The present paper is the third part of a series of scientific researches concerning the extreme or anomalous high temperature conditions over the Greek region focusing especially on the Thessaloniki area. After the study of the three heat wave events during the summer of 2007 and the analysis of the exceptionally high maximum (Tmax) and minimum (Tmin) temperatures that occurred during November 2010, we aimed on the investigation of the temperature conditions of September of 2011 in Thessaloniki. This month was characterized by large departures of maximum temperatures from the long term mean values, reaching up to almost 4°C. Especially in the case of minimum temperatures, September of 2011 was found to have the highest Tmin average in comparison to the reference period 1958–2000. Analogous results were found for several stations over the domain of study. These temperature conditions are expected to occur more than 50% of the time by the end of the twenty-first century, according to the comparison with the future projections of seven different regional climate models. It should also be highlighted that several days in September 2011 exceeded even the 75th percentile of the simulated data.
