Mini-heatwave forecast on Monday, Tuesday

High temperatures will start to rise from Monday, when they are forecast to reach 37-38C, especially in western parts of the cuntry, before peaking at about 39C on Tuesday. The hottest regions will be in Attica, central Greece, Thessaly and urban areas that are not near the sea.
This is the first time that temperatures will climb so high this summer, though meteorologists say the phenomenon will not last long enough to be classed as a full-blown heatwave, which requires at least three days of high minimum and maximum temperatures.
In fact, Saturday and Sunday are expected to be slightly cooler than Friday by one or two degrees, as a result of northerly breezes, and temperatures are expected to subside again from Wednesday.
