The third coldest April since 2010: temperatures below the seasonal norm in April 2025 according to data from the National Observatory.
One of the coldest months of April on Crete
In April 2025, daily maximum temperatures across almost all regions of Greece stayed below average compared to the 2010–2019 period.
This trend was tracked by a network of 53 meteorological stations that have been operating continuously since 2010.
The following map shows how much average maximum temperatures deviated by region for April 2025:

Western Greece was the only area where the monthly average maximum temperature didn’t dip below the ten-year average.
Athens had a mean deviation of -1.1°C in maximum temperature.
Out of 30 days, 20 were cooler than what’s typical for the season.
Meanwhile, in Thessaloniki, 22 days came in below the seasonal average, with a monthly mean maximum temperature deviation of -1.4°C.
This coolness in temperatures was widespread and pretty notable in several parts of the country.
Spring returns to Crete with rising temperatures
Crete is finally seeing a shift back to milder spring conditions.
The weather’s mostly clear, but some clouds may pop up—mainly in the central and northern areas as the afternoon rolls in.
Temperatures are on the rise, especially in the eastern and southern parts of the island.
Daytime highs are expected between 20 and 23 degrees Celsius, which feels like a welcome change after the recent chill.In the middle of next week, temperatures are expected to reach around 28 degrees Celsius.
Winds are moderate, mostly blowing from the west, and can get a bit stronger in the southern coastal spots—up to 6 Beaufort.
This brings a refreshing breeze, though it might cause some extra clouds to build up inland.

Frequently Asked Questions
What were the recorded temperature lows in the Aegean Islands and Crete in April 2025?
Temperatures fell to some pretty low levels across the Aegean Islands and Crete in April 2025.
In some spots, minimums got close to freezing—especially overnight. Exact numbers varied by location, but they were definitely below the usual April averages.
How does April 2025 compare to other cold Aprils in the Aegean Islands and Crete since 2010?
April 2025 comes in as the third coldest on record in the Aegean Islands and Crete since 2010.
Only two other Aprils in the last fifteen years were colder, so it’s up there among the most significant cold weather events for these regions.
What weather conditions caused the cold temperatures in the Aegean Islands and Crete in April 2025?
The cold spell was the result of persistent high-pressure systems and cold air masses drifting down from the north.
This brought cooler winds and kept warm air from moving into the Aegean and Crete. Fewer clouds at night also meant more heat escaped after sunset.
Were there any specific weather events linked to the cold snap in the Aegean Islands and Crete in April 2025?
Yeah, there were a few. The cold wave brought sporadic frost and even some snow at higher altitudes—pretty rare for April, but it definitely reinforced the chill all month long.
How did the low temperatures in April 2025 affect farming in the Aegean Islands and Crete?
The cold weather delayed crop growth and damaged some early-season plants.
Farmers reported frost-related losses in vineyards and fruit orchards, and the freeze also hit outdoor vegetables in certain spots—so local food production took a bit of a hit.
