Autumn (April and May) - Trekking conditions in autumn are pleasant, with temperatures averaging between 12-27C. Unlike the winter months when evenings become quite chilly, autumn evenings are cool and trekkers can comfortably pull their swag out from their tents and sleep outside under the blanket of stars. While the official wet season is over, you can still expect rain up until late May, as well as some cloud coverage during these months.
Winter (June to August) - During the daytime, temperatures hover at low-mid 20C with refreshingly cool breezes, however evenings temperatures can drop close to 0C, particularly in the valleys, and the frost that covers the ground can create a snow-like appearance. Many people are surprised to find out how cold it can get in the middle of winter, so trekkers need to make sure they are adequately prepared for cold nights with insulated sleeping bags, beanies, gloves and thermal underwear.
Spring (September) - Temperatures in September begin to rise leading to sporadic thunderstorms which creates the perfect environment for the landscape to come alive with wildflowers and lowline flowering shrubs. With cooler temperatures suitable for hiking, and clear skies for picture-perfect sunsets, it's no surprise that September is a popular season to trek the Larapinta Trail.
