October in Tharangambadi is the proper season opener. The NE monsoon arrives in force from mid-month — rainfall jumps to 280-380mm across 12-14 wet days, but the temperature drop is dramatic. Daytime falls from late-September's 31C to 24-30C, granite of Fort Dansborg cools below 35C surface mid-day, sea breeze cool and reliable. The Danish Quarter walking circuit resumes its full shape from October 15 onward. Cyclone watch begins along the Coromandel coast — IMD monitors Bay of Bengal lows from October 1; Tharangambadi sits in the high-risk cyclone path. Cyclone Thane (December 2011) hit Cuddalore 90km north; Cyclone Gaja (November 16, 2018) hit Vedaranyam 60km south and devastated the Nagapattinam-Tranquebar coastal stretch — 60+ deaths, 80,000+ trees uprooted. The fort and church survived; Masilamani Nathar Temple had already lost its mukhamandapam to the 2004 tsunami. Track IMD updates via mausam.imd.gov.in. Hotel rates climb to 50-60 percent of December peak: Bungalow on the Beach ₹8-12k, The Gate House ₹5-8k, Nayak House ₹4-6k, basic homestays ₹2-3.5k. Strong call for first-time visitors who can tolerate occasional cyclone-watch days.
