Best Time to Visit South Korea: Weather, Seasons and Regions

Hey my friends! Congratulations on your upcoming trip to this wonderful country that we love so much. Choosing when to travel to South Korea is one of the first decisions you’ll have to make. The country has four very distinct seasons, and each one offers different landscapes, festivals and food. In this guide I’ll explain the best time to visit South Korea based on the weather and the region, so you can book with confidence and avoid surprises like the monsoon, the extreme cold or Seoul’s unbearable heat in the middle of July.

Everything You Need to Know Before Traveling to South Korea

Quick Answer: What Is the Best Time to Visit South Korea?

The best times to visit South Korea are April-May (spring) and September-October (fall). You’ll get pleasant temperatures, clearer skies and spectacular scenery: cherry blossoms in spring and red foliage in fall. If you prefer fewer crowds and lower prices, June and November are good alternatives.

South Korea Weather and What to Expect in Each Season

Spring (March-May): Cherry Blossoms and Mild Weather

It’s many travelers’ favorite season. Temperatures range roughly from 5 °C (41 °F) in early March to around 22 °C (72 °F) in May. Cherry blossoms usually open between late March and early April in the south, and reach Seoul in the first half of April. Dates vary every year, so check the bloom forecasts before booking your flight.

Pros: ideal weather, flower festivals, photogenic scenery. Cons: heavy tourism during peak bloom, higher prices, and episodes of fine dust (yellow dust) that can affect air quality.

Summer (June-August): Heat, Humidity and Rain

Summer is hot and humid, with temperatures frequently above 30 °C (86 °F). Between late June and July comes the changma (rainy season), with heavy downpours. In August and September, typhoons can appear, especially in the south and on Jeju.

Pros: lively beaches (Busan, Jeju), music festivals, hydrangeas in bloom in June and July, and cheaper accommodation on some dates. Cons: high humidity, rain, and possible flight cancellations due to typhoons.

If you decide to go in summer, I recommend avoiding Seoul and its surroundings. If you have no other option, get ready to sightsee early in the morning or in the evening… during the day the sun is unbearable.

Fall (September-November): The Golden Season

Many consider it the best time to go to South Korea. The weather is dry and mild, with highs of around 20-25 °C (68-77 °F) in September and about 12 °C (54 °F) in November. Fall foliage peaks in late October in the northern mountains and in late October or early November in Seoul.

Pros: clear skies, hiking, red and gold landscapes, food festivals. Cons: high demand in October and the Chuseok holiday (the harvest festival), when many Koreans travel and trains fill up.

Winter (December-February): Cold, Snow and Skiing

Winter is cold and dry, and temperatures in Seoul can drop below -10 °C (14 °F) on the harshest days. It’s the season for skiing and snowboarding in Gangwon, Christmas lights, and hot street food in the markets.

Pros: fewer tourists, low prices on flights and hotels, ski resorts, hot springs and jjimjilbang. Cons: intense cold, short days, and some businesses closing during Seollal (Lunar New Year).

Key Dates to Keep in Mind

Seollal (Lunar New Year) and Chuseok are family holidays. Many people travel around the country, trains and flights sell out, and some shops close. Check the calendar for each year, since the dates change, and book transportation well in advance if your trip overlaps with them.
