What's the tourist weather like in Jeju Island in mid-August? What's the consumption like in Jeju Island?

The weather is similar to that in Shandong and other places, so it is necessary to prepare equipment for sun protection, rain protection and cooling. South Korea is an island country, and the price must be very high. In addition, Jeju Island is a popular tourist area (many Koreans loved to go on holiday in the past), and the price is higher than other places, so bring more money. You can ask the travel agency for details as a reference. It's best to talk to friends who have been to or lived in Korea recently and ask. I wish you a pleasant journey and hope to adopt it. Thank you.
