Chengdu experiences a humid subtropical monsoon climate characterized by four distinct seasons and a persistent layer of cloud or fog due to its location in the Sichuan Basin. Summers, typically from July to August, are hot and very humid, with temperatures often reaching 30°C (86°F) and significant rainfall. Winters, spanning from December to February, are generally cold, damp, and gray; while temperatures rarely drop far below freezing and snow is uncommon, the high humidity creates a biting chill that makes it feel colder than the thermometer suggests. Spring and autumn are the most pleasant times to visit, offering mild temperatures and more comfortable conditions for exploring the city.
