Karaikal in September
Puducherry, India
September in Karaikal centres on the Velankanni feast (September 1-8) — the Tamil Catholic equivalent of a Marian pilgrimage that draws 1-2 million people to the basilica 27km south of Karaikal. Karaikal is the natural overnight base; hotel rates spike 50-70 percent for the September 1-10 window and book out 14-21 days ahead. Outside the feast window, Thirunallar runs normal Saturday crowds 18,000-25,000. Nagore Dargah Thursday qawwali at peak attendance. Daytime 25-32C, humidity easing toward 80 percent, rainfall 100-150mm — most of it the second-half pre-monsoon thunderstorms. The Cauvery delta paddy is at harvest stage from week 3; rural photography continues at year-best. The trip works for the multi-faith pilgrimage circuit; for general tourism, October is cleaner.
