Joshua Tree in June: what the park service says
June 15 starts Joshua Tree's annual campfire ban, which runs until October 1, and Belle and White Tank campgrounds close temporarily for the summer. The park advises four liters of water per person, plus more for cooling off, because the central part of the park has no drinking water; fill up at the West Entrance Station, Black Rock or the Joshua Tree Visitor Center. The park says sunrise and sunset are usually the best times of day to enjoy the desert in summer, and recommends sunglasses, long sleeves and a hat.
