It's because Limestone does not have air conditioning in it's classrooms.
"The heat doesn't affect just concentration, it affects the mood of some students," Bloyd said.
"Yesterday was so hot and muggy in the building that it was just really unbearable. Not a lot of learning goes on when it gets hot like this," said Principal, Jill Warren.
She scheduled an early release day on Wednesday because of the heat.
That only goes so far, during class time the only relief is open windows and the six fans Bloyd has running all day. Fans that Bloyd paid for out of his own pocket.
Warren doesn't see air conditioned classrooms any time soon.
"Well in this day and age with the tight budget and Illinois not paying the schools the money that we need, I don't see that happening," she said.
Warren and Bloyd say they can just hope that cooler fall weather gets here soon.
