June begins the hot summer season in Utah, with the sun rays gradually rising in intensity. The wilderness and natural beauty of the state draw tourists from distant lands. The average high temperatures are between 63°F (17.2°C) to 96°F (35.6°C), while the average low temperatures are in the 38°F (3.3°C) to 67°F (19.4°C) zone. Green River in the south registers comfortably warm average temperatures in the 55°F (12.8°C) to 93°F (33.9°C) zone. Humidity levels are low, particularly in the arid west, and the skies remain clear during the night. Moderate rain to the tune of 1 to 2" (51mm) accumulates. Thunderstorms are frequent in the afternoon, and tornadoes make an unexpected visit to Utah. A cloudburst can bring heavy rain in the span of a few hours and result in flash floods due to the inability of the soil and vegetation to hold any water. June sees the tourist season at its peak in Utah, with the temperatures still bearable during the days and comfortable in the nights.
