Is January Right for You?
Weigh the advantages and considerations before booking
- + From January to March, steady 15-20-knot northeast tradewinds fill the sails—prime time for skipping between Chuuk and Pohnpei without the bone-jarring chop that plagues the rest of the year.
- + January is the Caroline Islands’ whale-watching jackpot: humpbacks breach within 200 m (656 ft) of the reef, and islanders swear this is when you’ll spot mothers guiding calves through the passes.
- + Hotel rates dive 30-40% after the Christmas rush, and the same dive shops that turned divers away in December suddenly have next-day slots open for Truk Lagoon’s ghost fleet.
- + Yap’s Mi'il Channel hits manta fever in January—cleaning stations host 15-20 rays on glassy mornings, and the water clarity is what serious shooters circle on their calendars.
- − Afternoon squalls sweep in every other day around 2 PM, dump rain for 45 minutes, and ground smaller boats; dive crews front-load departures to dodge the curtain of water.
- − Airfare hurts—you’re shoulder-to-shoulder with post-holiday crowds bound for Guam and Manila, so the Pohnpei run that felt half-empty in November is now jam-packed.
- − A handful of outer-island guesthouses simply lock up for January “maintenance”—family places on Ulithi and Sorol shutter until February when visitor numbers climb again.

Best Activities in January
Top things to do during your visit
Water temperature in January sits at 28°C (82°F) with 30 m (98 ft) visibility—the year’s sweet spot. The Japanese fleet wrecks are always there, but calmer seas in January let you drop onto the deeper I-169 submarine and the Fujikawa Maru without increase that complicates penetration dives later. Most operators run two-tank morning trips to beat the weather window.
The basalt city looks its best under January’s humidity—the moss-covered stones glow emerald, and kayak channels between islets hold enough water. Local guides aim for 7 AM when the tide cooperates and the sun hasn’t yet turned the air into a steam room. Allow 3-4 hours door-to-door, including the 30-minute boat hop from Kolonia.
January pulls the largest manta mobs to Mi'il Channel—15+ rays in one sweep, including “Big Bertha,” photographed here for two straight decades. The channel drops to 15 m (49 ft) with coral heads rising to 3 m (10 ft), so strong swimmers can duck-dive for frame-filling shots. Boats push off at 6:30 AM to beat both crowds and weather.
January’s higher tides open the mangrove tunnels around Sokehs Island—paddle 5 km (3.1 miles) of waterways that bake dry by summer. Launch early before the trades pick up; juvenile reef sharks glide beneath the roots while endemic Pohnpei lory parrots chatter overhead.
January is village thanksgiving month—real sakau ceremonies replace tourist pageants, and you’ll join breadfruit harvests, watch coconut oil pressed by hand, and hear elders recount Japanese occupation days from memory. Tours run 4-5 hours with transport included.
January Events & Festivals
What's happening during your visit
January 11th explodes in Kolonia with stick-dancing parades, canoe sprints, and the year’s largest public sakau circle. The governor’s reception dishes breadfruit and reef fish fresh from earth ovens. Be on the parade route by 9 AM and plan to linger at the cultural center into the night.
