Monsoon

Good

October works.

India's side of the same sea, on the same southwest monsoon calendar.

The year here

JFMAMJJASOND

Best here: December, January, February, March, April.

Andaman and Nicobar Islands. Written by hand from how the season actually runs, calibrated against what the boats do, since a season that disagrees with the operators is wrong however good the meteorology behind it. It describes most years, not this one: the forecast above is what knows about next week.

Moon and tides

Waning gibbous

72% lit · day 20 of the lunar month

Neap tides

Neap tides — the smallest range of the month, so the weakest currents. Easy conditions and usually the clearest water, though a drift site may barely drift.

New 10 Oct Full 26 Oct

Phase computed here, not fetched. This is the spring/neap cycle, which sets how hard the water moves — not a tide table: no free source publishes high and low water for Southeast Asian reefs, and the range peaks a day or two after the moon does, by an amount that varies with the coast. For times on the day, ask the operator.

📍 Duncan's Wreck on Google Maps 🧭 Route from Port Blair

Times marked ~ are estimated from straight-line distance and will be roughly right at best. The road legs are the ones Google Maps answers properly; it will not plan the ferry or the dive boat at all. A dive site's coordinates put a pin in open water, so the map link drops you on the site, not on a jetty.
