The Southwest Current prevailing in the lower levels of the atmosphere on the coast of Africa and the Central Mediterranean will carry warm air masses towards our region and will cause in Greece very high temperatures which will be maintained at least until Friday 19/7.

The highest temperatures will occur in the interior of mainland Greece (mainly in the west and north) and on the islands of the eastern Aegean Sea. In the coastal areas of the mainland the maximum temperature will be 2 to 4 degrees lower due to the sea breeze. Minimum temperatures will be high, especially from Monday 15/7 onwards.
