    “Feels-Like” Temperatures

    The way we experience weather isn’t all about temperature. Higher temperatures affect us much more at higher humidity, and colder temperatures feel piercing with high winds. Our perceived temperatures factor in humidity and wind chill to better represent how hot or cold the day feels to a person.

    Precipitation (Rain or Snow)

    If dry weather is what you’re after, the months with the lowest chance of significant precipitation in the United States are January, November, and then February. Note that we define “significant precipitation” as .1 inches or more in this section. The lowest chance of rain or snow occurs around mid January. For example, on the week of January 15th there are no days of precipitation on average. By contrast, it’s most likely to rain or snow in early to mid June with an average of 1 days of significant precipitation the week of June 11th.

    When can you find snow in the United States? Weather stations report very large amounts of snow likely to be deepest around July, especially close to late July. The best time to ski (if at all) in the United States is often around around July 23rd when fresh powder is deepest. Please note that a value of 0 for snow in the graph below may either mean there was no snow, or that snow is unreported.
