For the purpose of understanding climate of the glacier area of the northern side of the Himalayan range, a temporary station was set up at a height of 5055 m in Hidden Valley, Mukut Himal during the monsoon season of 1974. The temperature pattern, especially the trend of minimum temperature and the diurnal temperature range, seems to reflect the monsoonal character and to represent its effect better than the precipitation pattern. At the beginning and the end of the observation period, a rapid change of minimum temperature and large temperature range were recorded, as opposed to the stationary trend of mean temperature from the middle of July to the middle of August, which seems to be the monsoon season in Hidden Valley. At the station, most of the precipitation was in the form of rain and rain-snow mixed. Nocturnal precipitation was more than daytime precipitation, which was less than 5 mm. The daily mean of evaporation slightly exceeded the daily mean of precipitation even in the monsoon period. The diurnal variation of atmospheric pressure shows two maxima and two minima.
