The paper reports the reconstruction of monthly precipitation series in northern Poland. The source database comprised series from 12 stations, with data ranging from 1880 to 2008. Firstly, a reconstruction of the series was performed. Then the reconstructed series was subjected to a check of the homogeneity using the Standard Normal Homogeneity Test, which allowed detection of some inconsistencies present in the original data and introduced by the reconstruction process. In the last stage, the analysis of the long-term variability were presented. No significant negative trend was detected in the annual precipitation totals in the period 1880-2008.
