Nights are cooler, often dropping to around 18° to 20°. Rainfall is quite common during this period, as Shanghai enters its plum rain season, known locally as "Meiyu." This results in frequent, sometimes heavy, showers and overcast skies.

As the month progresses, temperatures steadily rise. By mid-June, daytime temperatures typically range from 26° to 29°, and humidity levels increase, making the air feel warmer and more oppressive.

The city often experiences short bursts of intense rainfall, which can lead to temporary flooding in low-lying areas.

Towards the end of June, Shanghai's weather becomes distinctly summer-like. Daytime temperatures can soar to between 30° and 33°, with nighttime temperatures rarely dropping below 24°. The humidity remains high, contributing to a sticky and uncomfortable atmosphere.
