Based on the homogenized daily data in 2419 stations in China from 1961 to 2017, we calculated 26 extreme temperature and precipitation indices as defined by the Expert Team on Climate Change Detection and Indices (ETCCDI), and analyzed the characteristics of extreme temperature and precipitation in China in 2017. For China average, all the high temperature indices in 2017 were above the 30-year average of 1961—1990 and the extreme low temperature indices were lower than their corresponding 1961—1990 average. The annual minima of daily maximum temperature (TXn) and daily minimum temperature (TNn) reached the highest recorded value, while the number of cold nights (TN10p), cold days (TX10p), and cold spell duration index (CSDI) reached the lowest recorded value. Some indices were ranked at the second or third place since 1961, including annual maxima of daily maximum temperature (TXx) and daily minimum temperature (TNx), warm nights (TN90p), frost days (FD), icing days (ID), tropical nights (TR), and growing season length (GSL). Other extreme temperature indices were ranked in the top 10 since 1961. Meanwhile, 7 out of 10 extreme precipitation indices averaged over China in 2017 were within the range of one standard deviation of precipitation indices during 1961-2017, indicating a normal situation for extreme precipitation in 2017.
