Where to Watch the Moon's South Pole Region from India in August 2026

For those wanting to observe the Moon to honor the anniversary, India's dark sky reserves offer the best views. Locations like Hanle (Ladakh), Spiti Valley, the Rann of Kutch, and Jaisalmer provide excellent vantage points. However, it is important to note that August is peak monsoon season in most of India, so dense cloud cover is highly likely for many observers.
