Glaciers have been regularly measured in Slovenia since the 1950s, but its snowfields have never been measured regularly. Therefore, this work presents the first such analysis. For the measurements of its areas, I used freely available photogrammetric, lidar and satellite imagery (Sentinel-2) from various sources such as the PISO, the Atlas okolja, the Google Earth Pro and the SentinelHub Playground. I measured its areas directly in the programs where this was possible or I used the program ArcMap. I measured eight snowfields in the Julian and the Kamnik-Savinja Alps for 12 different years from 2006 to 2022. Additionally, for the biggest snowfield the Amfiteater, I measured interannual variability of its area for two melting periods of 2021 and 2022. In total I measured 116 areas of different snowfields. I analysed the decline of individual snowfield and compared them with each other and with existing data from the Triglav glacier. The changes of areas of the Julian Alps snowfields between different years are comparable to those of the Triglav glacier. All snowfields are decreasing and are affected by changes in average temperatures.
