Based on early spring (February to April) daily temperature from 7 county observation stations in the southern Zhejiang from 1971 to 2015, according to meteorological disaster indexes of early spring frost for tea, the multiscale trend method is used to analyze the temporal and spatial characteristics of early spring frost for spring tea in the southern Zhejiang and the MannKendall test is applied to verify the trend, mutations and turning of early spring frost weather. The results show that the probability of early spring frosts occurred in the southern Zhejiang is high with an annual mean of 16.8 d/a; the highest occurrence probability in February, mainly consisting of minor and severe frosts; as for the spatial distribution of early spring frost, the probability increases from southeast to northwest, the lowest in Qingtian, and the highest in Jinyun. The longterm trend of early spring frost days for spring tea shows a significant decreasing trend, and the extreme minimum temperature rose significantly, with the possibility of early spring frost reducing in the southern Zhejiang. The mutation of early spring frost reduction occurred in the 1980s and 1990s in the southern Zhejiang, and the decreasing trend was the most significant in the early 21th century.
