The Northern Midwest is colder due to its higher latitude, meaning it is farther from the equator.

Regions like the Northern Midwest, which include states such as Minnesota, North Dakota, and Wisconsin, experience colder temperatures because they are located farther north. This higher latitude means they receive less direct sunlight, especially during the winter months, leading to longer, harsher winters. In contrast, areas like Southern California, the Gulf Coast, and the Southeast U.S. are warmer due to their more southern location, warmer ocean currents, and milder climates overall. The Northern Midwest's colder weather is directly linked to its geographical position.
