Air Quality in Bengaluru Shows Noticeable Improvement
Continuous rainfall since late September has significantly improved Bengaluru’s air quality, providing residents with much-needed respite from pollution. The Air Quality Index (AQI) readings have remained within ‘Good to Moderate’ levels, indicating that the city’s air is relatively cleaner and healthier.
The cleanest day recorded in recent weeks was September 28, 2025, when the AQI dropped to 54, marking one of the lowest readings in months. Experts attribute this to the consistent rain showers, which help wash away dust and particulate matter from the atmosphere.
However, meteorologists advise that humidity levels may cause particulate matter to linger, particularly during mornings and evenings. Residents with respiratory conditions or allergies are encouraged to use air purifiers indoors and wear masks while commuting during peak humidity hours.
Temperature Trends and Comfort Index
Bengaluru’s climate remains a pleasant contrast to many parts of India currently experiencing heat spikes. The combination of mild rainfall, overcast skies, and steady breezes has kept daytime heat at bay.
Date Temperature (°C) Weather Condition Humidity
Oct 4 19.1 – 27.9 Patchy rain, mild breeze 72%
Oct 5 19.3 – 28.0 Moderate rain 75%
Oct 6 19.4 – 27.4 Scattered showers 68%
Oct 7 20.0 – 27.6 Patchy rain, less humidity 65%
Oct 8–9 20.0 – 26.7 Partly cloudy, dry 60%
This period marks one of Bengaluru’s most comfortable weather phases, often referred to locally as the post-monsoon cool window, ideal for outdoor markets, local travel, and evening leisure activities.
Commuter Advisory: What Bengaluru Residents Should Know
With rainfall persisting across several zones, the Bengaluru Traffic Police (BTP) has urged commuters to plan their routes carefully. Certain areas like Majestic, Yeshwanthpur, Whitefield, and Electronic City are prone to minor waterlogging.
Authorities have advised motorists to:
Avoid speeding on wet roads.
Park vehicles away from trees during thunderstorms.
Check real-time traffic updates on Google Maps or the BTP Twitter handle.
Keep mobile flashlights and rain gear handy.
Public transport remains functional, with BMTC buses and Namma Metro services operating on schedule, although brief delays can occur during heavy downpours.
Farmers and Rural Forecast
In rural belts surrounding Ramanagara, Chikkaballapur, and Tumakuru, moderate rainfall is expected to benefit ragi, paddy, and vegetable cultivation. The Karnataka Agriculture Department has issued a note recommending farmers to continue field drainage practices to prevent water stagnation.
According to a KSNDMC agrometeorologist, “The rains are timely and beneficial for late Kharif crops, but farmers should monitor soil moisture closely and apply nitrogen fertilizer only after rainfall gaps.”
Health and Lifestyle Tips During Bengaluru’s Rainy Season
Despite the moderate weather, fluctuating humidity and temperature can trigger seasonal health issues. Doctors recommend the following preventive measures:
Carry light rain gear and avoid getting drenched to prevent colds and flu.
Ensure indoor ventilation to avoid mold growth due to dampness.
Drink boiled or filtered water to prevent waterborne infections.
Consume warm foods like soups and herbal teas to maintain body balance.
Fitness enthusiasts can take advantage of the cool mornings for outdoor walks or yoga sessions, though it’s best to avoid park areas during thunderstorms.
Travel and Leisure Outlook
Tourists visiting Bengaluru during this period can enjoy less crowded landmarks and lush greenery enhanced by recent rains. Must-visit attractions like Lalbagh Botanical Garden, Cubbon Park, and Nandi Hills appear particularly vibrant.
However, visitors are advised to:
Check daily weather bulletins before planning trips.
Carry waterproof shoes and jackets.
Opt for indoor attractions like Visvesvaraya Industrial Museum or Bangalore Palace during heavy rain spells.

What Lies Ahead for Bengaluru?
Weather experts predict that the second week of October 2025 will witness reduced rainfall activity and more stable conditions across Karnataka. The northeast monsoon influence will gradually pick up later in the month, potentially bringing another round of light showers.
This transition phase offers pleasant evenings, ideal for outdoor markets, food festivals, and cultural events that often mark Bengaluru’s festive calendar in October.
Conclusion
Bengaluru’s current weather paints a soothing picture for residents — cloudy yet calm, rainy yet refreshing. With moderate temperatures, improving air quality, and manageable rainfall, the city is striking a perfect climatic balance as it moves deeper into October.
While the monsoon winds down, residents can look forward to cooler mornings and breezy nights, a hallmark of Bengaluru’s much-loved climate.
