Greece is set to experience its second heatwave of the summer, with temperatures expected to reach as high as 42°C in some regions over the coming days. Meteorologists warn that vulnerable groups—including the elderly and pregnant women—should take extra precautions as the extreme heat sets in.

According to weather experts, Sunday and Monday will be the least intense days of the heatwave, with temperatures hovering around 38°C. The situation is expected to escalate on Tuesday and Wednesday, when the heat will peak. Areas particularly susceptible to high temperatures, such as the Thessalian Plain, parts of eastern Peloponnese, and the greater Athens area, will be most affected.

Urban discomfort is forecast to be particularly severe, as nighttime temperatures in major cities are not expected to drop to normal levels, making heat relief during the evening hours unlikely.

Expected Peak Temperatures in Key Areas:
• Serres: 40°C
• Kilkis: 40°C
• Larissa: 40°C
• Karditsa: 41°C – 42°C
• Trikala: 41°C – 42°C
• Lamia: 40°C – 41°C
• Thebes: 41°C
• Chalkida: 40°C
• Attica (Athens): 40°C
• Argos: 40°C
• Nafplio: 40°C
• Sparta: 40°C

The heatwave is expected to begin subsiding on Thursday. However, meteorologists caution that strong winds expected later in the week could significantly increase the risk of wildfires. “This is the second heatwave of the summer. Temperatures will remain high from Sunday through Wednesday, with inland areas potentially reaching 40°C, 41°C, or even 42°C, particularly on Tuesday and Wednesday,” noted the Director of Research at the National Observatory of Athens.

Saturday’s Heat Signals What’s to Come

Even before the official onset of the heatwave, Saturday saw temperatures climbing sharply. According to meteo.gr, thermometers reached 39–40°C in parts of western and northern Greece. Data from 70 automated weather stations operated by the National Observatory of Athens recorded maximum temperatures exceeding 37°C, underscoring the severity of the incoming heatwave.

Authorities urge the public to remain vigilant, stay hydrated, avoid unnecessary outdoor activity during peak hours, and check in on those most at risk.
