Utah Weather

The beginning of September can still bring hot days, but this is generally when temperatures start to cool. There are approximately six days of rainfall and daylight hours dwindle. Leafs start to change color in September and really hit their stride by October. In October, temperatures continue to cool, leaves continue to change color and snow begins to fall, though it usually doesn’t accumulate. By November, temperatures have gone from warm to cold and rain falls for nine days on average during the month. Snow begins to accumulate in the mountains and ski resorts tend to open toward the end of the month.

March begins with cold weather at the start of the spring season in Utah. Early spring is prone to cold fronts, and the arid land has sizable daily temperature differences. A moderate amount of rain falls in March, and the rest takes the form of snow. In April, temperatures rise with the advance of the spring season in Utah. Measurable snowfall recedes and most ski resorts end operations mid-April. Spring blooms, rain showers and increasing sunshine dominate the last two weeks of April. Typically, May is a very pleasant month across the state. Temperatures are moderate, the length of the days and sunshine are longer and there are enough rainstorms to keep it cool.

In June, summer kicks off with enjoyable temperatures, abundant sunshine, and occasional rainfall. June has the longest days of the year, peaking at 15 hours of daylight on the summer solstice. July and August are the warmest months of the year with the same range of average high temperatures. These are the driest (least humid) months with the least amount of rainfall.

Winter lasts from December through February with long periods of snowfall, freezing temperatures and short daylight hours. December and January are the coldest months of the year. The shortest day is December 21, (winter solstice) with just nine hours of daylight. February brings a mix of winter and spring weather with sneak peeks of warmer temperatures and more sunshine.
