Minimum temperature is recorded early in the morning close to 4 am or 5am. As a result you get to find cold mornings.

Annual Bangalore Climate Data

Bangalore experiences a tropical savanna climate (Köppen climate classification Aw) with distinct wet and dry seasons. Due to its high elevation, Bangalore usually enjoys a more moderate climate throughout the year, although occasional heat waves can make things very uncomfortable in the summer.[37] The coolest month is January with an average low temperature of 15.1 °C and the hottest month is April with an average high temperature of 33.6 °C.[38] The highest temperature ever recorded in Bangalore is 38.9 °C(recorded in March 1931) and the lowest ever is 7.8 °C (recorded in January 1884).[39][40] Winter temperatures rarely drop below 12 °C (54 °F), and summer temperatures seldom exceed 34–35 °C (<100 °F). Bangalore receives rainfall from both the northeast and the southwest monsoons and the wettest months are September, October and August, in that order.[38] The summer heat is moderated by fairly frequent thunderstorms, which occasionally cause power outages and local flooding. The heaviest rainfall recorded in a 24-hour period is 179 millimetres (7.0 in) recorded on 1 October 1997.[41]
