September in Dhanushkodi is the Bay-storm tail. Rainfall remains at 90-110mm across 11-13 wet days, daytime 30-32C, nights 27C, humidity 82 percent. Bay-side wind eases through the third week as the southwest monsoon retreats from the wider sub-continent (formal withdrawal around September 25-30). The 8km Arichalmunai-tip sand track conditions improve as overnight rainfall reduces; the 4WD-jeep service from the aggregator desk runs conditional go/no-go through the first half, with reliability climbing through the back half. The Kothandaramaswamy Temple accessible by road most mornings. The ghost-town ruins at the tip visible from the road end; the 200m walk to the wave-collision point opens on clear afternoons. Adam's Bridge horizon line returns to visibility on the last week's clear dawns. The trip-defining tip-visit runs at 50-60 percent reliability through the month. Stay in Rameswaram — Daiwik Hotels ₹2,000-3,500, Hyatt Place ₹3-4,500, beach homestays ₹600-1,000. The October 15 onward window — Bay calmed, sand track firmed, full 4WD service — is dramatically better. Skip unless on a locked-itinerary Char Dham circuit with rain-day flexibility.
