exercise, the late morning or early evening, after the rush hour, may prove more comfortable than the early morning.Mumbai’s forecast indicates a remarkably stable weather pattern for the upcoming week. Sunny weather is expected every day, with no rainfall appearing in the outlook.

However, it is important to monitor air quality if planning to spend extended hours outdoors. With no rain in the forecast, dust and emissions can accumulate. Therefore, periods of cleaner air may vary depending on wind conditions and traffic levels.Data referenced in this article is taken from AQI.in.
