Planning a trip

8–12 days

worth going for

Long haul, usually two flights.

4,946km from Singapore — about 24h each way, so two of those days are travel. 6 dive sites within 25km.

When people dive it

Busiest Jul, Nov · almost nobody dives it Feb, Mar, May.

From 2,453 logged sightings — when divers are in the water, which is not quite the same as when visibility is best.

Dive Crew is a dive group from Singapore. Members plan trips here, log their dives, and share their photos of each site.

Season

Prime

October is as good as it gets here.

Southern hemisphere, so the calendar inverts: the good months are the ones that are cold at home.

The year here

JFMAMJJASOND

Best here: June, July, August, September, October.

The Great Barrier Reef and Coral Sea — no monsoon here; the season is rain and water temperature. 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

71% 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.

Getting there

~14h 30m

door to water, each way · 4 legs

Transferthe jetty~2h 48mRoad transfer to the coast, usually arranged by the resort or liveaboard.Directions →
Ferrythe crossing~2hAt this distance the last stretch is a scheduled crossing rather than a dive boat, so book it before the flight — a missed sailing usually costs a day. Which crossing it is has been worked out from the distance and not from a timetable; ask the operator.

📍 Lighthouse Bommie on Google Maps 🧭 Route from Cairns

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.
