Bengaluru Heavy Rain, Poor AQI 129: Weekly Forecast

Bengaluru Grapples with Heavy Rainfall and Poor Air Quality

Bengaluru residents woke up to a waterlogged city on November 30, 2025, as heavy rainfall lashed the IT capital. The downpour brings a complex mix of relief and concern, following a day of significantly poor air quality. With data sourced from AQI.in, this forecast provides a comprehensive look at the current conditions and what the week ahead holds for the city's populace.

Today's Soaking Wet Conditions

The city is experiencing a consistently wet day, with temperatures showing minimal fluctuation. The mercury is hovering between a minimum of 18.2°C and a maximum of 18.9°C. Adding to the dampness is a high humidity level of 92%, creating a misty and chilly atmosphere across Bengaluru.

Precipitation is a dominant feature, with an expected rainfall of 21.63 mm. The chance of rain is a near-certain 96%, making it imperative for everyone to carry rain gear. Winds are expected to blow at a speed of 18.4 km/h, providing a breezy counterpoint to the persistent rain. The skies will remain overcast throughout the evening, with cooler temperatures and a gentle breeze setting in after sunset.

Recap of Yesterday's Air Quality

Before the rains arrived, Bengaluru was dealing with a different environmental challenge. On November 29, the city's air quality was categorized as 'Poor', with an Air Quality Index (AQI) of 129. This deterioration was primarily driven by elevated levels of harmful pollutants.

The concentration of the fine particulate matter PM2.5 was recorded at 67 µg/m³, while the coarser PM10 reached 95 µg/m³. Furthermore, carbon monoxide levels were high at 617 µg/m³. These pollutants are largely attributed to emissions from the city's dense traffic and various industrial activities.

Health Advisories and Day Planning Tips

The current heavy rainfall presents a double-edged sword for the city's air pollution. On one hand, it helps wash away and settle some of the particulate matter, offering a temporary respite. However, the accompanying high humidity can sometimes trap pollutants close to the ground, especially in areas with poor ventilation, leading to stagnant conditions.

In light of this, health advisories are in place. Individuals with pre-existing respiratory conditions such as asthma are advised to exercise caution and limit prolonged outdoor exposure, particularly during peak traffic hours. For all residents, carrying an umbrella is non-negotiable, and having a mask handy for outdoor commutes is a wise precaution.

Here are some practical tips to navigate the day:

  • Morning Walk: You can still enjoy a brisk walk in the cool, rainy morning but be sure to steer clear of waterlogged areas to avoid accidents and water-borne diseases.
  • Commuting: Consider using public transport or carpooling to help reduce the overall emission load. Keep a mask with you for any outdoor travel.
  • Evening Plans: With rain expected to continue into the night, opting for indoor activities is the safest and most comfortable choice.
  • Health Precautions: Stay well-hydrated and ensure you have your allergy or respiratory medications accessible if you are prone to such issues.
