The best time to visit Supai is during the spring (late March to May) and autumn (October to early November) when the weather is most pleasant for hiking.During these seasons, the daytime temperatures are generally mild, ranging from 15°C to 25°C, making the trek to Havasu Falls and exploring the surrounding area much more comfortable. The cooler temperatures also mean less risk of heat-related issues, which is important given the strenuous nature of the hike. The natural beauty of the area, including the vibrant blue-green waters, is particularly striking during these times.Summer (June to September) can be extremely hot, with temperatures often exceeding 35°C, and there's a higher risk of flash floods due to monsoon rains. Winter (late November to early March) brings colder temperatures, shorter daylight hours, and potential for snow, which can make the trails more challenging and less enjoyable.
