Weather in Seoul

Best time to visit

Seoul has a temperate climate and is a city with four distinct seasons, giving you a unique experience whenever you choose to visit.

Spring (March – May) is the best time to visit Seoul as the weather is pleasant and you can witness the annual Jongmyo Daeje ritual, an ancestral rite that incorporates Korean court music and dance, on the first Sunday of May.

Summer (June – August) sees the arrival of monsoon rains, leaving the city hot and humid. Temperatures hover in the high-twenties and the most rain falls in July.

Autumn (September – November) is an ideal time to visit Seoul as temperatures are in the comfortable 12°C (54°F) to 26°C (79°F) range. The city is awash with colour as leaves on the trees turn red, yellow and orange – providing the perfect backdrop for your holiday snaps.

Winter (December – February) can be very cold, with temperatures often reaching minus figures. Spend time at a mogyoktang, or Korean bathhouse, to keep warm and to feel like a Seoul local.
