This creates incredible photographic opportunities, and the clear skies often provide fantastic visibility, perfect for stargazing at night. So, prepare your camera and your sense of adventure, because you are in for a ride. Be aware that the wind can pick up during this time of year, especially in the steppes and desert regions.
