Are there any weather conditions I should be aware of when planning a trip to Korea?

I am just wondering if there is a better/worse time of the year to go to Korea for work. 

I don't really see anyone mention the weather. I am not sure how it is over there at all. I have been to Japan and I know they have Hurricane seasons. 

Are there any weather conditions I should be aware of when planning a trip to Korea?

Most people try to avoid the really sticky and humid monsoon summer months. it's a lot more pleasant in the spring and fall, and a lot of peope tend to go during the winter.

I actually looking into this! March to May is probably the most beautiful time to go just for the cherry blossom season. You want to avoid June to August as mentioned, that is the monsoon season and it is not pleasant. Also I read that January and February are the cheapest months to go but it is cold outside.
