Changsha Climate - Seasons & Travel Advice
The scorching summer and cold winter are two distinctive seasons in Changsha. The summer comes around the later May with high heat and heavy humidity. The sweltering climate of July and August is particularly stifling.
Changsha's winter comes around November bringing little sunlight and heavy fogs. Although it is reported that the average temperature in winter is about five degrees, the winter weather in Changsha can be severely cold as those in the northern China cities due to the great humidity carried by the river winds from Xiangjiang River. Like Wuhan, the city has no heaters and we suggest travelers bring cotton and packed clothes, gloves and scarves and a hat for the windy days. Most of the rest days in a year are misty and cloudy.
Spring, during the months from March through May, is the best time to travel to the city. Likewise, September is a good time to visit, during the short but pleasant autumn period when the red maples on Long Island (Juzizhou) are in full blossom and the temperatures in this period are around 15C (59F) to 20C (68F).
One thing a traveler should bear in mind is that Changsha weather changes greatly during the transit period between spring and summer or summer and autumn. An unexpected summer rainstorm could arrive suddenly on a sunny day, so make sure to bring an umbrella with you. The long rain period starts in October and continues for one or two months, therefore one should plan indoor tourist activities during the latter part of a year.
