August's weather in detail

As the South Korean summer heat and humidity continues into August, this is a time to seek out air-conditioned spaces in Seoul, the lofty mountains of Seoraksan National Park, and southern coastal resorts, such as Busan and Jeju Island, that offer a refreshing breeze.

Monsoon rains can be expected throughout the country, providing South Korea with more than half of its annual rainfall during the months of July and August. There is also a limited risk of typhoons, although these mainly affect neighbouring countries, with South Korea sheltered by the land masses of China and Japan. A couple of typhoons reach South Korea each year and, although these have not caused major problems in recent years, there is the possibility of landslides in hilly areas and a few extremely wet days as they wend their way across the country.

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.
