Since the Kredarica station lies at the altitude of 2514 in, delay occurs and so, February is colder than January, August is as warm as July, and September by 4.00C warmer than May.

Since this station is located on the top of a ridge, and therefore more windy, its temperatures are slightly lower than on the less windy, lee location. But in the time of calms -- the average number of days with registered calms is 19 per month, the greatest number (25.9 days) in August -- the near-to-surface layer of air on the glacier frequently drifts downwards because it is heavier and so cooler air drops on the glacier from the cooler surrounding slopes.

According to Melik (1959, p. 157), in the fifties of this century the permanent snow line on Triglav was on 2550 m above sea level, which is 36 in above the meteorologic station. The average temperature of 3.70C in months of ablation and the average temperature of 5.00C in summer months would rank Kredarica among the warmest stations by the snow line. With the annual temperature of -1.70C it would rank somewhere in the middle between the warmest and the coldest ones (see: Wilchelm, 1975, pp. 99-104, and Gams, 1959, p. 137). But, besides temperature, total amount of snow precipitations and insolation are important. Although the glacier gets extra snow, the temperature of the warmest month (which is supposed to be equal on the climatic snow line from the North pole to 300C of the North latitude, i.e. 4.50C/Wilcheim, 1975/) at Kredarica seems to be too high, i.e. 5.80C. In most of the post-war years, the snow line was supposed to be at about 2700 m (Gams, 1960).
