Is August Right for You?
Weigh the advantages and considerations before booking
- + August slides into the quiet pocket between summer family traffic and the winter surf rush—visitor numbers at Chuuk and Pohnpei dive sites drop by 30-40 percent, and once the early-month storms clear, the water often opens to more than 30 m (98 ft) of visibility.
- + Manta rays crowd Yap's Mi'l Channel in August; a month-long plankton bloom pulls dozens of them into the shallows, giving you shoulder-to-fin moments you will not find in June or December.
- + After the first week, hotel rates in Kolonia and Weno fall fast—beachfront rooms that demand 60-day advance booking in December suddenly pop up online with only 48-hour notice.
- + Island ferries that are packed with tourists in peak season now carry more locals than visitors; you will share deck space with sacks of betel nut and crates of Spam instead of cruise-ship excursions.
- − Roughly one day in three brings a sharp, 30-minute downpour—usually between 2pm and 4pm—that knocks out power across the island and turns dirt roads into slick red clay.
- − Outer-island flights already run on island time, but August storms can keep the 19-seat Dorniers on the ground for two straight days, so pad any itinerary with an extra 48 hours.
- − Humidity holds at 70 percent even after dark; cotton shirts stay wet long enough to grow salt rings and that unmistakable mildew smell by day three.

Best Activities in August
Top things to do during your visit
August’s plankton bloom cuts visibility a notch yet pulls in bigger pelagics—reef sharks circle the San Francisco Maru while spotted eagle rays drift above the Fujikawa Maru’s intact bow gun. Afternoon squalls help rather than hurt: they flatten the wind, giving you glassy surface conditions you rarely see in trade-wind season, and the wrecks lie shallow (12–40 m / 39–131 ft) so surface breaks feel like poolside pauses.
By mid-month visibility clears to 25 m (82 ft), turning Mi'l and Goofnuw channels into manta soup. The rays here are fearless—they barrel-roll within arm’s reach while feeding. August also coincides with stone-money ceremonies in outer villages, so after the snorkel you will taste fresh breadfruit and turmeric-stained sakau.
August rains keep the mangrove channels high, letting you paddle straight into the ancient canals without the usual muddy carry. The basalt ruins of Nan Madol steam after every shower, intensifying the wet-stone petrichor you will not catch in the dry months. Expect leeches—wear long socks and carry a pinch of tobacco for local guides to chew and spit as repellent.
The horseshoe-shaped Utwe-Walung Biosphere Reserve stays glassy until noon in August, letting paddles glide through tunnels of red mangrove where juvenile black-tip reef sharks zig-zag beneath the board. Afternoon rain cools the air just enough to keep sweat from dripping onto the deck, unlike May.
Humpbacks cruise past Ulithi’s western edge from late July through early September; in August you will hear them singing through the aluminum hull of the supply boat before you see the blows. Pods surface 2–3 km (1.2–1.9 mi) offshore, and the lagoon’s 25 m (82 ft) of visibility lets you free-dive and listen even if the whales stay out of sight.
August Events & Festivals
What's happening during your visit
August 1–3 brings traditional dances, outrigger canoe races, and fiercely spicy taro-leaf curry cooked in underground stone ovens. Visitors are invited to try betel nut—expect a mild buzz and bright-red spit that stains concrete for weeks.
August 13 marks the 1944 U.S. landing; villages host volleyball tournaments on packed-coral courts and roast whole pigs over coconut husks. The smell of burning husk and sizzling pork drifts across Kolonia harbor from dawn until the 9pm fireworks.
