Weather is one of the biggest concerns for a traveler to visit a country for the first time. As the big size of China, it is even more important as there can be extremes in climate from North to South especially in the winter. The daytime temperatures in Harbin in the winter would be around -30C (-22F) and night time temperatures be even lower. While the temperature in Shanghai would be over 35C ( (95F) for most of summer. So before you travel to China, it is strongly recommended that you check the conditions first. China is vast, and the climate and conditions vary widely from region to region.
Beijing in March will be like Washington DC at the same period-sometimes quite chilly, often windy, occasionally du sty--then warmer by late April, and in the 90's by May;
Traveling in mid-China will hit cool to warm weather (and very cold if climbing a mountain);
Shanghai and Hong Kong in May/June will be in the high 90's, with humidity to match. North-Central China (Beijing, Xian) is similar in climate to Nebraska and Kansas, with less snow and rain during the winter. Late winter and early spring bring regular dust storms and haze.
Before decide when to take a tour in china, it is worth checking carefully the weather conditions of each city on the itinerary.
