Is December Right for You?
Weigh the advantages and considerations before booking
Advantages
- + Mid-December kicks off coral spawning season, think of it as the ocean's version of a snowstorm. Reefs explode into drifting clouds of pink and orange, the kind of spectacle divers circle on calendars years in advance.
- + Island ferries switch back to the full timetable after November's maintenance shutdown, slicing the trip to Marovo Lagoon to 2.5 hours. Try this in cyclone season and you're looking at a brutal 4-hour battering.
- + Post-harvest yam festivals light up villages across Malaita. Earth-oven smoke drifts 200 m (656 ft) ahead of the feast, and bamboo flutes, heard only once a year, cut through the air like ancestral voices.
- + Hotel rates tumble 25-30% from peak season. Waterfront lodges in Gizo suddenly have rooms, no six-month advance booking required.
Considerations
- − Afternoon thunderstorms slam in at 2:30 PM like clockwork. Forty-five minutes later, Honiara's dirt roads have turned to knee-deep mud that devours flip-flops whole.
- − Warmer currents nudge box jellyfish toward the shoreline. Locals won't volunteer the warning, you have to ask outright, and by then you may already be nursing the welts.
- − Christmas week shrinks domestic flights to a lottery. Solomon Airlines keeps just three planes flying for the whole country, every seat grabbed by islanders racing home.
Best Activities in December
Top things to do during your visit
Marovo Lagoon Liveaboard Diving Tours
December delivers 30 m (98 ft) water clarity, and coral spawning paints the lagoon like an underwater aurora. Liveaboards drop anchor inside the double-barrier reef where Christmas tree worms flash neon green and giant clams slam shut like lazy bear traps. You surface to wood-fired fish on deck while flying foxes flap across the sunset.
Booking Tip: Reserve 10-14 days ahead with liveaboard operators. They run 3-night and 5-night circuits tied to specific moon phases. Pick boats carrying marine biologists who know the spawning schedule down to the hour.
Vilu War Museum Cycling Routes
December dawns cool enough for cycling, 26°C (79°F) at 6 AM, before humidity cranks the dial. The road from Honiara to Vilu threads past Japanese tanks and American aircraft wrecks frozen in place since 1943. Kids sprint beside your bike shouting 'white man' while old men point out foxholes their fathers dug.
Booking Tip: Rent mountain bikes from Honiara shops, not the rusted beach cruisers hotels stash. The 25 km (15.5 mile) out-and-back eats three hours with stops, so roll out by 6 AM to beat both the heat and the afternoon storms.
Skull Island Cultural Tours
December's lower tides expose the sandbar linking Skull Island to Vonavona Island. You wade ankle-deep while reef sharks prowl the shallows. The skull shrines hark back to headhunting days, and your guide's grandfather was among the last warriors. Copra oil and frangipani scent the bone shrine. Shift in the breeze and you'll catch the village earth ovens firing lunch.
Booking Tip: These tours hinge on tide tables. Check the calendar posted at Munda airport and book 2-3 days ahead. The window spans three hours either side of low tide. Guides refuse to run if the sandbar is under water.
Tetepare Island Conservation Tours
December is nesting time for the island's tagged leatherback turtles. You patrol beaches by red flashlight while 400 kg (882 lb) females dig nests with flippers like shovel blades. The eco-lodge runs on solar power alone. At low tide the reef flat turns into a 500 m (1,640 ft) buffet of giant clams and bumphead parrotfish. Fruit bats brawl over figs above your mosquito net all night.
Booking Tip: Conservation tours operate in fixed 4-day blocks, capped at 8 visitors. Contact the Tetepare Descendants' Association directly, they favor researchers and repeat guests, so keep calling.
Honiara Central Market Food Tours
December piles green-skinned pomelos the size of your head next to taro roots still warm from earth ovens. The market fires up at 5 AM when fishmongers hack yellowfin tuna with machetes. By 7 AM, betel-nut smoke hangs blue and sharp, smelling of pepper and chalk. Try smoked flying fox, gamey bacon in disguise, while sipping fresh coconut water and watching grandmothers haggle like Wall Street pros.
Booking Tip: Hire guides raised in the market. They'll steer you to stalls tourists never find, like the woman who whips up sago-palm pudding in coconut cream. Arrive 6-9 AM, before the heat turns the place into a furnace.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The Honiara-Auki ferry sails twice weekly. Locals book at the shipping office behind the market, skipping the main terminal where tourists queue.
Village guesthouses serve reef fish and taro for a fraction of hotel prices. Pick ones with solar panels and rainwater tanks, they're cleaner.
The best snorkeling hides away from the famous sites. Ask boat captains about 'bommies', lone coral heads where they've fished for decades.
Island time is real. The 8 AM flight might lift at 7:30 AM if everyone's early, or 10 AM if the pilot's cousin needs a lift.
Avoid These Mistakes
Don't assume plastic will save you, when the internet drops in Honiara, even the supermarket in the main mall can't swipe your card.
Skip the 24-hour layover buffer at your peril; Solomon Airlines cancels so often that locals quit glancing at the departure board years ago.
Leave the board shorts at the guesthouse. Men need shorts that at least graze the knee, women need skirts below it, and anyone in swimwear will be politely escorted out of a village feast.
