岭南地区刚好位于南北气候交汇区和大陆与海洋过渡区。因此,岭南地区呈现出与中国国内其他地区与众不同的气候特征。
冬季(12~2月份) 普遍盛行东北风或北风,来自北方既寒冷又干燥的空气,经过长途跋涉以后,增温、增湿,强度大为减弱,到达广东时风速已经变小、气温偏高,所以冬季较温暖。但个别年份在寒潮来临时,也可出现霜冻天气。冬季是广州的干季,降水较少,多晴好天气,光照充足。
春季(3~5月份) 是过渡季节,气温和降水均处在上升时期。正因为这个时候是冷暖天气交替的变化季节,所以它的不稳定性很大。有的年份会出现春光明媚的春天,而有的年份却会出现持续的低温阴雨倒春寒天气;在某些年份因为雨季来得迟,可能出现持续性的干旱。但从常年的情况来看,雨季在4月份便开始了,各地先后进入前汛期。
夏季(6~8月份) 由于受海洋气团的影响,普遍吹偏南风,带来丰沛的雨水。6月份是广东前汛期的降雨高峰期,各地出现暴雨的机会甚多。同时,每年的6~10 月又是热带气旋影响广东的主要时段,影响广东的热带气旋,有89%以上出现在这个时段内。
秋季(9~11月份) 冷空气开始影响广东,气温逐渐下降。此时多晴朗天气,少降水,开始进入干季。热带气旋活动的次数减少。11月份虽不是热带气旋最活跃的季节但仍有出现的可能,平均10年有一个热带气旋登陆广东。

Lingnan area is just located in the North-South climate intersection area and the transition area between the mainland and the ocean. Therefore, the climate characteristics of Lingnan are different from those of other areas in China.
The northeast wind or north wind prevails in winter (December to February). The cold and dry air from the North increases temperature and humidity after a long journey, and the intensity is greatly weakened. When it reaches Guangdong, the wind speed has become smaller and the temperature is higher, so it is warmer in winter. But in some years, when the cold wave comes, frost weather can also appear. Winter is the dry season in Guangzhou, with less precipitation, more fine weather and sufficient light.
Spring (March to May) is the transition season, and the temperature and precipitation are in the rising period. It is precisely because this time is the alternation of cold and warm weather, so it is very unstable. In some years, there will be a beautiful spring, while in some years, there will be a continuous cold weather; In some years, persistent drought may occur due to the late rainy season. But from the perennial situation, the rainy season began in April, and all regions have entered the pre flood season.
In summer (June to August), due to the influence of ocean air mass, the southerly wind generally blows, bringing abundant rain. June is the peak period of rainfall in the first flood season in Guangdong Province, and there are many opportunities for rainstorms in various places. At the same time, June to October of each year is the main period of tropical cyclones affecting Guangdong. More than 89% of the tropical cyclones affecting Guangdong occur in this period.
In autumn (September to November), the cold air began to affect Guangdong, and the temperature decreased gradually. At this time, more sunny weather, less precipitation, began to enter the dry season. The number of tropical cyclone activities decreased. Although November is not the most active season for tropical cyclones, it is still possible for them to appear. On average, one tropical cyclone will land in Guangdong in 10 years.
