Point Calimere Wildlife Sanctuary in May
Tamil Nadu, India
Peak heat and humidity make wildlife viewing nearly impossible in May
May in Point Calimere is full closure at the year's harshest point. Daytime 29-39C with occasional 41C spikes, humidity 75 percent, sea breeze provides modest relief only after 5pm. The lagoon water levels reach their year-low — the Great Salt Swamp (Vedaranyam Swamp) dries to white-crystallised salt-pan, the Mudbank zone holds residual mudflat patches where blackbuck and chital come for the morning salt-licks, and the dry-grassland holds the year-round resident species. Pre-monsoon thunderstorms hit the last 10 days — short violent squalls that bring temporary respite but no lagoon recharge. The TN Forest Department maintains the closure. For Cauvery-delta birders, Pulicat Lake (year-round flamingo presence) remains the May alternative. The Vedaranyam fishing village (16km north of Kodikkarai) operates through the heat; the famous Vedaranyam salt-pan production hits its annual peak in the May-July dry-season. The sanctuary reopens early November.
