June is hot and sunny, but also humid and wet in the summer of Nebraska. The brilliant 10 to 11 hours of daily sunshine also see periods of dark cloudy skies that bring heavy showers. Thunderstorms are frequent and often bring torrential rain. Landspouts occur occasionally and arouse the interest of tourists who are unfamiliar with the phenomena. June is the rainiest month of the year with 5" (127mm) to 7" (178mm) of rainfall in many places. The average high temperatures soar in the 78°F (25.6°C) to 83°F (28.3°C), while the average low temperatures are in the temperate zone of 58°F (14.4°C) to 63°F (17.2°C). Tubing from Cody Park down the North Platte River is a popular activity and takes several hours in the scenic waters. Grab a sunscreen or the shelter of shade during the hot mid-day period. Keep an eye on the weather forecast as sudden storms catch visitors by surprise. Light summer clothing is suitable during June days in Nebraska, but an umbrella helps counter the rain.
