Based on the climate data and the social statistics of Guangzhou observatory from 1952 to 2014，this paper used Linear trend analysis, Morlet wavelet transform analysis, Mann-Kendall mutation test etc, to analyze the trend of climate change in Guangzhou nearly 65 years. The results showed that climatic conditions in Guangzhou in recent 65 years showed a warming and drying trend and this trend had become increasingly apparent since the 1990s. The average temperature increased at the rate of 0.153 ℃ / 10a , at the same time, the warming rate of average minimum temperature was higher than the average maximum temperature (0.15 ℃ / 10a> 0.14 ℃ / 10a). The annual precipitation had a slight increase at the rate of 37.77 mm / 10a. Under the effect of urban dry-island, the average relative humidity had a decreasing trend at the rate of 0.94% / 10a and the sunshine hours showed a decreasing trend with fluctuation.
