According to Thodoris Kolydas, “from midweek, significant rainfall is forecast, mainly in the west and north.” The Star Channel meteorologist stated in a post:

“A few showers will start in the west and south, and by Wednesday in the eastern mainland, the northern Aegean islands, the Sporades, and Evia.
On Thursday, we’ll see more rainfall, while on Friday the weather phenomena will intensify, affecting the Ionian, Epirus, western Central Greece, and northwestern Peloponnese, gradually extending to central and northern regions.
Temperatures will drop slightly by 2–3 degrees, and winds will not exceed 5–6 Beaufort.”

“An Autumn from the Past”

Meteorologist Giorgos Tsatrafilias wrote in a post:

“With scattered light rain (except in the Aegean islands and Thrace) and cloudiness, the weather will progress until Thursday, October 16, 2025.
Temperatures throughout the week will remain near seasonal norms, providing thermal comfort.
A ceiling of 22°C in lowland areas and single-digit lows overnight and early morning in mountainous regions of central and northern Greece.”
He adds:
“From early Friday, a well-organized weather system affecting neighboring Italy seems likely to bring more rain and strong southerly winds to western Greece. This system will be evaluated in the coming 24 hours.”

In a postscript, Tsatrafilias notes:

“In Attica, I don’t expect anything significant. Temperatures will range between 11–23°C.”
