The short answer
When to go to Nagarjuna Sagar
October to February is the best window: days are warm but manageable and the reservoir is usually full enough for boats and falls. March to May is hot, with highs in the high 30s and 40s at nearby Nalgonda, so sightseeing needs early starts. June to September is humid and wet, though a strong monsoon can open the dam gates and bring crowds. Older travellers will be most comfortable from November to February.
