Vedanthangal Bird Sanctuary in August
Tamil Nadu, India
Monsoon rains flood the sanctuary, displacing birds to other wetlands
August in Vedanthangal continues the closure. The SW monsoon residue adds another 130-160mm across the month — the 30-hectare tank fills to roughly 30-40 percent capacity, the Barringtonia stands stand fully leafed and ready, but the migratory waterbird population remains at northern breeding grounds. Daytime 26-32C, humidity 80 percent. TN Forest Department gate-shut. Madurai Aadi Perukku (August 3, Cauvery river-bank festival) is observed across Tamil Nadu; the Vaishnavite community at the nearby Madurantakam temple stages traditional water-related rituals on the day. For Chennai birders, Pulicat Lake remains the strongest year-round alternative — 90km north on NH-16, day-trip viable from Chennai. The sanctuary reopens around early November once the NE monsoon delivers the tank-filling rains and the migratory waterbird arrival commences.
