The 8 hours of sunshine is bright, but the humidity is at a yearly high with a lot of cloud cover.
Mountain lodges and state parks are popular tourist places along with the coast. Mountain air offers a pleasant change from the heat of the plains as visitors flock to the highlands during July in South Carolina.
