June in Vedanthangal continues the closure. The TN coast sits in the SW monsoon rain shadow — only 50-70mm of light rain reaches the region across June and the tank level rises marginally to roughly 5-10 percent capacity. Daytime 28-36C, humidity 78 percent. The 30-hectare tank remains essentially dry; the Barringtonia trees re-leaf as the humidity rises but the migratory waterbird population stays at northern breeding grounds. TN Forest Department gate-shut. Madurantakam Lake (12km north) and Pulicat Lake (90km north) hold their resident waterbird populations through the SW monsoon residue. For Chennai birders, Pulicat is the strongest June alternative — flamingos in stable numbers, sandpipers and curlews, low visitor traffic. The sanctuary reopens around early November once the NE monsoon recharges the tank and the painted-stork migratory pulse arrives.

Why June scores 2.0/10
