Corfu recorded an unprecedented 793mm of rainfall in November 2025, marking an historic record for the island over at least the past century. This extraordinary weather event was part of a broader pattern of significantly increased precipitation across Western Greece and Epirus during the month, as documented by the extensive network of automatic meteorological stations operated by meteo.gr / National Observatory of Athens.
November 2025: A Month of Record Rainfall Across Greece
According to data from meteo.gr, November 2025 saw exceptionally high rainfall levels, particularly in Western Greece and Epirus. Four meteorological stations registered over 800mm of monthly rainfall, 13 stations exceeded 600mm, and 33 stations recorded more than 400mm. A remarkable 283 stations (51% of all active stations) reported rainfall totals exceeding 100mm.
The highest monthly rainfall was observed in Katarráktis, Arta, with 1055mm, despite minor data transmission interruptions. Epirus, especially the mountainous region of Tzoumerka, also experienced extreme precipitation, with recorded levels surpassing 1000mm within the month. The November 2025 rainfall figures for Katarráktis and Lepianá, Arta, are among the top ten highest monthly rainfall totals ever recorded since the inception of meteo.gr’s automatic weather station network.
These record-breaking figures align with other periods of intense weather phenomena: February 2019 (storms Chioni and Oceanis) and September 2023 (storms Daniel and Ilias). November 2025’s extreme weather has been attributed to storm Adel.
New Storm System Approaches Corfu and Ionian Islands
As of Monday evening, atmospheric instability is expected to increase, bringing rain and easterly winds of 3 Beaufort to Corfu. On Tuesday, intermittent heavy rainfall is anticipated throughout the day, accompanied by southeasterly winds reaching up to 5 Beaufort. Temperatures are forecast to reach a maximum of 17°C and a minimum of 11°C, with high humidity levels peaking at 95% by nightfall.
From Tuesday evening, a low-pressure system originating from Northwest Africa will begin to impact the Ionian Islands. This system is predicted to bring strong rains and gusty winds, locally reaching up to 7 and even 8 Beaufort. These intense weather conditions are expected to persist until Friday.
No African Dust Expected, Complex Weather Interaction
Despite the African origin of the low-pressure system, the transfer of African dust is not expected to affect the region. This is because cold air masses from Russia will move into the area, interacting with the warmer air. A large anticyclone over Siberia is shifting southward and westward, influencing Europe and Greece. This interaction of warm and cold air masses, combined with the low-pressure system, will lead to intense weather phenomena rather than cold temperatures.
Meteorological data indicates that on Wednesday, the low-pressure system will deliver significant rainfall to Corfu. The convergence of warm and cold air masses will generate Nimbostratus (Ns) and Cumulonimbus (Cb) clouds, both known for carrying large amounts of water. Cumulonimbus clouds, in particular, are also associated with strong gusty winds. The combination of these cloud types, high humidity, and the island’s topography will contribute to severe weather conditions.
