Query: What divides Florida two climates 
Context: The climate of Florida is tempered somewhat by the fact that no part of the state is distant from the ocean. North of Lake Okeechobee, the prevalent climate is humid subtropical (Köppen: Cfa), while areas south of the lake (including the Florida Keys) have a true tropical climate (Köppen: Aw). Mean high temperatures for late July are primarily in the low 90s Fahrenheit (32–34 °C).
