Main season for South Utah is summer! Highest temperatures can be expected during these months as well as high prices for accommodation. Best time to travel is late spring and fall when temperatures become moderate and parks are not that crowded.
Winter time brings the main season for Salt Lake City and the ski resorts. The summer temperatures are much more moderate than in the south, so it's a good idea to visit the Salt Lake area in summer if you are not a skier.
Climate and Temperatures
With regard to the climate Utah can be split up into 3 regions.
North-East (Salt Lake City area): the Rocky Mountain Region with mountains up to 4.000 m (13.000 ft). This is the skiing area of the state.
West and South West: the Utah Basin, which is the lowland, the plains. Temperatures here are high and the air is dry - it's said it is one of the driest places in the US. The region is home to the Great Salt Lake, which is always worth a visit.
South and Southeast: the Colorado Plateau (Highland) which extends into neighbor state Arizona. This is the area where the major National Parks like Bryce Canyon, Zion etc. are located. Temperatures as well very high during the summer and the air is dry. Winters can be freezing cold, due to the elevation.
Southeast Utah is part of the Colorado Plateau, a "high desert" region that experiences wide temperature fluctuations, sometimes over 40 degrees in a single day. The temperate (and most popular) seasons are spring (April through May) and fall (mid-September through October), when daytime highs average 15 - 25 degrees C (60 to 80 F) and lows average -1 - 10 degrees C (30 to 50 F).
Summer temperatures often exceed 38 degree C (100 F), making strenuous exercise difficult. Late summer monsoon season brings violent storm cells which often cause flash floods.
Winters are cold, with highs averaging 30 to 50 F, and lows averaging 0 to 20 F. Though large snowfalls are uncommon (except in nearby mountains), even small amounts of snow or ice can make local trails and roads impassable.
