Weather of Haerbin
Harbin is infamous for its very cold winters — it is at the same latitude as Montreal, and winter temperatures as low as -38.1°C have been recorded. Bring more clothes than you will think you will need so that you can layer. Average daytime summer temperatures are in the mid 20s(°C) with a few weeks reaching low 30s, while the coldest part of winter averages a chilly -17°C.
The winter can become dreary if you are a longterm resident, as the entire city uses coal for heat the air quality rapidly decreases during these months.
Harbin can be a great place to visit in the summer. The weather is cool and it seems to be perpetually breezy, and most of Harbin$$s streets are lined with trees. Because the city is so cold all winter, life almost explodes and people crowd the streets until late at night eating kabobs, playing poker, and drinking Hapi (Harbin Beer). This is a great escape from the heat of Beijing. A trip up to the border regions this time of year would be nice as well.
