Borra Caves in August
Andhra Pradesh, India
August in Borra Caves is more of July with slightly fewer extreme-rain days. Rainfall 250-300mm, valley 22-30C, humidity at 85 percent. The Kirandul Passenger holds a six-day timetable but landslide-led cancellations are common on the Sunabeda-Borra-Tyda stretch. Cave access remains gated by APTDC staff judgment on the heaviest mornings; expect 30-50 percent of August mornings to either close the chamber or limit it to the upper galleries above the slippery descent. Anantagiri's Wednesday tribal market continues — bus from Araku town gets through unless the previous day saw 60mm-plus. The valley itself runs at year-deepest green — coffee-plantation canopy, low cloud, mist on the Anantagiri viaduct — but the cave at the centre of the trip works only intermittently. October cleaner.
