Uyuni hava durumu: Mart

Forum posters describe Bolivia's rainy season as running roughly late December through March, with March still solidly within it though conditions improve noticeably as April approaches. Posters specifically discussing the Altiplano, where Potosí sits, note rain here usually isn't a major problem for city-based travel, though it's still wise to build in a few spare days for potential delays. Posters describe the typical pattern as heavy afternoon rain for a few hours rather than an all-day event, with rains generally easing toward the end of March. Posters do caution that March isn't ideal for trekking or mountain excursions specifically, since peaks are often shrouded in cloud this time of year. Posters generally rate March as still rainy but genuinely improving for Potosí, city sightseeing more reliable than mountain-based activities.

Uyuni's forum is clear that by May the famous mirror effect on the salt flats is no longer reliable - that's really a December-through-March phenomenon, and much of the salar has dried out by this point, though a lucky visitor might still catch some water in patches. A rain jacket becomes unnecessary this time of year, but nights turn genuinely brutal - one traveler reported around -10C at 4,400m elevation. The honest framing from regulars: come for the dry, otherworldly salt-flat scenery and star-filled skies, not for a shot at the reflection photos, and pack serious cold-weather gear regardless of how warm the days feel.

Forum posters give genuinely mixed advice on November - some call it a good window since the rains typically haven't started yet, meaning full access to sights like Fish Island (Isla Incahuasi) and an overnight stay at a salt hostel that become impossible once the salt flat floods; others frame November as already rainy-season-adjacent, with a real risk of transport disruption especially in the surrounding highlands. Posters are consistent that the classic mirror-reflection photos require standing water on the salt, which typically doesn't happen until the wetter February-March window - so November visitors should expect the dry, cracked salt-flat look rather than the famous reflection shots. Nights are described as genuinely freezing regardless of the exact date, with extra blankets provided at accommodations and posters confirming a sleeping bag generally isn't necessary given that provision.
