Yearly Average

Throughout the year, Coquimbo’s average temperature remains relatively mild. The city’s annual mean temperature is approximately 14°C. This temperature is influenced by both the Pacific Ocean, which helps regulate extremes, and the surrounding desert landscape, which contributes to warm daytime temperatures and cooler nights. In general, Coquimbo’s climate is characterized by its low humidity, making even hot summer days feel comfortable and breezy.

Coastal Clouds

Coquimbo’s coastal location profoundly influences its cloud formations. The collision of the cold Humboldt Current with the warm coastal air creates a temperature gradient that nourishes low-lying clouds. These clouds, known as stratus and stratocumulus, form a persistent blanket over the coastal area, often obscuring the sun and creating a misty atmosphere. The presence of coastal fog, particularly during the morning hours, further adds to the cloud cover, creating a unique and often-spectacular weather pattern.

Orographic Clouds

The topography of the Coastal Range contributes to the formation of orographic clouds. As moist air from the Pacific Ocean ascends the western slopes of the mountains, it cools and condenses, giving rise to thick layers of clouds. These clouds stretch along the mountain range and contribute significantly to the region’s precipitation. The most common types of orographic clouds in Coquimbo are cumulus and cumulonimbus clouds, which can lead to showers and thunderstorms, particularly during the summer months.

Annual Precipitation Patterns

Coquimbo, Chile, experiences a distinct precipitation pattern, characterized by aridity throughout the year. The region lies within the Atacama Desert, one of the driest deserts on Earth. Annual precipitation averages a mere 10 mm (0.4 inches). The driest months are between October and March, when virtually no rain falls. The wettest months occur from May to August, although precipitation remains sporadic and often limited to light showers.

Influence of the Atacama Desert

The location of Coquimbo within the Atacama Desert plays a significant role in its low precipitation. The desert’s coastal mountains block moisture-bearing clouds from reaching the region. Additionally, the cold Humboldt Current offshore cools the air and reduces evaporation, further contributing to the aridity. The combination of these factors results in an extremely dry climate that has shaped the region’s landscape and ecosystem.

Rainfall Patterns in Coquimbo, Chile

Coquimbo, a region in northern Chile, is characterized by a dry climate with minimal rainfall throughout the year. The average annual precipitation in the region is less than 100 mm, concentrated primarily during the winter months (May to September). Rainfall is highly variable from year to year, with some years receiving significantly more rainfall than others.

The Atacama Desert, which borders Coquimbo to the north, acts as a natural barrier to moisture from the Pacific Ocean. The cold Humboldt Current flowing along the coast also contributes to the desert-like conditions by inhibiting the formation of clouds and precipitation. However, occasional rainfall events can occur during winter, typically caused by the passage of cold fronts or atmospheric disturbances from the south.

History of Snowfall in Coquimbo, Chile

Snowfall in Coquimbo, Chile, is a rare occurrence. The region is located in the northern part of the country, where the climate is typically arid and subtropical. However, on rare occasions, cold fronts from the south can bring snowfall to the region. The most recent snowfall in Coquimbo occurred in 2021, when several inches of snow fell in the city of La Serena. This was the first time that snowfall had been recorded in the city in over a decade.

Causes of Snowfall in Coquimbo, Chile

The primary cause of snowfall in Coquimbo, Chile, is the arrival of cold fronts from the south. These fronts can bring cold air and precipitation to the region, which can lead to snowfall. In addition, the presence of the Andes Mountains to the east of Coquimbo can also contribute to snowfall. The mountains can block warm air from reaching the region, which can lead to colder temperatures and snowfall.

Impacts of Snowfall in Coquimbo, Chile

Snowfall in Coquimbo, Chile, can have a significant impact on the region. The weight of the snow can damage buildings and infrastructure, and it can also make travel difficult. In addition, the cold temperatures can lead to hypothermia and other health problems. However, snowfall can also have a positive impact on the region. The snow can provide water for crops and livestock, and it can also attract tourists to the area.

Sunrise and Sunset Times in Coquimbo, Chile

Coquimbo, Chile, experiences a range of sunrise and sunset times throughout the year due to its location in the Southern Hemisphere. The longest day of the year falls around December 21st, when the sun rises at approximately 6:00 AM and sets around 9:00 PM. Conversely, the shortest day of the year occurs around June 21st, with sunrise occurring around 8:00 AM and sunset taking place around 5:30 PM.

Sun Intensity and UV Index in Coquimbo, Chile

During the summer months (November to March), the sun is particularly intense, with UV index levels reaching 10 or higher. It is important to take precautions to protect yourself from the sun’s harmful rays, such as wearing sunscreen, sunglasses, and protective clothing. In the winter months (June to August), the sun is less intense, with UV index levels typically below 5.

Seasonal Variations

Coquimbo, Chile, experiences significant seasonal variations in humidity levels. During the summer months (December to March), the humidity is generally low, with average relative humidity values ranging from 60% to 80%. This low humidity is due to the influence of the cold Humboldt Current, which brings cool, dry air from Antarctica. The lack of rainfall and the strong coastal breeze further contribute to the low humidity.

Geographic Factors

The humidity in Coquimbo is also influenced by its proximity to the ocean and its topography. The coastal region, including Coquimbo, is exposed to the moisture-laden air from the Pacific Ocean, which can lead to higher humidity levels. However, the city is also surrounded by hills and mountains, which block some of the moisture from reaching the city center. As a result, humidity levels in Coquimbo tend to be higher along the coast and lower inland.

Influence of Topography on Wind Patterns

Coquimbo’s unique coastal topography significantly influences its wind patterns. The Andes Mountains, rising to the east of the city, create a rain shadow effect that reduces precipitation and results in predominantly dry conditions. This, in turn, creates strong, consistent winds that blow predominantly from the south-southeast. The passage of these winds through the narrow valley between the mountains and the ocean intensifies their speed, resulting in near-constant high winds in Coquimbo.

Impact of Wind on Daily Life and Industry

The persistent wind in Coquimbo has a profound impact on daily life and local industry. For outdoor activities, it can be invigorating or challenging, depending on personal preference and the specific activity. The wind also provides a natural advantage for wind energy production, making Coquimbo a hub for renewable energy. The city has numerous wind farms harnessing the abundant wind energy, contributing significantly to its electricity generation and reducing its reliance on fossil fuels. Additionally, the wind has spurred the development of windsurfing and kitesurfing as popular recreational activities in the region.
