Qingdao and Shanghai are both coastal cities. Why is Shanghai sultry and Qingdao cool and pleasant?

Shanghai has a subtropical maritime monsoon climate. The main climatic characteristics are: warm in spring, hot in summer, cool in autumn and cold in winter, moderate annual rainfall and relatively even seasonal distribution. Generally speaking, the climate is mild and humid, with four distinct seasons.

The highest temperature in Shanghai is in July and August. In recent years, the summer in Shanghai is getting hotter and hotter, and the number of high temperature days exceeding 35℃ is about 10 days. 1Late October to early February (usually during the Spring Festival) is the coldest time in winter. Although there are not many days of sudden cold (usually lasting three days), the wet cold in the south of the Yangtze River is too much for northern Renye Fang, and the biting north wind often blows. Don't wear some heavy warm clothes, gloves, scarves and hats should be fully armed. There are not many days of snow, sometimes it doesn't snow all the year round. March to May is the best tourist season in full bloom in spring. What needs special reminder is that the rainy season is from mid-June to early July, both sunny and rainy. The rainfall of more than 20 days accounts for about 1/4 of the whole year, so it is not suitable to travel during this period. From the end of August to the middle of September, typhoons are frequent, and there are often downpours. You must take a sun umbrella to Shanghai during these two periods. Fortunately, the climate is hot at this time, and sunny days can also be used as sun protection. Qingdao is located in the north temperate monsoon region and belongs to the temperate monsoon climate. Due to the direct regulation of the marine environment and the influence of southeast monsoon, ocean current and water mass from the ocean surface, the urban area has obvious maritime climate characteristics. The air is humid, the temperature is moderate, and the four seasons are distinct. The temperature rises slowly in spring, which is later than inland 1 month. Summer is hot and humid and rainy, but there is no heating; In autumn, the weather is refreshing and there is little precipitation; In winter, the wind is strong and the temperature is low, which lasts for a long time, but there is no severe cold. Qingdao is located on the coast of the Yellow Sea and is obviously influenced by the marine climate. The annual average temperature 12.3℃, and the high-temperature weather with the daily average temperature higher than 30℃ rarely occurs, so there is no intense heat in Qingdao, but the winter in Qingdao lasts for a long time, the temperature is low, often accompanied by strong winds, the average temperature is -0.9℃, and the temperature rises slowly in spring.
