One thermometer in central Athens showed a reading of 42 degrees (107.6 Fahrenheit) celsius in the sun.
Athens officials opened air conditioned centres for the elderly and the country's civil protection service warned of areas at high risk of fires.
In the first heatwave of the summer for Greece, tourists found relief under trees, umbrellas and at fountains.
Meteorologists said temperatures were expected to subside over the next days.
