General opinion prevails that touring in the Suwałki region is the vital function of this region. However, this is only partly true. Although very good conditions exists there for tourism development they are made use of in an inefficient and incorrect way. Therefore, e.g. touristic basis should be developed, sewage purification plants should be constructed in the towns and the unrestrained development of agriculture and industry should be prevented.
The aim of this thesis was to present the characteristic of precipitation conditions in Suwałki Lake District. Analysis was made on the base of daily sum of precipitation of six meteorological stations during 1971–2000 period. Frequency of months and seasons with defi cit or excess of precipitation according to Kaczorowska’s criterion, frequency of non-precipitation day sequences >10, >15 and 20 days in the periods April–May, June– July, August–September and April–September were taken into consideration. Numbers of days with-precipitation ≥ 0.1 mm, ≥ 1.0 mm, ≥ 10.0 mm, ≥ 20.0 mm and ≥ 30.0 mm was analyzed also. All examined weather stations indicate that precipitation shortages are characteristic for the 90”s. Not only total precipitation amount indicate that, but also their classifi cation presented according to Kaczorowska as well as precipitation – free periods.
