Korea in Early June, how is weather like?

hi I am planning a trip for my parents to Korea.

Am wondering which is the best time to be in Korea?

I did a little reading and found out that it is not an ideal time to go in july because it is warm and humid... is this true for the summer? and if so... how would early June be like...? :)

Korea in Early June, how is weather like?

Early June weather should be around 25-30 degrees Celsius, with clear skies and sunny weather. July and August are warm but not as humid as Singapore. IMHO the best time to visit is November when the weather is plesantly cool 16-23 degrees and the trees start turning crimson.
