The spatial and seasonal precipitation variability in eastern Fujian was studied using the monthly precipitation data from 1985–2014, the Mann–Kendall (M–K) statistical test method, the periodic test method, and the Pearson type Ⅲ curve. The following conclusions were drawn: (1) There are obvious regional differences in the precipitation in eastern Fujian; more precipitation is found in the northern and western parts of eastern Fujian, while less precipitation is observed in the mid-eastern and western parts. In addition, Zherong Precipitation Center has the largest annual precipitation. (2) The precipitation in eastern Fujian fluctuates annually, but the variation is not significant, and the amount of precipitation is rather stable. The monthly precipitation shows bimodal characteristics, and the monthly distribution is uneven. (3) Strong precipitation in eastern Fujian mainly occurs from May to August, and the monthly difference in the frequency of strong precipitation in the north and mid-west is larger during the active period for strong precipitation, while the monthly difference between the eastern and western regions is smaller. The research results are important as a guide to the significance of the behavior of hydrological elements in eastern Fujian, to assist related departments in preventing mistake from floods, and to realize the sustainable utilization of water resources in the basin.
