The Midwest experiences the greatest temperature swings between summer and winter.

The Midwest, known for its continental climate, is characterized by dramatic temperature changes throughout the year. During the summer, temperatures can climb into the 90s and even 100s (°F), with hot and humid conditions. In contrast, the region faces harsh winters, with temperatures frequently dropping well below freezing and often reaching sub-zero levels. This extreme variation in temperature is due to the Midwest's inland location, far from the moderating effects of oceans, resulting in more pronounced seasonal changes than coastal regions or areas with more temperate climates.
