Changchun, the capital of Jilin province, sits on a plain in the heart of Northeast China (Manchuria), far inland at approximately 43.82°N, 125.32°E. It has a monsoon-influenced humid continental climate (Köppen Dwa) — with long, frigid, dry winters and warm, humid, rainy summers — shaped by the Siberian winter monsoon and the East Asian summer monsoon, giving a very large annual temperature range.
Summer, from June to August, is warm to hot and the wet season, with July the warmest month — average highs around 27–28°C and humid, showery conditions. The East Asian summer monsoon delivers almost all of the year's rain in these months, often as afternoon thunderstorms, and the greenery is a sharp contrast to the barren cold season. May and September are pleasant, drier shoulder months.
Winter, from November to March, is long, bitterly cold and dry, with January the coldest month — average highs around -8°C and lows near -16 to -18°C, and cold snaps driven by Siberian air that can plunge below -25°C. Despite the cold, winter is often sunny, as the dry Siberian monsoon brings clear skies; snowfall is light but lies frozen for months on the frigid plain.
Changchun is fairly dry, receiving around 550–600 mm of precipitation a year, overwhelmingly concentrated in the summer months from June to August, while the long winter is very dry with only light snowfall. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.
Changchun's weather is governed by the seasonal reversal of the monsoon: the dry, frigid Siberian winter monsoon brings months of clear, bitterly cold weather, while the summer monsoon delivers a brief warm, humid, rainy season. The huge swing between deep winter cold and warm summers — a range of more than 35°C between the coldest and warmest months — is characteristic of this deeply continental corner of Northeast China.
