Abstract. Climate change increased the variability of maximum and minimum air temperature and rainfall. Air temperature and rainfall, which are parts of weather components, have been become uncertain and may affecting soil moisture. The dry and wet season onset based on rainfall may resulted in different definition if using soil moisture. This research aims to analyze the difference between air temperature and soil moisture inline graphic as parameter of season onset. The climate and soil moisture data were collected from November 2016 to December. The climate and soil moisture data were collected from Jumantono weather station and soil moisture logger, respectively, in Karanganyar District, Indonesia. The results showed air temperature and soil moisture (maximum and minimum) patterns were different. The minimum soil moisture occurred in the dry season, but not the lowest minimum air temperature.
