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.

Our recommended journeys

Besides close geographical proximity South Korea and Japan share many similarities and make natural holiday partners. Both are countries rich in ancient history, where deep-rooted traditions are balanced by contemporary culture and technological sophistication. Natural wonders and scenic beauty can be found throughout the two, as can a distinctive cuisine and friendly people. This ten day itinerary offers a teasing taster of both destinations.
