July is usually the hottest month of the year in Utah, with blistering sunshine that scorches the land. The average high temperatures are in the hot 72°F (22.2°C) to 101°F (38.3°C) range, and many places remain over 100°F (37.8°C) for extended periods. Summer nights are surprisingly comfortable with average temperatures in the 46°F (7.8°C) to 75°F (23.9°C) zone. Tourist footfall is on a high in Zion National Park in the west, even though the temperatures are in the hot 69°F (20.6°C) to 101°F (38.3°C) range. Camping grounds and mountain lodges scarcely remain vacant as camping, fishing, biking, and trailing gain momentum. Mountains and canyons are cooler by up to 20°F (-6.7°C) than the surrounding lands. Rainfall is scarce, and the atmosphere is dry, with the average humidity below 50%. Brilliant sunshine makes light summer clothing with full sleeves and broad-brimmed hats the best way to combat the sun. Mornings are the best periods for outdoor trips during the day. Evenings have plenty of daylight and lots of fun activities in Utah in July.
