Quick Picks – The Best Times to Visit Korea at a Glance

Best Budget-Friendly Season
Late November to March is the low season. During these months, flight and hotel prices are typically 20–40% lower than peak times. This period sees the fewest tourists, making it ideal for budget-conscious travelers seeking deals and quieter attractions.
Best Time for Festivals and Local Events
Spring and autumn host the bulk of Korea’s signature festivals. Don’t miss Jinhae’s Cherry Blossom Festival (early April; over 1 million visitors) and the Busan Fireworks Festival (early October). The Lotus Lantern Festival in May and Seoul Lantern Festival in November are also highlights.

Spring (March–May) is perfect for hiking and park strolls among blooming flowers, while autumn (September–November) is prime for mountain trails and national parks enveloped in red-orange foliage. These shoulder seasons have lower humidity and less rainfall compared to summer.
Factors Influencing the Best Time to Travel to Korea
Weather and Climate Changes (2026 Update)
Recent data (2020–2025 averages, 2026 forecasts) indicates average temperatures in South Korea are gradually rising. Winters are milder (+0.5–1°C compared to 2010), and springs arrive earlier. Climate models predict cherry blossoms and fall foliage peaking 7–15 days earlier than in previous decades. Rainfall is heaviest in July and August (300–400mm/month in Seoul).
Crowds, Holidays & Local Events
Major Korean holidays—Lunar New Year (January–February) and Chuseok (September–October)—see surges in domestic and international travel. Booking early during these periods is crucial, especially for Seoul and Busan, which saw a 30% year-on-year rise in Chinese arrivals in 2026. Festivals like cherry blossom and autumn foliage also drive up visitor numbers; popular urban spaces and nature spots can be crowded, with up to 2–3× more visitors at key sites.
