December Weather Patterns in the Andes Mountain Range
The Andes mountain range, stretching through seven countries in South America, is known for its dynamic and varied climate. During December, the Andes experience a transition from autumn to winter, with a noticeable decrease in temperature and an increase in precipitation.
Typical Weather Conditions in December
In the Andes, December typically brings cool temperatures, with average highs ranging from 5°C to 10°C (41°F to 50°F) and average lows between 0°C and 5°C (32°F and 41°F) in the mountainous regions. Precipitation is also common, with most areas receiving around 100-150 mm (4-6 in) of rainfall throughout the month. However, snowfall in the higher elevations is a common occurrence, with some regions receiving significant snowfall.
Climate Change and Snowfall Patterns
Climate change has a noticeable impact on the Andes mountain range, particularly in terms of snowfall patterns. Warmer temperatures and changes in precipitation patterns have led to a decline in snowfall in some areas, resulting in shorter ski seasons and altering traditional snow-dependent activities such as agriculture. For example, a study published in 2020 showed that the length of the ski season in the Andes has decreased by up to 20 days in the past three decades.
Notable Events and Festivals in December
December is a festive month in the Andes, with many traditional celebrations taking place. Some notable events and festivals include the Festival de la Navidad in Chile, a festive celebration of Christmas that takes place in the city of Santiago, and the Inti Raymi in Peru, a reenactment of the Inca Festival of the Sun that takes place on June 24, but has a spin-off in late November with a similar festive atmosphere.

Regional Variations in December Weather
Chile’s diverse geography and climate make it a country with unique regional variations in December weather. From the driest desert in the north to the lush rainforests in the south, Chile’s varied landscape creates distinct weather patterns throughout the country. For instance, in the north, December is characterized as a dry and sunny month, while in the south, the region experiences high precipitation and overcast skies.
Regional Climate Patterns
Chile’s north, including the Arica and Parinacota, Antofagasta, and Atacama Regions, experiences a hyperarid climate, with very little rainfall throughout the year. In December, this region experiences an average high temperature of around 18°C (64°F), making it an ideal destination for those seeking a warm and sunny escape. However, as one moves south, the climate becomes increasingly humid and rainy. The Santiago Metropolitan Region and the surrounding areas experience a Mediterranean climate, with December temperatures ranging from 20°C (68°F) to 7°C (45°F). In contrast, the south of Chile, including the Los Lagos and Aysén Regions, experiences a temperate rainforest climate, with significant rainfall throughout the year. In December, these regions receive an average of 100-120 mm (3.9-4.7 in) of rainfall, making it an ideal time for exploring the region’s lush forests and scenic coastlines.
Effects of Climate on Local Culture and Lifestyle
The regional variations in climate also influence the local culture and lifestyle of Chileans. For example, in the north, where the dry climate dominates, outdoor activities such as hiking, biking, and surfing are popular pastimes during December. In contrast, in the south, where the rainy climate prevails, Chileans tend to spend more time indoors, enjoying traditional cuisine and local arts and crafts. In the Santiago Metropolitan Region, the mild climate allows for a wide range of outdoor activities, from hiking and biking to skiing and snowboarding.
“In December, the sky in Santiago is as clear as a mirror, but in the south, the rain comes down like a waterfall.”

Overall, Chile’s diverse climate and geography make it a country with a rich cultural and geographical heritage, offering unique experiences for visitors and residents alike.
Climate Change Impacts on December Weather in Chile
Climate change is having a significant impact on December weather in Chile, leading to more frequent and severe extreme weather events. Rising global temperatures are altering the distribution of precipitation and temperature patterns in the country, resulting in more frequent droughts and floods. Understanding these changes is crucial for mitigating their effects and adapting to the changing climate.
Duration and Severity of Extreme Weather Events
Climate change is leading to more prolonged and intense heatwaves, droughts, and floods in Chile during December. This is due to the melting of polar ice caps and the resulting rise in global temperatures, which is causing changes in atmospheric circulation patterns. As a result, the country is experiencing more frequent and severe heatwaves, leading to increased risk of wildfires and water scarcity.
According to a study published in the Journal of Climate, the duration and severity of heatwaves in Chile have increased by 20% and 30%, respectively, over the past three decades. This is particularly concerning for the rural population, who rely on rain-fed agriculture for their livelihood.
Role of Global Climate Patterns
Global climate patterns, such as the El Niño-Southern Oscillation (ENSO) and the Southern Annular Mode (SAM), play a crucial role in shaping December weather in Chile. These patterns influence the distribution of atmospheric circulation, temperature, and precipitation over the country. Understanding these patterns is essential for predicting December weather in Chile.
ENSO, for example, affects the distribution of precipitation in Chile, with El Niño events leading to droughts and La Niña events resulting in floods. SAM, on the other hand, influences the position and strength of the South Pacific High, which in turn affects the temperature and precipitation patterns over the country.
Projected Climate Changes in Chile and Other Countries
Here is a comparison of the projected climate changes in Chile with other countries in South America:
| Country | Temperature Change (°C) | Precipitation Change (%) |
| — | — | — |
| Chile | 2-4°C by 2050 | 10-20% decrease in annual rainfall |
| Argentina | 2-3°C by 2050 | 5-10% increase in annual rainfall |
| Peru | 2-3°C by 2050 | 5-10% decrease in annual rainfall |
| Bolivia | 2-3°C by 2050 | 10-20% increase in annual rainfall |
Note: The temperature and precipitation changes are based on the Coupled Model Intercomparison Project (CMIP5) scenarios.
