  Ahmedabad has a hot semi-arid climate (Köppen climate classification: BSh), with marginally less rain than required for a tropical savanna climate. There are three main seasons: summer, monsoon, and winter. Aside from the monsoon season, the climate is extremely dry. The weather is hot from March to June; the average summer maximum is 43 °C (109 °F), and the average minimum is 24 °C (75 °F). From November to February, the average maximum temperature is 30 °C (86 °F), and the average minimum is 13 °C (55 °F). Cold winds from the north are responsible for a mild chill in January. The southwest monsoon brings a humid climate from mid-June to mid-September. The average annual rainfall is about 800 millimetres (31 in), but infrequent heavy torrential rains cause local rivers to flood and it is not uncommon for droughts to occur when the monsoon does not extend as far west as usual. The highest temperature in the city was recorded on 20 May 2016, with it reaching 48 °C (118 °F).
  
  Following a heat wave in May 2010, which reached 46.8 °C (116.2 °F) and claimed hundreds of lives, the Ahmedabad Municipal Corporation (AMC), in partnership with an international coalition of health and academic groups and with support from the Climate & Development Knowledge Network, developed the Ahmedabad Heat Action Plan. Aimed at increasing awareness, sharing information and coordinating responses to reduce the health effects of heat on vulnerable populations, the action plan is the first comprehensive plan in Asia to address the threat of adverse heat on health. It also focuses on community participation, building public awareness of the risks of extreme heat, training medical and community workers to respond to and help prevent heat-related illnesses, and coordinating an interagency emergency response effort when heat waves hit.
  
  Ahmedabad has been ranked 7th best “National Clean Air City” (under Category 1 >10L Population cities) in India according to 'Swachh Vayu Survekshan 2024 Results'
