Abstract Discovering climatic information from ancient dairies is one of the most important methods for the reconstruction of historical climate. Based on the weather records in the Gengzi Xinchou Diary written by Lü Zuqian in AD 1180 and 1181 of Southern Song Dynasty,the duration and rainfall of Meiyu Flood Periods(from May to June)in these two years in Jinhua area are reconstructed with the statistical regularities from the precipitation data measured in 1954-2012. It is found that both the Meiyu onset dates(MODs)in 1180 and 1181 are earlier compared with the average MODs of nowadays;the precipitation from May to June and the duration of Meiyu Flood Period are a little smaller and shorter than average in 1180,and larger and longer than normal in 1181. The results provided intuitive,favorable evidences for the records of drought and flood disasters during the two years in historical documents.
