With its gorgeous green spaces and amazing mountain views, Salt Lake City is considered one of the best places to live in the Pacific Northwest. Home to 200,567 people, Utah’s capital city is known for its liberal leanings and diverse population. So what is the weather like in the City of the Saints?

A lot of people think that weather and climate are interchangeable. However, though they are related, they each have different meanings. Climate refers to weather conditions over long periods of time, while weather describes the atmospheric conditions on a day-to-day basis. It’s important to look into both weather and climate when moving to a new area so you know what to expect.

Salt Lake City Seasons

SLC’s climate is significantly affected by the Great Salt Lake after which it’s named. Depending on the lake’s conditions, the city will receive significantly more or less precipitation. The summer months in SLC last from June to September. The winter months last from November to March. Spring is from March to June, and Fall is from September to November. Here’s what kind of weather you should expect from season to season in Salt Lake City:

Winter in Salt Lake City

Winter in SLC is cold and humid with lots of snow. Temperatures can drop to or below freezing. The city receives an average of 56.2” of snow a year, which mostly falls between November and February.

Spring is relatively pleasant in Salt Lake City. There is still a chance of snow through mid-April, but temperatures rise to daily highs of 61.5°F in April and a pleasant 72°F in May. The UV index can reach 9 or 10, so take precautions if you’re going to be in the sunlight between 10am and 4pm.
