The maximum temperatures in the warm period of the year register obvious upward trends. In the south of the Republic of Moldova, according to climate evolution scenarios, temperature is the main climatic element affected by climate change. To determine the duration, intensity and number of heat values, we used one of the methods often used in climatology – the percentile method. Thus, we found that the number of cases with maximum temperatures above 30°, 35° and 40°C recorded in recent years is higher than the multiannual average. The duration of heat waves has increased, the maximum values moving towards August, and the period of occurrence of hot periods has extended until September.
