9. Late September: Spring Awakening
In the Southern Hemisphere, late September marks the start of spring, therefore bringing slow changes to the Uyuni scene. While keeping the clear sky typical of the dry season, the temperatures start to climb somewhat; daily highs reach about 60°F (16°C). Extended excursions of the salt flats and neighbouring areas would find this period perfect since it provides great visibility and consistent temperature. Particularly among bird species getting ready for their breeding season, the rising temperatures bring more activity of wildlife to the area. Perfect settings for photography are created by the mix of rising temperatures and still-dry conditions; low atmospheric distortion and great light quality result Safe access to all sections of the salt flats allows tour operators to provide thorough trips including visits to cacti islands, volcanic formations, and historic coral reefs. The intriguing patterns the spring winds produce in the salt crust give photos unusual textures. Those who want to combine trekking and exploration of the neighbouring Andean landscapes with salt flat excursions will especially find this time to be ideal.
10. Mid-October: Prelude to Rain
As the area gets ready for the next rainy season, mid-October marks a special transitional time. First sporadic clouds start to show, painting dramatic sky above the still-dry salt flats. As daily highs approach 65°F (18°C), temperatures keep rising and outdoor activities become more pleasant. Especially at sunrise and sunset, the mix of rising humidity and still-clear circumstances produces amazing atmospheric patterns. This time allows photographers to catch striking cloud patterns reflected in any possible tiny water collection. The neighbouring desert plants start to show life, giving the scene subdued colours. Planning picture sessions becomes simpler as morning calm gives way to afternoon breezes, hence establishing more consistent wind patterns. As the hot season draws near, the visitor count starts to rise; still, the salt flats stay very empty in comparison to busy months.
