And you didn’t think Alaska was going to make this list. Actually, Alaska and Hawaii both have statewide highs of just 100 degrees, exactly. While Kona, Hawaii, is one of the warmest climates in the U.S., following close on the heels of Florida, the continued tropical breezes keep it from heating up too much. The 100-degree high recorded at Fort Yukon, Alaska, in 1915 still stands as the hottest day in Alaskan history.
