The climate of the Třeboň basin is influenced by the adjacent Šumava highlands, by the flat surface relief of the basin itself, and by the thermal properties of the vegetation cover alternating with water bodies (Švec et al., 1967, 1969). In the climatic division of Czechoslovakia, the Třeboň region is classified as moderately warm (Quitt, 1971). Despite the oceanic character of the basin, which was originally a wetland, the distribution of precipitation is typical of Central Europe with abundant rainfall in summer (see the climatic diagram in Fig. 1 and Table 1). The air temperatures are positively affected by the heat capacity of the larger fishponds, whose water accumulates heat. Temperature inversions occur fairly frequently, being a product of cloudless nights combined with lack of wind in the rather flat landscape configuration of the Třeboň basin. The subalpine föhn blowing from the southwest sometimes affects the Třeboň region as well. Local thunderstorms are frequent in summer.
