The research studies the influence of seasonal climatic changes on the process of wood seasoning, explores the possibilities of increasing kiln drying capacity, and saving energy in technical processes of wood seasoning at a reasonable use of air drying. The process of wood seasoning was studied on 38 mm thick beech samples and monitored on 8 subsequent series from the beginning of December to the beginning of August. They were submitted to air drying in fresh state and seasoned until they reached balance with the environment. During air drying of wood the effects of temperature and relative humidity on drying curve and speed in different seasons were studied. The results show that the drying rate is most affected by changes of temperature. The highest drying rates were reached in May and June, the lowest in December and January. The drying rate decreased substantially in the event of a sudden drop of temperature, causing a sudden increase of relative humidity. Through a quality assurance process it was confirmed that the samples were seasoned well and without defects.
