The objective of the work is to determine the periodicity and trends of change in air temperature and precipitation in Poland in the time period of the 18th-20th centuries, together with the forecast for the 21st century. There are interesting diagrams of the temporal changes of solar activity and North Atlantic Oscillation (NAO) indicator, with the forecast reaching the year 2100. The forecasts were obtained on the basis of interpretations of the Wolf number and NAO indicator cycles, determined with the method of “regression sinusoids”. The fluctuations of the air temperature and precipitations during winter in Warsaw and in Cracow are closely correlated.
