What is the climate classification of Bangalore?
Bangalore (officially Bengaluru) features a tropical savanna climate with distinct dry and wet seasons under the Köppen climate classification (Aw). Due to its elevation on the Deccan Plateau, the city avoids the extreme heat typical of coastal or low-lying Indian cities like Chennai or Hyderabad. The average annual rainfall in Bangalore is approximately 970 millimeters (38.2 inches), distributed across two separate monsoon periods. Relative humidity fluctuates between 35% during dry winter afternoons and over 85% during heavy monsoon rains.
Seasonal Breakdown of Weather in Bangalore
The year in Bangalore is categorized into four primary seasons: summer, the Southwest monsoon, the Northeast monsoon, and winter. Each season brings distinct changes in daily temperatures, precipitation levels, and atmospheric humidity.
1. Summer (March to May)
Summer in Bangalore begins in March and peaks in April, which is statistically the hottest month of the year. Maximum afternoon temperatures average around 34°C to 36°C (93°F to 97°F), though extreme heatwaves can occasionally push temperatures up to 38°C (100°F). Despite the heat, evenings often cool down due to elevated atmospheric pressure relief. By late April and May, pre-monsoon convective thunderstorms—locally known as mango showers—frequently drop late-afternoon temperatures and bring temporary rainfall.
2. Southwest Monsoon (June to September)
The Southwest monsoon arrives in early June, bringing heavy cloud cover and sustained rainfall through September. Daytime temperatures drop noticeably, averaging between 27°C and 29°C (80°F to 84°F). June, July, and August experience consistent rain showers, moderate winds, and elevated humidity levels averaging 75% to 85%. While continuous torrential downpours are rarer than on the western coast, steady intermittent precipitation is common during these four months.
3. Northeast Monsoon (October to November)
The Northeast monsoon, or retreating monsoon, affects Bangalore during October and November. October is historically the wettest month of the year, recording an average monthly rainfall of approximately 180 millimeters (7.1 inches). Thunderstorms are frequent during this transitional period. Temperatures gradually fall, with daytime highs around 28°C (82°F) and nighttime lows dropping to 19°C (66°F).
4. Winter (December to February)
Winter in Bangalore lasts from December through February, providing clear skies, light winds, and comfortable temperatures. January is the coldest month, with average nighttime lows falling between 14°C and 16°C (57°F to 61°F), though record lows have touched 9°C (48°F) in past decades. Daytime highs average a pleasant 28°C (82°F). Winter precipitation is minimal, making this season the driest time of the year.

What is the best time to visit Bangalore?
The best time to visit Bangalore is between October and February, when the weather is consistently dry, cool, and comfortable for outdoor activities. During these winter months, humidity remains low and afternoon temperatures rarely exceed 29°C (84°F), creating ideal conditions for sightseeing, parks exploration, and walking. Visitors planning outdoor trips should pack light layers, as early mornings and late evenings can feel crisp.
How does urban growth affect Bangalore weather?
In recent decades, rapid urbanization has moderately influenced Bangalore local microclimate through the urban heat island (UHI) effect. The reduction of historical green spaces and lake ecosystems, combined with increased concrete surfaces, has raised average nighttime temperatures by 1°C to 2°C over the past thirty years. Additionally, localized intense precipitation events have become more frequent during the monsoon season due to changing atmospheric dynamics over urban corridors.
What should you wear in Bangalore throughout the year?
Packing appropriately for Bangalore depends on the season, though lightweight breathable fabrics are suitable year-round:
- Summer (March–May): Wear light cotton or linen clothing, sunglasses, and sunscreen. Carry a light umbrella for unexpected pre-monsoon showers in May.
- Monsoon (June–November): Bring quick-drying fabrics, waterproof outerwear, robust umbrellas, and non-slip footwear to navigate wet streets.
- Winter (December–February): Pack light jackets, sweaters, or cardigans for cool mornings and evenings when temperatures drop to 14°C–16°C.
