Meteorologists Expect Hot Autumn and Mild Winter in Greece: Climate Forecast for the Mediterranean.
Long-term Weather Outlook for Greece
Table of Contents
Greece faces a warmer than usual autumn this year. The Greek Meteorological Service predicts temperatures could rise up to 2°C above normal from September through November. This follows an exceptionally hot summer, with July being the warmest month on record since 1860.
The warm trend may continue into winter, especially in western and southern regions. Along with higher temperatures, rainfall is expected to decrease. This combination could lead to water supply issues in 2025 if winter precipitation remains low.
Key points:
• Autumn temperatures: Up to 2°C above average
• Winter forecast: Likely milder than usual
• Rainfall: Expected to decrease
• Water concerns: Potential supply issues in 2025
It’s important to note that seasonal forecasts have a 40-60% accuracy rate. The situation may change as we approach the cooler months.
Nevertheless, we are already curious to see how the water problem on Crete will worsen next year if this prediction of a third dry winter is even mostly correct!
Greece’s climate varies by region:

Popular destinations like Athens, Santorini, and Crete typically enjoy mild winters. However, northern areas such as Thessaloniki can experience colder temperatures.
Sweltering September follows Europe’s summer heatwaves
Europe braces for an unseasonably warm September, extending the scorching temperatures experienced during the summer months. The continent, particularly its southeastern regions, endured intense heatwaves and drought conditions throughout the season. Now, as autumn approaches, the heat shows no signs of abating.
Meteorological forecasts predict mainland temperatures to soar 5°C to 8°C above the 30-year average at the beginning of September. Several areas are expected to bear the brunt of this unusual warmth:
- Southern Germany
- The Balkans
- Ukraine
- Baltic countries
These regions are likely to experience particularly high temperatures as the month begins.
Climate change continues to push the boundaries of seasonal norms, extending summer-like conditions well into September and even October across Europe. This prolonged warmth brings with it a host of potential challenges:
- Increased risk of extreme weather events
- Heightened threat of flooding
- More frequent violent storms
- Greater likelihood of wildfires
Despite these concerns, the milder weather could potentially delay the start of the heating season, echoing the pattern seen in 2023.
September holds significant importance for energy traders, as winter period contracts are typically negotiated at the month’s end. The rising demand for cooling systems has already impacted energy markets, with Italy witnessing record-breaking electricity prices in August. However, the true test for the broader region is expected to come with the arrival of winter.
Drought conditions are forecasted to persist in several areas throughout September, including:
- Much of the Iberian Peninsula
- The Balkans
- Eastern Europe
These ongoing dry spells are likely to exacerbate existing environmental and agricultural challenges in affected regions.
The outlook for the latter half of September remains uncertain, as it will be influenced by two major factors:
- The warm Atlantic Ocean
- An emerging La Niña phenomenon
Atlantic temperatures have been hovering near record highs for several months, historically correlating with warmer September temperatures across Europe. This trend could continue to impact weather patterns as autumn progresses.
Another potential wild card for September’s weather are the remnants of tropical systems. These could potentially affect the United Kingdom, France, and the Iberian Peninsula, bringing heavy rainfall and strong winds. Recent examples of this phenomenon include the aftermath of Hurricane Ernesto, which prompted yellow weather warnings in Scotland, and Storm Lilian’s movement across the Atlantic.
As Europe grapples with these unusual weather patterns, various sectors must prepare for potential impacts:
-
Energy:
- Increased demand for cooling systems
- Delayed start to the heating season
- Fluctuating energy prices
-
Agriculture:
- Extended growing seasons for some crops
- Drought-related challenges in affected regions
- Potential crop damage from extreme weather events
-
Tourism:
- Extended summer tourism season in some areas
- Potential disruptions due to extreme weather
-
Public Health:
- Heat-related health risks, especially for vulnerable populations
- Increased need for public cooling centres
- Potential air quality issues due to prolonged dry conditions
-
Infrastructure:
- Strain on power grids due to increased cooling demand
- Potential damage from storms or flooding
As Europe faces this unusually warm September, it’s crucial for governments, businesses, and individuals to remain adaptable and prepared for the various challenges that may arise. While the extended summer-like conditions may bring some benefits, the potential risks associated with extreme weather events and prolonged heat cannot be overlooked.
Monitoring systems and early warning protocols will play a vital role in mitigating potential hazards. Local authorities may need to implement measures such as:
- Water conservation initiatives
- Energy-saving programmes
- Public health campaigns focused on heat-related illnesses
The agricultural sector may need to adjust planting and harvesting schedules to accommodate the shifting seasons. Farmers might also need to explore more drought-resistant crops or improved irrigation techniques in areas prone to prolonged dry spells.
For the energy sector, the unusual weather patterns underscore the importance of diversifying energy sources and improving grid resilience. The potential for delayed heating seasons, coupled with increased cooling demands, may require a reassessment of traditional energy consumption models.
Tourism operators could capitalise on the extended warm weather by promoting autumn travel packages. However, they should also be prepared for potential disruptions caused by extreme weather events.
Urban planners and local governments may need to accelerate efforts to create more heat-resilient cities. This could include:
- Increasing green spaces
- Implementing cool roof technologies
- Improving urban water management systems
As Europe navigates this unseasonably warm September, the situation serves as a stark reminder of the ongoing impacts of climate change. While individual warm periods cannot be directly attributed to global warming, the increasing frequency and intensity of such events align with climate scientists’ predictions.
The continent’s experience this September may provide valuable insights into adapting to a warming world. It underscores the need for continued investment in climate research, sustainable technologies, and adaptive strategies to ensure Europe’s resilience in the face of changing weather patterns.
As autumn unfolds, all eyes will be on Europe’s weather systems, watching to see how this unusually warm start to September will influence the continent’s climate in the coming months. The situation serves as a microcosm of the broader climate challenges facing not just Europe, but the entire globe, as we grapple with the realities of a warming planet.
