During the southwest monsoon in 2025, continuous rain over Tirunelveli and Tenkasi prompted the district administrations to extend bans on bathing at Courtallam Falls (including Main Falls and Five Falls) for multiple days in May. Heavy inflows from monsoon showers increased river and waterfall discharge dramatically, leading officials to prioritize safety over tourism. Despite these restrictions, many visitors gathered near private waterfalls and dams, hoping for sightseeing opportunities — though authorities remained firm on the necessity of restrictions due to unsafe conditions.
