What month is the best weather in Guangzhou?

Guangzhou, including urban area, Panyu city, Zengcheng county, Huaxian county and Conghua county, is located at 112 degrees 57 minutes-114 degrees 3 minutes east longitude and 22 degrees 35 minutes-23 degrees 35 minutes north latitude, and belongs to the south subtropical monsoon climate zone. According to the meteorological data of the Institute of Applied Meteorology of Guangzhou Meteorological Center for 4 years, the climate characteristics in Guangzhou are as follows:

Guangzhou is located at low latitude, and the surface receives more solar radiation. At the same time, due to the influence of monsoon, the ocean warm air flow forms a high temperature, high humidity and rainy climate in summer; In winter, the cold wind in the northern mainland forms a climate of low temperature, dryness and little rain.

1. temperature: the annual average temperature is 21.4-21.9 degrees, 21.4 degrees in the north, 21.7 degrees in the middle and 21.9 degrees in the south. The hottest July-August, the average temperature is 28.-28.7 degrees, and the absolute maximum temperature is 38.7 degrees; The coldest is January (February in some years), the average temperature is 12.4-13.5 degrees, and the absolute lowest temperature is-2.6 degrees. The average temperature rises gradually from January to July every year. Frost may appear from late November to mid-February.

second, rainfall: the average annual rainfall is 1 623.6-1 899.8mm, which is more in the north than in the south. Every year, the rainfall increases gradually from January, and increases sharply in April. The rainfall is the highest in May-June, mainly in the flood season from April to September, and October to March of the following year is a rainy season. The first flood season from April to June is mostly frontal rain, and the second flood season from July to September is mostly tropical cyclone rain, followed by convective rain (hot thunderstorm).

illumination: (1) the annual average solar radiation value is 4,367.2-4,597.3 mj/m2, and the distribution is high in the south and low in the north. During the year, the solar radiation was the lowest in February and the highest in July. (2) The average sunshine hours for several years is 1,82-1,96 hours, and the annual sunshine percentage is 41%-44%, with more in the south and less in the north. Seasonally, summer is the most, followed by autumn, winter again, and spring is the least.

4. Wind: Due to the influence of monsoon, South China is controlled by cold high pressure in winter (January) during the year, with northerly winds and northeast winds; In spring (April), the wind direction is messy, but the southeast wind is more; In summer (July), influenced by subtropical high and South China Sea low, southerly winds predominate; Autumn (October) changes from summer monsoon to winter monsoon, with northerly winds as the main trend. In terms of average wind speed, the wind speed is higher in winter and spring and lower in summer. However, tropical cyclones often attack in summer, and the wind speed can increase sharply to a gale of magnitude 8 or above.
