June is warm and bright in the summer of Minnesota, with the average temperatures in the 44°F (6.7°C) to 81°F (27.2°C) range. The southeast is the hottest region, with temperatures rising to 90°F (32.2°C). The sprawling wilderness attracts crowds in search of hiking and camping trips. The waterfalls roar with the addition of several million gallons of freshwater. Much of the water finds its way to many of the lakes and rivers in the state. Much of the snow disappears from the ground, but there is a significant increase in precipitation. June is also the season of thunderstorms and tornadoes, and tourists need to keep an eye on the weather. Flash floods are frequent in the mountains when the rainfall is heavy. The conditions are suitable for biking, fishing, and boating in the numerous lakes, and to explore a large number of state and national parks. Pack a rain jacket to be in charge of the summer in June in Minnesota.
