Continental and extreme: −25 °C winters, short warm summers
Harbin has a continental monsoon climate with a huge annual temperature range. Winter runs from November to March, with January averages around −18 to −20 °C and cold snaps that fall well below −30 °C; the Songhua River freezes solid enough to walk on. Central heating (供暖) runs in homes, dormitories and classrooms from about 20 October to 20 April, so the indoor-outdoor contrast is the defining feature of daily life. Summer (June–August) is short, warm and humid, around 23 °C, and genuinely pleasant. Spring is brief, windy and dusty; autumn is short, dry and beautiful.
