Chile Weather in March
Average Temperatures in March
Chile experiences a wide range of temperatures in March due to its unique geography. The country stretches along the western edge of South America, from the arid deserts in the north to the cold, southern ice fields. As March marks the beginning of autumn in the Southern Hemisphere, temperatures generally start to cool, but the conditions vary greatly depending on the region.
Highest and Lowest Temperatures
In Santiago, the capital of Chile, temperatures in March are relatively mild. During the day, average highs range between 23°C and 30°C (73°F to 86°F), with the occasional warmer day pushing temperatures into the 32°C (89.6°F) range. In the evenings, temperatures cool down to 11°C to 15°C (52°F to 59°F), making for pleasant nights. The days are generally sunny, and the heat from the afternoon can still be significant but is tempered by the cooler evening air.
In Valparaíso, a coastal city known for its mild climate, March sees slightly cooler temperatures. Average highs range from 20°C to 25°C (68°F to 77°F), while lows drop to around 12°C to 16°C (53.6°F to 60.8°F). The cool Pacific Ocean currents help keep the temperature in check, creating a more temperate environment.
Further south, in Patagonia and Punta Arenas, temperatures drop noticeably in March. Daytime highs typically range from 10°C to 15°C (50°F to 59°F), while nighttime lows can dip to 2°C to 5°C (35.6°F to 41°F). It is important to note that the further south you go in Chile, the more unpredictable the weather becomes, with the likelihood of cold winds and even early snow at higher altitudes.
In the Atacama Desert, the northernmost region, temperatures remain relatively warm in March. Average highs can reach 26°C to 30°C (78°F to 86°F), with cooler nights that can drop to 10°C to 14°C (50°F to 57°F).

This table reveals the consistent pattern of temperatures, with Santiago seeing higher temperatures than Valparaíso or Punta Arenas. Santiago and Valparaíso are much warmer than Patagonia, which cools down significantly by March.
Precipitation Levels
In March, precipitation levels in Chile vary dramatically depending on the region. The central region, including Santiago and Valparaíso, sees relatively low precipitation in comparison to the southern regions of the country.
Rainfall Patterns
In Santiago, March is typically a dry month, with precipitation averages ranging from 10mm to 20mm. Rainfall tends to increase slightly towards the end of the month, marking the transition into the wetter season of autumn. While rain showers are relatively infrequent, the change in weather patterns means that occasional showers can be expected, particularly towards the south.
In Valparaíso, the coastal climate also experiences moderate rainfall, averaging 10mm to 15mm of precipitation in March. The rains are light to moderate and usually occur in short bursts, so they don’t significantly impact daily activities. The higher humidity from the ocean also contributes to occasional drizzly conditions.
The Atacama Desert remains extremely dry, with virtually no rainfall in March. This region is known as one of the driest places on Earth, and March does not deviate from this pattern, with less than 1mm of rain recorded.
In Patagonia, precipitation levels are higher. Cities like Punta Arenas receive 20mm to 30mm of rain during March, signaling the arrival of cooler, wetter weather as the season transitions. The weather in this region can be unpredictable, and rain can be heavier in the mountains and coastal areas.
Snowfall
In the mountainous regions of Patagonia, snowfall is still possible in March, although less frequent than in the earlier winter months. The Andes Mountains can receive snow at higher elevations, but it is typically light. In lower areas, such as Punta Arenas, snow is rare in March, with the focus shifting more towards rain.
Wind Patterns
March in Chile sees variable wind patterns, with the southern regions experiencing stronger winds than the north.
Winds in the North
In the Atacama Desert and northern Chile, wind speeds remain relatively calm. The winds here are typically light, with occasional gusts from the east or northeast. In desert areas, the winds are dry and can carry fine sand across the landscape, but they are not generally disruptive to travel.
Winds in the Central and Southern Regions
As you move further south, the wind picks up. Valparaíso and Santiago experience moderate winds, ranging from 10 km/h to 20 km/h (6 mph to 12 mph). Wind speeds can occasionally increase during a passing weather front, but strong winds are not frequent in the central region during March.
In Patagonia, particularly in Punta Arenas, wind speeds are significantly stronger. Winds can reach 30 km/h to 50 km/h (18.6 mph to 31 mph), often accompanied by gusts. These winds, combined with the cooler temperatures, can make it feel much colder than the actual air temperature, particularly in the open landscapes.
Atmospheric Pressure
Atmospheric pressure in March tends to follow the transition from the dry summer months to the wetter autumn period, leading to fluctuations as low-pressure systems move across the country. The weather can become more variable, with pressure systems that contribute to cooler conditions and occasional rainfall.
Low-Pressure Systems
In the central and southern regions, particularly around Santiago and Valparaíso, low-pressure systems can lead to rainfall, especially towards the end of the month. These systems are typically not severe but can create conditions conducive to light rain and stronger winds.
Considerations for Travelers in Chile During March
March offers a diverse range of experiences for travelers in Chile, but there are several important considerations to ensure a comfortable and enjoyable trip.
Packing Essentials for March
Given the wide range of climates in Chile, it’s essential to pack layers for your trip. In the central and northern regions, lighter clothing such as t-shirts, long sleeves, and a light jacket will suffice for the daytime. For evenings, especially in Santiago, a medium-weight jacket will keep you comfortable.
If you’re traveling to the Patagonian region or higher altitudes in the Andes, you should prepare for cooler temperatures and possibly rain or snow, even in March. Bring a warm jacket, rain gear, and sturdy waterproof footwear. A hat and gloves are recommended if you plan to visit the mountains, as winds can be chilly.
In the Atacama Desert, the weather can be warm during the day, but nights can get very cold. Be prepared with layers for temperature swings.
Health and Safety Considerations
While Chile is known for being a relatively safe destination, travelers should still take precautions. In southern areas, such as Patagonia, where temperatures can fluctuate dramatically, travelers should be aware of the potential for altitude sickness. It is recommended to take it easy when arriving in higher regions and allow your body to acclimatize.
In desert regions, such as the Atacama, be mindful of dehydration due to the dry air. Drink plenty of water and protect your skin from the harsh sun.
Travel Disruptions Due to Weather
In March, rainstorms can occasionally affect travel, particularly in Patagonia. Strong winds can delay flights or ferry services, particularly around Punta Arenas and the southern fjords. Travelers should always check weather conditions before heading out, especially when traveling to more remote areas.
Currency and Economic Considerations
Chile uses the Chilean Peso (CLP), and major credit cards are widely accepted in urban areas like Santiago and Valparaíso. However, if traveling to more remote areas, especially in the north or south, it is advisable to carry some cash, as smaller shops and markets may not accept cards.
Things to Do in Chile in March
March is a wonderful time to explore Chile, as the summer crowds begin to thin, and the weather is still favorable in many parts of the country.
Outdoor Activities in Patagonia
For adventure lovers, March is a great time to visit Patagonia. The cooler weather makes it ideal for hiking in Torres del Paine National Park, known for its stunning landscapes and challenging trails. The winds can be strong, but the lack of summer crowds means a more peaceful experience.
Wine Tours in the Central Valley
March is harvest season for Chile’s famous wines, and a visit to the Central Valley offers the chance to participate in wine tours and tasting events. The Maipo Valley, Colchagua Valley, and Rapel Valley are famous wine regions, and March is one of the best times to visit for a wine-tasting experience.
