Average Monthly Rainfall
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.
As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Aurora experiences some seasonal variation in monthly liquid-equivalent snowfall.
The snowy period of the year lasts for 5.1 months, from November 5 to April 7, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around December 25, with an average total liquid-equivalent accumulation of 0.4 inches.

Best Time of Year to Visit
To characterize how pleasant the weather is in Aurora throughout the year, we compute two travel scores.
The tourism score favors clear, rainless days with perceived temperatures between 65°F and 80°F. Based on this score, the best time of year to visit Aurora for general outdoor tourist activities is from mid June to early September, with a peak score in the first week of August.
The beach/pool score favors clear, rainless days with perceived temperatures between 75°F and 90°F. Based on this score, the best time of year to visit Aurora for hot-weather activities is from late June to mid August, with a peak score in the third week of July.
For each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed.
Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies.
Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more.
Our tourism temperature score is 0 for perceived temperatures below 50°F, rising linearly to 9 for 65°F, to 10 for 75°F, falling linearly to 9 for 80°F, and to 1 for 90°F or hotter.
Our beach/pool temperature score is 0 for perceived temperatures below 65°F, rising linearly to 9 for 75°F, to 10 for 82°F, falling linearly to 9 for 90°F, and to 1 for 100°F or hotter.
The growing season in Aurora typically lasts for 5.2 months (159 days), from around May 5 to around October 11, rarely starting before April 14 or after May 28, and rarely ending before September 20 or after October 30.

This report illustrates the typical weather in Aurora, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Aurora.
For each station, the records are corrected for the elevation difference between that station and Aurora 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 Aurora is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Aurora and a given station.
The stations contributing to this reconstruction are: Milford Municipal Airport (31%, 110 kilometers, southwest); Hanksville Airport (26%, 121 kilometers, southeast); Carbon County Airport (24%, 127 kilometers, northeast); and Bryce Canyon Airport (19%, 137 kilometers, south).
