American Cities With Most Uncomfortable Temperatures
Every major city in the United States enjoys many days each year with mild temperatures, but some cities less often than others. Here you'll find temperature data and rankings for the major cities in America that most often feel unpleasantly cold or uncomfortably hot.
These ratings use long-term temperature averages based on weather data collected from 1991 to 2020 for the US National Centers for Environmental Information. The major cities included in these weather rankings represent the 56 metropolitan areas in the United States with the most people, all those with over one million residents in 2020, according to the US Census Bureau.
Most Days With Unpleasant Temperatures
Less that comfortable temperatures are highs that fall outside the pleasant range of 60 to 80 degrees Fahrenheit. Some cities like Miami are warmer, and commonly have days in the 80s or 90s. Others, like Minneapolis, spend most the time below 60. For people who like their weather either on the hotter or colder side, those cities are ideal. The 60 to 80 degree span though is for most people closer to a pleasant room temperature.
These 15 cities average more than 250 days, over two-thirds of a year, when the day's highest temperature falls outside the ideal range for comfort because it's either too hot or too cold.
