December’s weather in detail

December marks the arrival of winter in South Korea and whilst temperatures are not yet as icy as can be expected in January and February they are much cooler than previous months. Temperatures in Seoul range from lows of 0°C to occasional highs of just 11°C. On the southern coast things remain more welcoming, with temperatures in the seaside city of Busan and on Jeju Island ranging from 10-16°C.   

Towards the end of the month snow can be expected, particularly in the northern provinces of Gyeonggi-do and Gangwon-do, home to the popular ski resorts of Pyeongchang. It will also feel cooler in the mountainous National Parks such as Songnisan.

You will definitely need to pack a few extra layers although if you're heading south you may still get some wear out of your t-shirts during the day.
