4. Late April: Crystal Clear Horizons
The Uyuni Salt Flats show differently as April comes to an end; much of the surface water has evaporated, exposing the complex hexagonal patterns of salt crystals. This time provides great clarity across the flats and fresh, pure air that makes landscape photography ideal. Traversing the salt flats is easier on the dry surface, which lets guests investigate more isolated sites and unusual formations. Daytime temperatures stay pleasant at about 60°F (16°C), however evenings may be somewhat chilly and dip to almost freezing. Perfect for stargazing and night photography, the sky at this period are especially brilliant and almost completely free of clouds. Strong visual effects are produced by the white salt surface against the deep blue sky. With more regions of the salt flats safely accessible, tour operators may provide longer trips to islands and caverns within the salt desert. The better conditions also help one to find uncommon Andean foxes and viscachas on the edge of the flats. For those interested in geology, this time is great since the exposed salt patterns and formations are obviously visible and interesting to examine.
5. Early May: The Perfect Mirror Effect
One of the most amazing events at the Uyuni Salt Flats early May is the flawless sky mirror effect. This time combines perfect conditions whereby a thin film of water stays on some areas of the surface of the salt flat, producing an exact mirror of the sky above. Particularly at sunrise and sunset, the constant temperature and low wind of the weather create glass-like surfaces that create amazing mirror effect. Perfect settings for photography are produced by bright skies, mild temperatures around 55°F (13°C), and low precipitation. Usually only a few centimetres deep, the thin water layer lets one walk easily while preserving the reflecting surface. Professional photographers and filmmakers trying to get the ideal mirror shots find great popularity in this time frame. Often snow-capped at this season, the neighbouring mountains and volcanoes give the reflections great dramatic impact. Early morning walks are particularly fulfilling since the dawn produces amazing colour displays exactly reflected on the surface of the salt flat. Less visitors than during the peak rainy season imply greater chances for continuous photographic sessions and quiet meditation on this natural beauty.
6. Late June: Winter Wonderland
Late June brings winter to the Southern Hemisphere, therefore changing the Uyuni Salt Flats into a striking, lovely scene. The salt crust is totally dry and solid during this time, producing an otherworldly white desert that reaches horizonally. With very low humidity and virtually no precipitation, the winter season presents the best sky of the year. While nights can dip much below freezing, producing amazing frost patterns on the salt surface in early mornings, daytime temperatures hover about 50°F (10°C). The great temperature differences between day and night lead the salt to contract and expand, creating especially beautiful polygonal patterns. Dramatic landscape photography would find ideal contrast and shadows produced by the winter light. The dry conditions allow one to visit once unreachable sections of the salt flats, including distant caverns and old coral formations. This is the time when star visibility is highest, hence it is perfect for evening trips and astrophotography. The clean air and great visibility let guests observe the nearby Andean mountains with remarkable clarity, therefore offering amazing panoramic vistas.
