Port Blair (Sri Vijaya Puram) in September
Andaman & Nicobar Islands, India
Ferry services remain unpredictable due to lingering monsoon swells, making island-hopping unreliable
September in Port Blair is a slow recovery from the monsoon hammering. Rainfall drops to 250-300mm with most of it falling in the first fortnight. By the third week, ferry services to Havelock resume on a six-day timetable, dive operators re-open with reduced staff, and skies start showing usable sun. Air 25-30C and humidity finally drops below 85 percent. The trip works - just barely. Dive visibility is recovering through 12-18m, hotel rates are at their year-low (often 60 percent off peak), and the islands are emptier than any other open month. Better suited to repeat travelers than first-timers.
Why September scores 4.0/10
Weather
Recovery month. Rainfall easing to 250-300mm. Ferries returning by mid-month. Still patchy.
