Understanding the Climate of Greece in December: Greece Weather In Dec

December is a transitional month in the Greek climate, marking the end of autumn and the beginning of winter. While temperatures range from cool to mild, depending on the region, the Mediterranean Sea’s influence plays a significant role in shaping the weather patterns.
The Role of the Mediterranean Sea in December Weather Patterns
The Mediterranean Sea has a moderating effect on Greece’s climate, keeping temperatures relatively mild during December. The sea’s warmth radiates heat onto the land, preventing extreme temperature fluctuations. However, this influence can also lead to unpredictable weather patterns, with cold fronts and warm air masses interacting to produce varying conditions.
Temperature Variations Across Greece in December
Temperature averages vary significantly across different regions in Greece during December. Here are some examples of temperature averages in 5 major cities:
- Temperature averages in December are relatively mild in the southern cities, while the northern cities experience cooler temperatures. For instance, Athens, the capital city, has average high temperatures ranging from 12°C to 14°C (54°F to 57°F), while Thessaloniki, in the north, has average high temperatures around 8°C to 10°C (46°F to 50°F).
- Regions closer to the sea tend to be warmer than those inland. Heraklion, on the island of Crete, has average high temperatures around 15°C to 17°C (59°F to 63°F), while Patras, in the north, has average high temperatures around 10°C to 12°C (50°F to 54°F).
- The island of Mykonos, known for its mild winters, has average high temperatures around 12°C to 14°C (54°F to 57°F), while the nearby island of Santorini has average high temperatures around 10°C to 12°C (50°F to 54°F).

Greece Weather in December – A Regional Breakdown

Greece’s diverse geography gives rise to varied weather conditions across different regions in December. The country’s landscape is characterized by mountains, islands, and coastlines, each with its unique climate.
The Aegean Islands’ Climate in December
The Aegean Islands, including popular destinations like Mykonos and Santorini, experience a Mediterranean climate in December. The island size plays a significant role in shaping their climate, with larger islands generally being colder and windier than smaller ones. For instance, the wind direction and speed on larger islands can be influenced by the prevailing westerly winds, resulting in cooler temperatures. On the other hand, smaller islands often have more moderate temperatures, thanks to their limited exposure to wind and the surrounding sea. The sea temperatures in the Aegean are significantly cooler during December, with average temperatures ranging from 13°C to 16°C (56°F to 61°F).
| Island | Average Temperature (°C) |
|---|---|
| Mykonos | 12°C (54°F) |
| Santorini | 13°C (56°F) |
| Cyclades (average) | 14°C (57°F) |
The Peloponnese Peninsula’s Distinct Weather Patterns
The Peloponnese Peninsula is characterized by a diverse landscape, ranging from sea coasts to mountains. This diversity gives rise to distinct weather patterns, particularly noticeable in the regions surrounding the Messenian Gulf. The sea and land temperature fluctuations significantly impact the climate in these areas. During December, the average temperature in coastal areas is around 12°C to 14°C (54°F to 57°F), while the mountainous regions, such as the Taygetus range, experience significantly colder temperatures, often below 8°C (46°F). The unique combination of land and sea temperatures creates a variety of microclimates within the peninsula, with areas closer to the coast experiencing milder winters than higher elevation areas.
Mountainous Regions vs. Coastal Areas
Mountainous regions in Greece, such as Olympus and Parnon, exhibit different weather patterns compared to coastal areas. These regions receive more precipitation and experience colder temperatures, especially during December. The mountainous areas often witness snowfall, which can be quite significant in higher elevations. In contrast, coastal areas experience more moderate temperatures and precipitation patterns, with a greater influence from the Mediterranean Sea. The following table presents temperature data for different elevations in the mountainous regions of Greece:
| Elevation (meters) | Average Temperature (°C) |
|---|---|
| 500 meters (1,640 ft) | 6°C (43°F) |
| 1,000 meters (3,300 ft) | 3°C (37°F) |
| 2,000 meters (6,600 ft) | 0°C (32°F) |

Weather Extremes in December – Greece
Greece experiences a range of extreme weather events in December, including intense storms and heatwaves. These events can have significant impacts on the country’s infrastructure, agriculture, and overall economy. In this section, we will explore some of the most notable extreme weather events that have occurred in Greece during December.
Historical Weather Records in Greece
Greece has a rich history of extreme weather events, with many instances of temperature and precipitation patterns being more extreme than usual. According to the National Observatory of Athens, some of the most notable historical weather records in Greece include:
- The intense storm of 2005, which brought heavy rain and strong winds to the entire country, causing widespread power outages and property damage. The storm was so severe that it was dubbed the “Storm of the Century” by the Greek media.
- The heatwave of 1988, which brought record-breaking temperatures to many parts of the country, including the island of Crete, where the temperature reached a scorching 46°C (115°F) in July. This heatwave was so severe that it led to a state of emergency being declared in many areas.
- The cold snap of 2010, which brought temperatures below -10°C (14°F) in some parts of the country, causing widespread power outages and property damage. The cold snap was so severe that it led to a significant increase in the number of deaths related to hypothermia.
Global Climate Trends and Local Topography
The extreme weather events that occur in Greece in December can be attributed to a combination of global climate trends and local topography. The warming of the Mediterranean Sea, which borders Greece, has led to an increase in temperatures and a shift in precipitation patterns. This, in turn, has contributed to the occurrence of more intense storms and heatwaves in the region.
The complex topography of Greece, which includes mountains, valleys, and coastal regions, also plays a significant role in the country’s weather patterns. The country’s mountain ranges, such as the Pindus Mountains, can force moist air to rise, cool, and condense, resulting in precipitation. In contrast, the coastal regions, such as the Peloponnese, are more exposed to storms and heatwaves from the Mediterranean Sea.
