The three large cities along the Yangtze River – Chongqing, Wuhan and Nanjing – are known traditionally as the ‘three furnaces of China’. Between April and September, the temperature in the Yangtze River valley reach 36 ℃ (97 ℉) and above. Spring and autumn are therefore the best seasons for making the river cruises. However, with the tall mountains and gorges through which the river threads its path, precipitation is very high and the peaks are often shrouded in cloud and mist, although a light haze can enhance the beauty of the scenery. Summer rains are torrential; you may find thunderstorms dramatic if you are on board your boat but a nuisance should you be trying to sightsee ashore. The winters are short, cold and crisp. Late-summer travels will coincide with the high-water periods, when the river rises swiftly, almost perceptibly.
