The summer of 2022, in southwest Romania, as in Romania and on the European continent, was particularly hot, marked by a progressive weather warming starting from the very last month of spring - May. According to the Hellmann criterion, June was warm (CL) with a monthly mean of 22.06°C and a deviation from normal of 2.65°C. July was warm (C) with a monthly average, for the entire Oltenia region, of 23.96°C and a deviation from normal of 2.45°C. August was warm (C) with a monthly mean of 23.59°C and a deviation from normal of 2.5°C. Summer was hot (C) with a seasonal mean of 23.2°C and a deviation from normal of 2.5°C. The heat waves had the temporal extension of 51.1% of the summer days, and after the 7.VIII a rainy period followed. The entire continent of Europe was affected by the drought and then by the rainy season. The paper analyses the climatic evolution of this summer, which was the third warmest in the history of the climate in Oltenia, and is useful to all those interested in the climate of south-western Romania.

The periods of warming and cooling of the weather on Earth followed one another with great irregularity and caused significant variations in air temperature but allowed the existence of life and especially of the human species. In this paper we have analysed the variation of air temperature in Oltenia in the period 1961-2021. A number of our other works have analysed the variability of the climate in this part of Romania. After the warm period of 1945-1955, a gradual cooling of the weather followed in summers and during the period 1966-1984 (for 20 years). In summers, no thermal maximum of ≥40°C was registered. The period 2000-2021 (22 years) was the warmest of all the meteorological observations in Oltenia and many annual, monthly and daily climate records were surpassed. At the same time, during the analysed interval, the melting rate of the ice in the polar areas intensified a lot and exceptional thermal maxima were registered. The heat waves during the summers were more and more intense, more frequent and longer in duration. The paper is useful to all those interested in climate variability in Oltenia.
