Because it is cold and there are few tourists, it provides convenience for photography enthusiasts

The general characteristics of Zhejiang’s climate are: significant monsoon, four distinct seasons, moderate annual temperatures, more sunlight, abundant rainfall, humid air, and hot and rainy seasons. Changes are synchronized, climate resource allocations are diverse, and meteorological disasters are numerous. The annual average temperature in Zhejiang is 15~18℃, the extreme maximum temperature is 33~43℃, and the extreme minimum temperature is -2.2~-17.4℃; the province's average annual rainfall is 980~2000 mm, and the annual average sunshine hours are 1710~2100 hours. In spring, the East Asian monsoon is in the alternating season between winter monsoon and summer monsoon, with frequent intersections of north and south airflows, and intensified low pressure and frontal activities. The climate in Zhejiang in spring is characterized by cold and rainy weather. Strong winds often occur along the coast and offshore areas. Rainfall increases throughout the province, and the weather is unpredictable. As the saying goes, "The face of a child in spring changes three times in one day." The average spring temperature in Zhejiang is 13~18℃, and the temperature distribution is characterized by decreasing from inland areas to coastal and island areas; the province's precipitation is 320~700 mm, and the precipitation distribution is gradually decreasing from the southwest to the northeastern coastal areas; the province's rainfall is Days range from 41 to 62 days. The main meteorological disasters in spring include heavy rain, hail, strong winds, late spring cold, etc.

In summer, with the establishment of the summer monsoon circulation system, southeasterly winds prevail in Zhejiang. The subtropical high pressure activity in the northwest Pacific has an important impact on the weather in Zhejiang, while the cold air from the north and south still has a certain impact on the weather in Zhejiang. In early summer, various parts of Zhejiang gradually enter the flood season, commonly known as the "Meiyu" season. The probability of heavy rains and heavy rains increases, which can easily cause floods. In midsummer, affected by the subtropical high pressure, Zhejiang is prone to sunny, hot and dry weather, causing droughts. Summer is affected by tropical storms. The period with the highest probability in Zhejiang. Zhejiang's summer climate is characterized by high temperatures, heavy precipitation, strong sunlight, humid air, and frequent meteorological disasters. The average summer temperature in the province is 24-28°C, and the temperature distribution is characterized by decreasing from the central area to the surrounding areas; precipitation in various places is 290-750 mm, with more precipitation in the eastern mountainous areas, such as Tiantai Mountain, Yandang Mountain, Siming Mountain, etc., islands and central areas There is relatively little precipitation in the region; there are 32 to 55 rainy days in various parts of the province. The main meteorological disasters in summer include typhoons, heavy rains, droughts, high temperatures, thunderstorms, strong winds, tornadoes, etc. In autumn, the summer monsoon gradually weakens and transitions to the winter monsoon. Cyclone activities are frequent, there is more frontal precipitation, and the temperature changes greatly. Zhejiang's autumn climate characteristics: In early autumn, Zhejiang is prone to drizzling rainy weather, commonly known as "Autumn Lazarus"; in mid-autumn, controlled by high-pressure weather systems, Zhejiang is prone to clear autumn weather with clear skies and clear winds, which is the so-called "Autumn Lazarus". The weather of October is "Indian Spring"; in late autumn, the influence of cold air from the north begins to increase. The weather changes between cold and warm, sunny and rainy frequently, and the temperature fluctuates greatly. The average autumn temperature in the province is 16 to 21 degrees Celsius, with the southeastern coastal and central areas having higher temperatures and the northwest mountainous areas with lower temperatures. Precipitation ranges from 210 to 430 millimeters. The coastal mountainous areas in the central and southern areas receive more precipitation. Although precipitation in the northeastern region It is slightly less, but its inter-annual variation is large; there are 28 to 42 rainy days in various parts of the province. The main meteorological disasters in autumn include typhoons, heavy rains, low temperatures, rainy weather, heavy fog, etc.

In winter, the strength of the East Asian winter monsoon mainly depends on the activity of the Mongolian cold high pressure. The weather in Zhejiang is subject to the influence of the northern cold air mass (i.e., the winter monsoon), and there are relatively few types of weather processes. Zhejiang's winter climate is characterized by sunny, cold, less rain, and dry air. The average winter temperature in the province is 3 to 9 degrees Celsius, and the temperature distribution is characterized by decreasing from south to north and from east to west. The precipitation in various places is 140 to 250 mm. Except for the islands in the northeast, there is little difference in other places. There are 28 to 41 rainy days in various parts of the province. The main meteorological disasters in winter include cold waves, freezing damage, strong winds, heavy snow, heavy fog, etc.
