The weather has changed, with the temperature dropping from Thursday even by 10 degrees Celsius, while stormy north winds and rains will hit Greece. At the same time, the meteorologist Giorgos Tsatrafillias is even talking about snow.
Where will the temperature fluctuate?
For particularly low temperatures for the season until 23/10 is also the reason Weather forecast in his analysis of the evolution of the weather.
Specifically, according to the available prognostic data of meteo.gr / National Observatory of Athens, the high temperatures prevailing recently will show a gradual retreat. The drop in temperature is expected to be noticeable throughout the country and especially in Northern Greece.
According to the available data the air masses that will settle over our country from Friday 18/10 will be generally 4 to 6 °C cooler than normal prices for the season and locally in Northern Greece 7 to 8 °C colder than normal prices for the season.
Warmest and coldest scenario – See maps
In the images that follow, the range of temperature variation up to 23/10 at a height of approximately 1500 meters above Athens and Thessaloniki is shown indicatively.
With her red line shows the “warmest” scenario while with the blue line the “coldest” scenario. With green line shows the average temperature variation based on all available model scenarios.
Finally, the black horizontal line marks the approximate average value of the time according to data from the period 1991-2020. As it becomes apparent, almost all scenarios give temperatures lower than normal for the season.
“I don’t rule out even snow” – The post Tsatraphyllia
G. Tsatrafillias even sees snow in the coming days and especially on the weekend, as he mentions in his post.
Cold air is responsible for this change, which through Ukraine and Turkey will gradually begin to affect our country as well, culminating in the weekend.
As he specifically notes, the northerly winds from Thursday until at least the end of the week will blow stormy in the Aegean, while at the weekend the southerlies in the Ionian will have the same intensity.
What is true about the weather in Athens, Thessaloniki
The drop in temperature will be significant, especially during the weekend, adds Mr. Tsatrafillias. Indicatively, many areas of northern Greece will wake up with temperatures close to zero, while in the big cities (Athens, Thessaloniki, Patras, Ioannina) on the weekend when the sun goes down, a jacket will be essential!
As far as the rains are concerned – of course depending on the position of the low – for the moment they seem to be more in western Greece especially during the weekend.
“I do not rule out that in the very mountainous areas of northern Greece, we will have a few “sprinklings” of snow during the weekend!”, concludes the meteorologist.
Kolidas: Cold from Thursday, rains at the weekend
The director of EMY, Thodoris Kolidas, also sees a change in the weather since the middle of the week. “The presence of the subtropical cyclone off the coast of Africa from mid-week onwards will ‘steer’ the upper western European low towards our region and change the shape of the Ω-Block. This will result in rains, the SC mainly in western Greece” says the director of the EMY, Thodoris Kolidas.

Who is the Omega Blocker – How does it block the way in bad weather?
A weather different from the one we are used to for October will be brought by Omega Empodistis, with the temperature falling below the normal levels for the season, explains Klearchos Marousakis.
As he notes, “it is an extensive field of high pressure that spreads over a large part of the Old Continent, forming the capital letter omega of the Greek alphabet (first map) and which essentially closes the way to bad weather, forcing them to follow another route”.
The mercury is expected to drop even below normal levels for the season with the cold making its presence felt overnight and into the morning.
“The bad weather system we described in the previous paragraph needs a lot of monitoring since if it manages to “defeat” the anticyclone that blocks its path, it will arrive in our country with great energy and quite enriched with water vapor,” says the meteorologist.
