Foshan weather belongs to the subtropical monsoon humid climate zone, with a mild climate and sufficient rainfall. The annual average temperature is 22.5 ℃.
January is the coldest month of the year with an average temperature of 13.9 ℃.
July and August are the hottest months with an average temperature of 29.2 ℃.
The annual rainfall is 1681.2 mm (Sanshui 1688.7 mm, Nanhai 1677.4 mm, Shunde 1677.6 mm.
The hilly and mountainous areas in the west and north have a little more rainfall due to topographic uplift), with an average annual rainy day of 146.5 days.
The rainy season is mainly from April to September, during which the rainfall accounts for 80% of the total rainfall of the whole year.
The rainfall in summer is uneven, and the rainfall in autumn and winter is significantly reduced.
The duration of sunshine is 1629.1 hours and the growth period of crops is long.
Due to the low latitudes, the ocean and land weather systems have an obvious impact on Foshan.
The alternation of winter and summer monsoon is the prominent feature of Foshan’s monsoon climate: more northerly wind in winter and spring, and more southerly wind in summer.
The northerly wind in winter is formed by the polar continental air mass stretching southward, and it is dry and cold; the southerly wind in summer is formed by the tropical ocean air mass expanding northward, which is warm and humid.
Foshan weather in Spring
In the spring of Foshan, the temperature and precipitation are both in the rising period, which is the season where cold weather and warm weather alternate, so the instability is very large.
Spring in Foshan is normally cloudy and rainy.
Due to the lack of sunlight, the daily temperature changes are small. Of course, there were exceptions.
In some years there were warm spring with bright sunlight, and in some years, due to the late arrival of the rainy season, there were persistent droughts.
Usually, the rainy season starts in April and the city enters the pre-flood season.
Due to the influence of marine air mass, the south wind prevails in Foshan in summer, and abundant water vapour is continuously transported to the sky with the southerly wind, which provides favourable conditions for summer rainfall.
May and June are the peak rainfall periods in the pre-flood season of Foshan, and there are thunderstorms from time to time.
June to October is the main period for tropical cyclones affecting Guangdong.
According to statistics, there are usually 5 to 6 tropical cyclones that affect Guangdong every year, 3 to 4 of which will land in Guangdong, accounting for 40% of the number of tropical cyclones landing in China.
Therefore, summer is a season of thunderstorms and tropical cyclones accounting for 50% – 60% of the annual rainfall.
However, the summer rain is often what people are looking forward to.
Foshan has a long summer and hot weather.
The hottest months of the year is July and August, and the city’s average temperature reaches 29.2°C.
The extreme maximum temperature once appeared 39.2℃ (July 18, 2005, Nanhai District).
The high temperature in the summer season, coupled with the high relative humidity, makes the summer heat feel even hotter making us all secretly wish for more rain to cool us off!
Foshan weather in Autumn
Autumn is the most comfortable season of the year.
At this time, the cold air begins to go south and the temperature gradually drops.
Autumn is not the season of active tropical cyclones, but there is still the possibility of one or two with an average of a tropical cyclone will land in Guangdong every 10 years or so.
In general, autumn is mainly sunny with little precipitation.
According to statistics, the average precipitation from late September to the end of November is only 155.1 millimetres, accounting for about one-tenth of the annual rainfall.
Records show there have been years without rain for 30 consecutive days during Autumn.
The northeast and north winds prevail in Foshan in winter.
The cold and dry air masses from the north travels a long way, and their power is greatly weakened.
At the same time, as the ground temperature gradually increases, the original cold and dry nature of air masses gradually change to the colder and wetter nature, and the air pressure difference also decreases when reaching Guangdong, so the wind speed gradually decreases from north to south.
Winter is the dry season in Foshan, with less precipitation, fine weather, and sufficient light.
January is the coldest month, with a monthly average temperature of 13.9 ℃.
The lowest temperature recorded was – 1.9 ℃, on January 17, 1967.
Foshan weather statistics
Foshan’s annual average temperature: 22.5℃;
Annual average maximum temperature: 26℃;
Annual average minimum temperature: 19℃
Average annual rainfall: 1314 mm
