May’s weather in detail

You can expect pleasant weather throughout South Korea during May. Average temperatures are comfortable rather than sticky and muggy and the summer rains are yet to arrive, making conditions especially good for trekking in the National Parks of Jirisan, Songnisan and Seoraksan. Days are typically sunny, dry and warm, particularly in the southern city of Busan and on Jeju Island.

The capital, Seoul, offers a fairly typical indication of what the thermometers will read in South Korea during May, with average minimum temperatures of 8°C and the possibility of positively balmy highs of 17°C.
