Chongqing has a monsoon-influenced humid subtropical climate (Köppen Cfa), and for most of the year experiences very humid conditions. Known as one of the "Three Furnaces" of the Yangtze River, along with Wuhan and Nanjing, its summers are long and among the hottest and most humid in China, with highs of 33 to 34 °C (91 to 93 °F) in July and August in the urban area. Winters are short and somewhat mild, but damp and overcast. The city's location in the Sichuan Basin causes it to have one of the lowest sunshine totals annually in China, at only 1055 hours.
Chongqing, with over 100 days of fog per year,is also known as the "Fog City" , and a thick layer of fog shrouds it for 68 days per year during the spring and autumn.During the Second Sino-Japanese War, this special weather possibly played a role in protecting the city from being overrun by the Imperial Japanese Army. In recent years, the strong industrial development has degraded the air quality further, and the municipal government has been aggressively trying to improve the city's air quality.The so-called "blue sky days" (days with air quality within or better than slight pollution) number have been on the rise.
Conditions are cooler in the southeast part of the municipality due to the higher elevations there
