Tianjin, a major port city and municipality in northern China, sits on the coast of the Bohai Sea near the mouth of the Hai River, just southeast of Beijing, at approximately 39.13°N, 117.20°E. It has a monsoon-influenced humid continental climate (Köppen Dwa) — with cold, dry winters and hot, humid, rainy summers — similar to Beijing but slightly moderated by its position on the Bohai Sea.
Summer, from June to August, is hot and the wet season, with July the warmest month — average highs around 30–31°C and humid conditions. The East Asian summer monsoon delivers the great majority of the year's rain in these months, often as heavy downpours and thunderstorms, and the combination of heat and humidity can feel oppressive. Spring and autumn are drier and more pleasant.
Winter, from December to February, is cold and dry, with January the coldest month — average highs around 2°C and lows near -7°C, driven by the dry Siberian monsoon that brings clear, sunny but cold days. Snowfall is scarce, and the season is marked by cold, dry winds; early spring can bring dust and sand blown in from the north and northwest.
Tianjin is fairly dry, receiving around 520–560 mm of precipitation a year, overwhelmingly concentrated in July and August, while the rest of the year — especially winter — is dry. The summer rains can be intense enough to cause localised flooding. Live rainfall, humidity, and pressure readings for the city are shown in the panels above.
Tianjin shares the northern Chinese monsoon climate of nearby Beijing — hot, rainy summers and cold, dry, sunny winters — with the summer rains sharply concentrated into July and August. Its coastal position on the Bohai Sea lends a touch more humidity than the capital, while spring dust and sandstorms blown from the northern deserts are a recurring seasonal nuisance.
