Dalian is close to the sea and has a temperate monsoon climate. At the seaside, the specific heat capacity of seawater is much larger than that of land, so the temperature of seawater rises slowly in summer and during the day, and the temperature is lower than that of land, which will blow the sea breeze; In winter night, the temperature of seawater drops slowly, and the temperature is higher than that of land, which will blow the land wind.

The typhoon season in Dalian should be mainly concentrated in July, August and September. Generally, a typhoon affects Dalian every year. Due to the high latitude and insufficient environmental conditions, the intensity of typhoons affecting Dalian is generally weak and cannot be compared with the super typhoon in South China. There are dozens of typhoons that have affected Dalian in history, and they are generally relatively small.

Dalian Meteorological Observatory issued the blue warning signal of gale at 05: 10: 02, 2020: It is predicted that the gust of northwest wind of level 6 in Bohai Sea, Bohai Strait and northern Yellow Sea will weaken to level 5-6 during the day and night on the 2nd, so please take precautions.
