The UV index in the United States varies widely, from low levels in northern states during winter to very high levels in southern states and during summer months. Coastal and desert regions often experience stronger UV radiation.
Seasonally, northern U.S. states have cold winters with snow and warm summers. Southern states typically have milder winters and hot summers with thunderstorms. The West Coast experiences wet winters and dry summers, while the interior states have more extreme temperature changes.
Compared to neighboring Canada, the U.S. generally has warmer temperatures and higher UV indexes, especially in the south. Mexico, to the south, has even higher UV levels year-round due to its proximity to the equator and mostly warm climates.
