South Korea's four seasons
South Korea has a clearly defined four-season climate: cold, dry winters; warm, unpredictable springs; hot, humid, rainy summers; and crisp, mild autumns. The seasons shape not just weather but also what there is to see, from spring blossoms to autumn foliage.
Month-by-month overview
| Months | Season | What to expect |
|---|---|---|
| March–April | Spring | Mild days, cherry blossoms peak late March to early April |
| May | Late spring | Comfortable, dry, before summer humidity sets in |
| June–July | Monsoon (jangma) | Heavy, sustained rain across most of the country |
| August | Peak summer | Hot and humid, occasional typhoon risk |
| September–November | Autumn | Cool, dry, peak foliage mid-October to early November |
| December–February | Winter | Cold, dry, snow in mountain regions, ski season |
Best time for cherry blossoms
Bloom typically starts in the south around Busan and Jeju in mid-to-late March and reaches Seoul in early April. Bloom dates shift year to year with temperature, so check a current forecast a few weeks out rather than locking in dates too far ahead.
Best time for autumn foliage
Fall color moves from the northern mountains southward, generally peaking in Seoraksan National Park in early-to-mid October and reaching Seoul by late October to early November. This is one of the most popular times to visit, so book accommodation and domestic transport ahead.
Best time for lower prices
- January and February (outside Lunar New Year) are typically the cheapest months to fly, since winter draws fewer leisure travelers.
- Late June and July, despite the rain, also see lower fares and thinner crowds.
- Spring and autumn, being the most popular travel windows, carry the highest prices and require earlier booking.
Getting there
Most international flights land at Incheon International Airport (ICN) near Seoul, with Gimhae (Busan) and Jeju also serving international routes. Compare fares across these airports on a metasearch, and use a live flight tracker to monitor your inbound flight, especially during peak foliage or blossom season when airports get busy.
