<human>: I've heard that the weather in the United States varies from region to region. Can you tell me which regions are the warmest or coldest?
<bot>: The average temperature of the US is about 68 degrees Fahrenheit, with some areas being slightly warmer and others slightly cooler. However, there are a few regions where temperatures can be significantly higher or lower than this average. For example, parts of Alaska have an average annual temperature of around 60 degrees Fahrenheit while the southwestern deserts of the country see average temperatures below freezing.
