Shanghai has a humid subtropical climate,and experiences four distinct seasons.
Shanghai weather is generally mild and moist, with four distinct seasons – a pleasant warm spring, a hot rainy summer, a comfortable cool autumn and an overcast cold winter.
Shanghai starts the year shivering in midwinter, when temperatures can drop below freezing and the vistas are gray and misty. spring brings warmth; april to mid-may is probably one of the best times to visit there, along with autumn (late september to mid-november). in summer the hot and humid weather makes conditions outside uncomfortable, with temperatures sometimes as high as 40°c (104°f) in july and august. in short, silk long johns and down jackets are needed in winter, an ice block for each armpit in summer and an umbrella wouldn’t go astray in either of these seasons.
With a pleasant northern subtropical maritime monsoon climate, shanghai enjoys four distinct seasons, generous sunshine and abundant rainfall. its spring and autumn are relatively short compared with summer and winter. the average annual temperature is 16 degrees celsius. the city has a frost-free period lasting up to 230 days a year, and receives an average annual rainfall of 1,200 millimeters.
