The paper presents the results of meteorological measurements carried out in the Kaffioyra Plain in the summer season of 2003. The main meteorological observations were conducted in N.Copernicus Polar Station, situated in northern part of the Kaffioyra (NW Spitsbergen). The paper also presents the results of ablation measurements on the Waldemar Glacier and Irene Glacier, which are located at Kaffioyra Region. The mean air temperature in the summer period (21.07. to 31.08.2003) was 6.1°C and was visibly higher then the long-term average. The sum of precipitation in this time was 74 mm and was higher then the long-term average. The comparison between summer season 2003 and mean values from the years 1975-2003 in the common period shows that this season was characterised by air temperature higher then many year?s values. The Waldemar Glacier and Irene Glacier are located in the northern part of the Oscar II Land, northwestern Spitsbergen. In spite of small areas of these glaciers, there is great spatial variation of ablation. Both Waldemar Glacier and Irene Glacier area and the height difference between the accumulation zone and the ablation area are relatively small. Nevertheless, spatial variation of ablation is observed. In this summer season the highest ablation values of Waldemar Glacier were noted in the ablation area of the glacier up to the altitude of about 250 m a.s.l., as well as at the foot of its medial moraine. The highest ablation values of Irene Glacier were noted in the ablation area of the glacier up to the altitude of about 300 m a.s.l.. During the analysed season a high average air temperature was observed. It resulted in increased ablation if compared to the previous seasons. Average air temperature and local glacier conditions were accepted as the main factors of ablation. The glacier average total summer ablation of Waldemar Glacier was 118.1 cm w.e. And Irene Glacier 111.1 cm w.e., respectively. The main meteorological parameters, which have an influence on ablation, are air temperature, wind velocity, insolation and participation. But it must be stressed that these parameters are clearly determined by local conditions of glaciers such as hypsometry, solar exposition, slope as well as density and the course of supraglacial streams.
