The only way word to really describe today really is humid (습기있는). My classrooms have no windows and when the heat starts to go up everyone suffers. Today was really bad, almost but not quite insufferable.
Adding insult to injury was the fact that our manager has placed huge new air conditioners in the hottest rooms but we're not allowed to use them right now, and I don't know when we can. Not good for me and certainly not good for the students.
