It is one of the driest states in the country with one of the lowest relative humidity percentages. In December the average highest relative humidity is The lack of humidity and moisture in the atmosphere makes the skies above Utah a deeper shade of blue. 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. 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.
Most people think of weather in terms of temperature, humidity, precipitation, cloudiness, brightness, visibility, wind, and atmospheric pressure. Climate is the description of the long-term pattern of weather in a place. Climate can mean the average weather for a particular region and time period taken over 30 years. Climate is the average of weather over time.

Weather is the conditions of the atmosphere over a short period of time, and climate is how the atmosphere is over long periods of time.
Weather is how the atmosphere is behaving and its effects upon life and human activities. Weather can change from minute-to-minute. Most people think of weather in terms of temperature, humidity, precipitation, cloudiness, brightness, visibility, wind, and atmospheric pressure.

Log In Sign Up. The growing season in Salt Lake City typically lasts for 6. Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature.
Based on growing degree days alone, the first spring blooms in Salt Lake City should appear around April 6 , only rarely appearing before March 24 or after April This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents.
Shortwave radiation includes visible light and ultraviolet radiation. The average daily incident shortwave solar energy experiences extreme seasonal variation over the course of the year. The brighter period of the year lasts for 3. The brightest month of the year in Salt Lake City is June , with an average of 8.
The darker period of the year lasts for 3. The darkest month of the year in Salt Lake City is December , with an average of 2. For the purposes of this report, the geographical coordinates of Salt Lake City are The topography within 2 miles of Salt Lake City contains significant variations in elevation, with a maximum elevation change of feet and an average elevation above sea level of 4, feet. Within 10 miles contains significant variations in elevation 5, feet.
Within 50 miles also contains extreme variations in elevation 7, feet. This report illustrates the typical weather in Salt Lake City, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, to December 31, There are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Salt Lake City. For each station, the records are corrected for the elevation difference between that station and Salt Lake City according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Salt Lake City is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Salt Lake City and a given station. To get a sense of how much these sources agree with each other, you can view a comparison of Salt Lake City and the stations that contribute to our estimates of its temperature history and climate.
Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data. All data relating to the Sun's position e. This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a kilometer grid.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: 1 are based on computer models that may have model-based errors, 2 are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and 3 have particular difficulty with the weather in some coastal areas, especially small islands.
We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
