The climate varies along with the geography, from tropical (hot and wet in summer, warm and dry in winter) in Florida and Hawaii to tundra (cold all year) in Alaska. Large parts of the country have warm summers and cold winters. Most of the northern U.S. gets snow in winter. Some parts of the western United States, like parts of California, have a Mediterranean climate. The southeastern United States can get hurricanes. Parts of the southern United States are subtropical (hot in summer and cool in winter). Tornadoes happen a lot in the Midwest.
