According to allcitycodes, the United States (U.S.) has a wide variety of climates ranging from tropical in Hawaii to arctic in Alaska. Generally, the U.S. experiences four distinct seasons with mild summers and cold winters. The average temperature during the summer months can range from 21°C (70°F) to 33°C (91°F) while winter temperatures typically range from -2°C (28°F) to 12°C (54°F). Rainfall is common throughout the country with most areas receiving an average of 100mm (4 inches) per month. Wind speeds are generally light but can become strong enough to cause damage during storms and thunderstorms which occur regularly throughout the year, especially during spring and summer months when tornadoes are also common over bodies of water such as the Great Lakes region. Snowfall is also common throughout much of the U.S., particularly in northern regions where snow can stay on the ground for up to four months a year. In addition, coastal areas of California and Florida are prone to hurricanes which can cause disruption to transport networks if they occur in populated areas. Fog is also quite common across much of the U.S., particularly in coastal areas due to its proximity to large bodies of water like the Pacific Ocean and Atlantic Ocean.
