Why is Hangzhou hotter than Suzhou?

The reason why Hangzhou is hotter than Suzhou;

1. Location: Hangzhou is located in the southwest of Zhejiang Province, in the Yangtze River Delta region, near the sea, and is greatly influenced by the ocean airflow. Suzhou is located in the middle of Jiangsu Province, far from the ocean, and is less affected by the ocean airflow.

2. Climatic conditions: Hangzhou is a subtropical humid climate with four distinct seasons, hot and humid in summer and relatively cold in winter. Suzhou has a subtropical monsoon climate, with relatively mild winters and hot and humid summers. Because the climate in Hangzhou is closer to the tropical climate, it is hotter in summer.

3. Urban construction and population density: Hangzhou is a fast-growing big city with a large population and relatively dense urban construction. High-rise buildings and urban heat island effect make the temperature inside the city relatively high. Although Suzhou is also a prosperous city, it is small in scale and relatively low in population density, and the temperature in the city may be slightly cooler than that in Hangzhou.
