Things to Do in Marshall Islands in January

January's slack tide and cooler water let you drift above giant clams inside Arno Atoll's inner lagoon. You glide 2 km (1.2 miles) with the incoming flow while guides flag eagle rays weaving between bommies. The low sun makes coral colours explode without the March glare.

Cooler mornings mean you can knock out the full 48 km (30-mile) loop without melting. En route you'll pass rusting Japanese coastal guns at Laura, half-buried LVTs, and the skeletal radar tower at Rita, spots unreachable except by bike or pricey taxi. January breezes pin the coral dust, so photos stay crisp.

January visibility regularly tops 30 m (100 ft) on the Pacific wall off Mili Atoll. The thermocline slips to 24 °C (75 °F), so grey reef sharks orbit cleaning stations in gin-clear water instead of the usual green soup. It's the lone month you'll clock both manta rays and schooling barracuda on one dive.

With the trades muted, paddling a korkor across the lagoon feels like meditation, not cardio. Guides pole you through mangrove fingers behind Delap Park at dusk. Water turns glass-smooth and the only soundtrack is distant laughing gulls. You'll sip cooler sea spray and watch fruit bats cut black shapes across a mango-orange sky.

January's smaller swell lets you kayak inside the protected lagoon to the Prinz Eugen stern, still upright with propellers 5 m (16 ft) below. The steel stays cool enough to grip at noon, and you dodge the 20-knot gusts that March throws in. Pair it with a drift-dive on the USS Mississinewa oil tanker for the full WWII fix.
