Why visit Salar de Uyuni during Apr–Oct?
April offers a chance of residual mirror effect with improving access to Incahuasi Island — the best of both worlds if conditions align. November is the start of rainy season; weather is unpredictable.
Shoulder season (Mar, Nov) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan–Feb, Dec) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
