coming from the deserts of Mongolia and of Central Asia, which forms a characteristic haze and brings breathing problems and eye irritation. On the other hand, when the wind is weak and the air is stagnant (a situation that occurs more easily in winter, while in summer, the heat makes the air rise, in addition, it can rain), the city can be affected by local smog.
, the temperature rapidly increases, so much so that it often exceeds 20 °C (68 °F) already in April, while in May, the average maximum is around 26 °C (79 °F), which confirms how early the weather becomes warm.
, then, in July and August, the maximum temperature does not increase any more because the summer monsoon arrives around mid-June, bringing rains, sometimes heavy, and high humidity. So, the summer in Tianjin is hot but especially muggy. July and August are the rainiest month.
Anyway, the monsoon is quite irregular, here as in the north-eastern part of China, so the rains may be more or less abundant depending on year.
, with highs about 35 °C (95 °F), and the perceived temperature even exceeding 40 °C (104 °F) because of the humidity. Occasionally, such as in late June 2022 and early July 2000, a real temperature of 40 °C (104 °F) can be reached. In the neighborhoods closest to the sea, however, the breeze tempers the heat a bit.
, the weather improves, rainfall decreases, and already in October, the rains become quite rare. By September, the humidity decreases and the temperature becomes pleasant, while in October, nights begin to be very cool.
in Tianjin shines quite often all year round. The least sunny months, at least when considering the length of the days, are July and August.

From July to early October (and occasionally also in the second half of June), Tianjin can be affected by
, the tropical cyclones of South-East Asia, although it is rarely hit, in fact typhoons generally affect Korea and the easternmost part of northern China, besides, at these latitudes they arrive weakened.
The best times to visit Tianjin are spring and autumn, in order to avoid both the cold of winter and the heat and the rains of summer, and in particular, from mid-April to mid-May and from mid-September to mid-October.
