I've been thinking about this for years. Have the Winter Olympics in February, as always. Host them in a country where the equator passes through, such as, Ecuador, Colombia, Brazil, Kenya or Uganda. This way, it will be hot, and the summer events like swimming, diving, track and field, etc. can take place in February. Then, have the August Summer Olympics in a place where there is snow all year round, like, Switzerland, Austria, or Canada. During the Summer Olympics, the winter events like skiing, bobsledding, and figure skating can take place in August.
