Weather in Ushuaia Argentina in December Weather Pattern plays a significant role in defining the region’s climate, especially during the month of December. The weather in Ushuaia, Argentina, is largely influenced by the dominant high-pressure systems and their impact on temperature and precipitation patterns.
The Antarctic Circumpolar Current, a significant oceanographic feature, also influences the local weather in Ushuaia. In addition, the wind direction has a significant effect on temperature variations during December, resulting in significant fluctuations in temperature.
The average high and low temperatures in Ushuaia during December are usually around 11°C (52°F) and 8°C (46°F) respectively. However, the temperature can fluctuate throughout the day and night, depending on the wind direction and other weather conditions.
Weather Patterns in Ushuaia, Argentina in December
During December, Ushuaia, Argentina experiences a distinct weather pattern characterized by a dominant high-pressure system over the region. This system brings clear skies and moderate temperatures, typically ranging from 5°C to 10°C (41°F to 50°F). The prevailing wind direction during this time is from the southeast, resulting in a gentle breeze that contributes to the region’s pleasant climate.
Dominant High-Pressure Systems and Temperature Patterns
The high-pressure system that dominates Ushuaia in December has a significant impact on the region’s temperature and precipitation patterns. Characterized by clear skies and low humidity, this system allows for efficient heat transfer from the equator and prevents the formation of fronts or low-pressure systems. As a result, temperatures remain relatively stable, with average highs ranging from 9°C to 12°C (48°F to 54°F) and lows ranging from 2°C to 6°C (36°F to 43°F).
Role of the Antarctic Circumpolar Current in Influencing December Weather
The Antarctic Circumpolar Current (ACC) plays a crucial role in shaping the weather patterns in Ushuaia during December. As the world’s largest ocean current, the ACC circulates cold water from the Antarctic region and influences the temperature and precipitation patterns in the region. During December, the ACC brings a cold front that passes through Ushuaia, resulting in a moderate decrease in temperature. However, this front also contributes to the formation of orographic clouds, which can lead to precipitation in the region.
Effects of Wind Direction on Temperature Variations
The wind direction also plays a crucial role in temperature variations in Ushuaia during December. With the prevailing wind direction coming from the southeast, temperatures tend to remain stable and moderate. However, when the wind direction shifts to the west or northwest, temperatures can drop significantly, resulting in a cooling effect on the region. Conversely, when the wind direction shifts to the east or northeast, temperatures can rise, contributing to an increase in temperature in the region.

Precipitation Patterns in Ushuaia, Argentina in December
In the southernmost region of Argentina, Ushuaia is known for its significant precipitation patterns during December. As one of the wettest months, this period is characterized by frequent rain showers, which contribute to the overall water cycle of the Beagle Channel. The orographic effect of the Andes Mountains plays a crucial role in shaping the precipitation patterns in Ushuaia during December.
Main Sources of Precipitation
The main sources of precipitation in Ushuaia, Argentina during December are:
- The Southern Ocean: The cold and humid air masses from the Southern Ocean are a significant source of precipitation in Ushuaia. These air masses bring moisture from the ocean and contribute to the formation of low-pressure systems that produce rain showers.
- The Beagle Channel: The Beagle Channel, which separates the city from the mainland, also plays a crucial role in precipitation patterns. The channel acts as a conduit for warm, moist air from the Pacific Ocean, which leads to the formation of precipitation-bearing low-pressure systems.
- The Andes Mountains: The Andes Mountains, situated adjacent to Ushuaia, force warm, moist air to rise, resulting in orographic enhancement of precipitation. As the air is forced upwards, it cools, and the water vapor condenses, leading to rain showers.
Frequency and Duration of Rain Showers
During December, Ushuaia experiences frequent rain showers, with an average of 14 rainy days per month. The rain showers are often short-lived, lasting from a few hours to a full day. However, some prolonged periods of rainfall can occur, resulting in significant accumulations of precipitation.
Comparison with Other Months
Compared to other months in Ushuaia, December receives the most precipitation, accounting for approximately 18% of the annual total. The wettest month in the region is January, while the driest month is August.
Role of the Andes Mountains
The Andes Mountains have a profound impact on precipitation patterns in Ushuaia, Argentina. As moisture-laden air masses from the Southern Ocean and the Beagle Channel rise over the mountain range, they cool, and the water vapor condenses, resulting in orographic enhancement of precipitation. This process leads to the formation of precipitation-bearing low-pressure systems, which contribute significantly to the overall precipitation total in Ushuaia during December.
Orographic enhancement of precipitation occurs when air is forced to rise over a mountain range, resulting in cooling and condensation of water vapor, leading to increased precipitation.
Sunshine Hours and Cloud Cover in Ushuaia, Argentina in December
In the southernmost city of Argentina, Ushuaia, December is a significant month for sunshine hours and cloud cover patterns. Located on the Beagle Channel, Ushuaia experiences a subpolar oceanic climate, characterized by low temperatures, high humidity, and significant precipitation throughout the year.
Average Monthly Sunshine Hours in December
December is an interesting month for sunshine hours in Ushuaia, as it marks the beginning of the Southern Hemisphere’s summer. According to climate data, the average monthly sunshine hours in Ushuaia during December are approximately 4 hours and 30 minutes. This is relatively low compared to other months of the year, such as November and January, which receive around 6 hours of sunshine. The reduced sunshine hours in December are attributed to the city’s proximity to the Antarctic Circle, which casts a strong influence on the local climate.
Role of Cloud Cover in Controlling Temperature and Precipitation Patterns
Cloud cover plays a crucial role in controlling temperature and precipitation patterns in Ushuaia during December. The city is known for its high cloud cover, which ranges from 75% to 90% throughout the month. These thick clouds trap heat and moisture, resulting in a relatively uniform temperature of around 9°C (48°F) during the month. The cloud cover also contributes to precipitation patterns, with December being one of the wettest months in Ushuaia.
Typical Cloud Types in Ushuaia during December
The cloud types that dominate Ushuaia during December are mainly stratocumulus and altostratus clouds. These low-level clouds are characterized by a layered or rolled appearance and are composed of water droplets and ice crystals. Stratocumulus clouds are responsible for the majority of the precipitation in Ushuaia during December, while altostratus clouds contribute to the city’s overcast conditions.
Average Cloud Cover Percentages in Ushuaia during December
The average cloud cover percentages in Ushuaia during December are as follows:
– Low-level clouds (0-2 km): 50-60%
– Middle-level clouds (2-7 km): 25-35%
