I have been looking into tour that goes to South Korea August2-18. What can expect in terms of temperature, humidity and rain?

Hot, humid and a good chance for rain. However, the summer monsoon should be over.

Just how hot and humid??

My son just happened to be talking to his girlfriend in South Korea when I read this post so he asked her. She said last August in Masan it was 29C or 84.2F and very humid. My son said it was much more humid than in Honolulu in August(where he went to college). He lived in South Korea last August.
