Average Temperatures in March
In South Korea, March marks the transition from winter to spring, which is reflected in the country’s gradually warming temperatures. While the weather begins to improve, it can still feel quite cold, especially early in the month. Southern regions, such as Busan, experience milder conditions compared to the northern regions, including Seoul, where temperatures remain cooler. Snow is still a possibility in some areas, particularly in the mountains, but rainfall is typically sparse during this time.
Highest and Lowest Temperatures
In Seoul, the capital located in the northern part of the country, March sees daytime highs averaging between 5°C and 10°C (41°F to 50°F), with lows at night dropping to -2°C to 2°C (28°F to 35.6°F). Early March can still feel like winter, especially at night, but by the end of the month, the temperatures begin to rise, and the days become noticeably longer.
In Busan, located along the southern coast, March is milder compared to the northern regions. Daytime highs range from 9°C to 14°C (48.2°F to 57.2°F), with lows in the evening between 2°C and 6°C (35.6°F to 42.8°F). The coastal location of Busan helps to moderate the temperatures, making it more pleasant compared to inland areas.

Precipitation Levels
March is a transition month in South Korea, where the country is moving from the dry winter period into the wetter spring season. While rainfall is still relatively low in March compared to the peak monsoon months (June to August), it is common for short, intermittent showers or thunderstorms to occur, particularly in the latter part of the month.
Rainfall Patterns
In Seoul, March sees moderate rainfall with precipitation averaging around 40mm to 60mm. These rain showers are typically scattered and brief, and the weather is still mostly dry for the first half of the month. By the end of March, rainfall tends to increase, signaling the arrival of spring.
Busan and the coastal areas generally experience lighter rain, with total precipitation ranging from 35mm to 50mm. Rain is generally less frequent here, but the coastal regions are still prone to occasional downpours.
In Jeju, which has a milder, subtropical climate, March brings slightly more rain than the mainland, with precipitation averaging between 40mm to 50mm. Although rain is more common in the latter part of the month, the region still experiences sunny spells in between showers.
In the northern and mountainous regions like Pyeongchang, March is still quite dry, though occasional snowfall can occur. Snowfall in this area can still add up to 10mm to 15mm of precipitation, particularly in the higher altitudes of the Gangwon Province.
Snowfall
March is still part of the winter season in the mountains, and snowfall is possible, particularly in the Gangwon region. Areas like Pyeongchang and Gangneung receive more snow in March than other parts of South Korea, as they are at higher altitudes. Snowfall can still accumulate during the early part of the month, especially if cold fronts move in.
However, snowfall becomes much rarer in Seoul and Busan in March. Snow is occasionally possible in these areas, but it typically melts quickly, and the conditions are not conducive for long-lasting snow.
Wind Patterns
In March, South Korea experiences moderate winds, with coastal areas generally receiving more wind than inland regions. The country’s proximity to the East Sea and the Yellow Sea results in occasional gusty winds, particularly along the coast and in the mountains.
Coastal Winds
In Busan and Jeju, the winds are typically moderate, with speeds averaging from 20 km/h to 35 km/h (12 mph to 22 mph). Winds are generally stronger in the afternoons, and occasional gusts can make the weather feel colder, especially near the coast.
Inland Winds
In Seoul and Incheon, wind speeds are generally lighter but still noticeable. Winds tend to range from 15 km/h to 25 km/h (9 mph to 15.5 mph), and although they are not as strong as in coastal areas, they can still add a chill to the air, particularly in the mornings and evenings.
Mountain Winds
The Gangwon Province region, which is located in the northeastern part of the country, experiences the strongest winds, especially in higher elevations. These winds can reach 40 km/h to 50 km/h (24.8 mph to 31 mph) and can create more extreme conditions, particularly when combined with snowstorms or low temperatures.
Atmospheric Pressure
In March, South Korea experiences fluctuating atmospheric pressure due to the transition from winter to spring. During this time, low-pressure systems associated with rain and snow can affect the country, particularly in the central and northern regions. These pressure systems bring occasional weather fronts that result in rain or snow.
Low-Pressure Systems
The transition from the dry winter season to the wetter spring months leads to low-pressure systems moving across the country. These systems bring rain and cloud cover, and may cause brief disruptions in outdoor activities, especially in Seoul and Gangwon. The latter part of March can often see an increase in these systems, with more frequent rain.
Considerations for Travelers in South Korea During March
Traveling to South Korea in March offers the advantage of mild spring weather, though there are still a few cold days and occasional precipitation. Here are a few factors to consider:
Packing Essentials for March
Since temperatures can vary widely depending on the region, it’s important to pack layers when traveling to South Korea in March. For cities like Seoul and Busan, pack light sweaters, jackets, and comfortable shoes for walking. Scarves and gloves are useful for the colder evenings, especially in Seoul and the mountains.
In Jeju and Busan, bring lighter clothing for the daytime, but also pack a light jacket or sweater for the evenings. It’s advisable to bring waterproof clothing, as rain showers can occur throughout the month.
If you plan to visit the Gangwon region for outdoor activities like skiing or snowboarding, pack winter gear, including thermal layers, gloves, and a snow jacket. While March is the tail end of the winter sports season, the Alps-like conditions in the mountains make it a good time for skiing.
Health and Safety Considerations
South Korea is a very safe destination for tourists, but as with any travel, it’s important to stay hydrated and protect yourself from the sun during the day. While March is not the peak tourist season, it’s always a good idea to have travel insurance that covers unexpected weather-related disruptions or medical issues.
Travelers should also be aware of the air quality in some urban areas like Seoul, particularly during the spring months when yellow dust from China can affect air quality. It’s advisable to check air quality forecasts and wear a mask if you are sensitive to particulate matter.
Travel Disruptions Due to Weather
While March is generally a good month to visit South Korea, travelers should be aware of possible weather disruptions due to rain or snow. Snowstorms can occasionally cause flight delays, especially in northern regions or Gangwon Province. Similarly, strong winds can affect mountainous areas, making outdoor activities more challenging.
Travelers should check weather forecasts regularly, especially if visiting remote areas or planning outdoor activities such as hiking or skiing in Gangwon Province.
Currency and Economic Considerations
The official currency in South Korea is the South Korean Won (KRW), and credit cards are widely accepted in larger cities like Seoul and Busan. ATMs are widely available, but it is a good idea to have some cash for smaller towns or when visiting rural areas. Currency exchange can be done easily at airports or local banks.
Things to Do in South Korea in March
March is an ideal time to explore South Korea due to the pleasant weather and fewer crowds compared to peak tourist seasons. Here are some things you can do:
Cherry Blossom Viewing
One of the most iconic experiences in South Korea in March is cherry blossom viewing. By the end of the month, cherry blossoms start to bloom in Seoul, Busan, and Jeju Island, making it the perfect time for a scenic walk in Namsan Park, Yeouido, and Jinhae. The cherry blossom festivals are held in various cities, offering cultural events and stunning photo opportunities.
Skiing and Snowboarding
For winter sports enthusiasts, March is still a good time to visit Gangwon Province, home to some of the best ski resorts in South Korea, such as Yongpyong and Alpensia. March offers milder conditions, so it’s a great time to enjoy the slopes with fewer crowds.
Hiking in the Mountains
South Korea is known for its rugged mountains, and March is an excellent time for hiking. You can explore popular trails in Seoraksan National Park, Bukhansan, and Jirisan. The spring weather, while still cool in the early part of the month, offers comfortable hiking conditions as the snow melts in the lower altitudes.
Visit Historical Sites
South Korea has a wealth of historical sites, including Gyeongbokgung Palace, Changdeokgung Palace, and the Demilitarized Zone (DMZ). March, with its milder temperatures, is a great time to explore these sites without the heavy crowds that fill up during the summer.
Cultural Festivals
In addition to the cherry blossom festivals, South Korea also celebrates various cultural events in March. The Seoul Kimchi Making & Sharing Festival is one such event where you can experience Korean cuisine and learn about kimchi-making, a staple of Korean food culture.
South Korea in March offers a wide range of experiences, from cultural festivals to outdoor activities, making it an excellent time to visit the country.
