Clima en Flying Fish Cove (The Settlement) en mayo

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.
