The four seasons in Wuhan are clearly marked, with extreme temperatures dominating both summer and winter here.
The summer here is almost unbearable. Wuhan is one of China's "Three Furnaces" (the other two being Nanjing and Chongqing), with an intensely hot and dry heat and temperatures averaging about 32 degrees Centigrade in June, July and August.
The heat also fells like it will last for eternity, with spells lasting for weeks on end and little difference in temperature between day and night. Although rainfall is fairly high at this time, it provides little respite from the city heat.
The winter here is also pretty unpleasant with minimum temperatures in January and February of 1 or 2 degrees Centigrade.
The best time to visit this "furnace" is autumn, when temperatures are much more manageable and there is less rainfall than at other times of the year.
