Weekend warmth from North African air mass
A warm air mass originating from the coasts of North Africa will affect Greece during the upcoming weekend. Daytime temperatures are expected to reach 32°C in several areas, creating conditions that still feel summery. The warmth will be most noticeable across the mainland and western regions. The coming two-day period features this warm air mass that raises the mercury noticeably, delivering a final summer-like sensation before the shift. Local showers remain possible over the Ionian Sea and afternoon instability may produce brief downpours in the mountainous parts of the mainland. Winds will stay strong from the north across the central and southern Aegean, reaching 6 Beaufort in exposed spots. Conditions stay generally mild overall, though strong northerly winds persist in the central and southern Aegean while isolated showers cannot be ruled out in the Ionian and limited afternoon instability may bring showers to mainland mountains. The warm air mass brings a noticeable rise in temperatures that reaches 32°C locally and sustains mild conditions across much of the country for the weekend period.
Conditions remain mild until Monday
The mild pattern is forecast to continue through Monday with only gradual changes. Cloud cover will stay limited, and any showers will remain isolated and confined to higher terrain during afternoon hours. This period offers a final stretch of warmer weather before the transition begins. The mild weather holds steady until Monday, with limited cloud and only isolated showers possible on higher ground in the afternoons. The pattern provides one last interval of the warmer regime ahead of the change that follows. Limited cloud amounts and isolated afternoon showers on higher terrain continue to characterize the mild conditions holding through Monday.
Cold air arrives from eastern Europe midweek
From the middle of the following week, colder air masses moving south from eastern Europe will reach Greece. The change will be abrupt, with temperatures falling below the seasonal average and producing a distinctly autumnal feel across much of the country. Northern and eastern districts are likely to see the strongest cooling and the highest chance of rain. The overall pattern will shift toward more frequent cloud cover and unsettled conditions. The mild weather ends after Monday when cold air masses from eastern Europe move in around midweek. This produces a real drop in temperatures to levels below normal for the season and turns the scene fully autumnal, with noticeably cooler conditions and higher rain chances mainly affecting northern and eastern parts of the country. The abrupt arrival of colder air after Monday creates below-normal temperatures and increases rain probabilities especially in northern and eastern Greece.
Wind and cloud patterns during the transition
During the colder phase, winds in western areas will turn variable at 3 to 4 Beaufort. Eastern regions will see northerly winds of 4 to 5 Beaufort, locally reaching 6 Beaufort in the Aegean. Cloud amounts will increase, especially over the mainland during midday and afternoon periods, with isolated showers possible over mountains. Few clouds will increase temporarily at midday and afternoon hours mainly over the mainland, where local rain or showers remain possible in the mountains. Winds turn variable 3 to 4 Beaufort in the west and northerly 4 to 5 Beaufort in the east, locally 6 Beaufort in the Aegean once the colder air arrives. The shift brings variable lighter winds to the west and stronger northerlies to the east while clouds build over the mainland with possible mountain showers.
