The Northern Territory is a land of extremes—particularly the Top End (encompassing Darwin, Katherine, Kakadu, and Arnhem Land), where there’s a tropical climate with two distinct seasons, each with its own sights and experiences. Most visitors come in the dry season, between May and October, when the weather is cooler and there’s more access to area attractions. The wet season, however, is the time for waterfall chasers, storm watchers, and seekers of peace and quiet—the area virtually shuts down. The Red Center (including Alice Springs, Tennant Creek, and Uluru Kata-Tjuta National Park) features four typical seasons; summer (December through February) is the hottest (and notorious for sand flies) while winter (June through August) tops out at around 70 degrees Fahrenheit. Visit Uluru between May and September when you might just see “the Rock” rushing with waterfalls.
