Rock-surface temperatures were measured on a tor and a large block located below the timberline in the Kobugahara Highlands in central Japan. The mean air temperature of the coldest month is − 4 °C. Rock-surface temperatures were recorded continually every 30 min from December 1, 2002 through December 13, 2004 by thermistor probes connected to miniature data loggers. The diurnal and the annual freeze–thaw cycles and effective freeze–thaw cycles were recorded at each site. The freezing index of rock-surface temperature showed a marked variability from year to year. In addition, differences in local conditions at observation sites within a given area greatly affected the rock-surface temperature. These are important considerations in relation to local weathering below the timberline
