Utah's climate can be divided into four types: desert, semi-arid, humid continental/hot summer and undifferentiated highlands. Mountains in the north and true desert in the south each have distinct weather patterns.
October weather ranges from spring-like temperatures in the south (70 to 80 degrees Fahrenheit) to crisp fall temperatures in the north (an average of 64 degrees in Logan). Expect rain in the lower elevations and infrequent snow in the higher elevations.
October is a recommended travel time in Utah because temperatures across the state range from the mid-60s to the low 80s in comparison with summer temperatures that are between 70 and 102 degrees, with winter a chilly 30 to 54 degrees.
Utah is essentially a desert with areas of true desert in the south and high desert in the north. As such, temperatures vary considerably in a 24-hour period. Travelers should be prepared with many light layers of clothing to be dressed appropriately at all times of the day.
In 2004, precipitation in six areas across Utah exceeded the 100-year average return interval (the average time between occurrences of high precipitation) and helped reach the average water year total with just two storms.
