Greece braces for hot week with heatwave conditions

Greece is anticipating a week of significant heat, with temperatures expected to climb towards 40 degrees Celsius in several regions. Despite summer nearing its end, the country faces a prolonged period of high temperatures, creating conditions of intense heat.

Meteorological models indicate an approaching heatwave that will maintain very high temperatures for an extended duration. Dr. Michalis Sioutas, a meteorologist, described it as a "late August heatwave" that will make an appearance. In central Athens, the thermometer already registered 37 degrees Celsius, with increased humidity exacerbating the discomfort.

The coming days are predicted to be challenging, particularly for those working outdoors. Experts are advising increased caution for the elderly and other vulnerable groups during this period. Meteorologist Thodoris Kolydas noted that while heatwaves in the third week of August are not common, they are not unprecedented in Greece's history.

a late August heatwave will make its appearance.

Historical records show severe heatwaves, such as the one from August 20-26, 1958, when temperatures reached 47.2°C in Trikala and 45°C in Larissa, with Athens recording 43.6°C. Similar episodes occurred in 2006 and 2007 with temperatures exceeding 42°C in various areas. However, current forecasts do not suggest such extreme peaks.

The primary characteristic of the upcoming heat event is expected to be its duration rather than exceptionally high temperatures. In Larissa, a city with a history of intense heatwaves, seven consecutive days above 40°C were recorded in 1958. Current predictions for Larissa suggest maximum temperatures between 36–40°C, with the prolonged nature of the heat being the main factor. The absence of rainfall is also contributing to a dry and hot period.

In Athens, forecasts align on maximum temperatures around 37–38°C, with no immediate indication of exceeding 40°C. However, nighttime temperatures are also expected to remain high, around 28–29°C, offering little relief and increasing thermal stress for the urban population. The defining feature of this heat event is its persistence, rather than reaching extreme historical highs.

heatwaves in the third week of August are not common, but they do not constitute an unprecedented phenomenon for Greece.
