Traveller notes on Flying Fish Cove in December
Other months in Flying Fish Cove
There isn't much March-specific forum detail for Flying Fish Cove, but the island's wet season runs roughly December through April, so March sits squarely in it - a nearby thread about the wet season generally summed up the local attitude well: it won't stop you from hiking or diving, and getting rained on somewhere this warm is more refreshing than a nuisance. The destination's own climate record backs that up with frequent, warm showers rather than anything approaching a washout month, and the diving and red-crab-season scenery stay a big draw regardless of the rain.
Forum posters flag September-October as a genuinely unique feature of a Christmas Island visit: the famous red crab migration, when the sheer number of crabs moving toward the sea to spawn is prolific enough to force road closures across the island. Posters consistently name this drier stretch of the year, ahead of the wet season that sets in around December, as a favorable window weather-wise for exploring both Flying Fish Cove and the island's national park. Posters generally recommend planning around the migration itself as much as the weather, since road access can be genuinely affected by crab movement during a September visit regardless of how clear the skies are.

Red crab migration
15 Oct – 15 Jan · usuallyWildlife seasonClosuresBook earlyMillions of crabs leave the forest with the first rain and walk to the sea, and the cove is one of the easiest places to stand in the middle of it. Roads close at short notice, spawning happens before dawn on the last quarter of the moon, and the start date moves with the rain. Source ↗

Cyclone season
1 Nov – 30 Apr · usuallyClosuresStorms in the wet half of the year bring big seas into the cove, which is the island's only sheltered landing. When the swell is up the cargo cannot come off and the boat dives stop. Source ↗

Baby crabs come ashore
20 Nov – 20 Feb · usuallyWildlife seasonAbout a month after spawning the young crabs come out of the sea and head inland in a red carpet a few centimetres deep. In a good year it is the better half of the spectacle, and in a bad one it barely happens. Source ↗
