Is March Right for You?
Weigh the advantages and considerations before booking
- + March sits deep in the wet season, which means the Solomon Islands are at their most intensely green, the jungle canopy on Guadalcanal's ridgelines looks almost backlit, and the waterfalls along the Mataniko River run at full, thundering force. Photographers and anyone who wants to see these islands at their most alive will find the landscape in a state that the dry months simply cannot match.
- + You will likely have major sites nearly to yourself. The Solomon Islands barely registers on mass tourism circuits even in peak season, and March thins the trickle further. At Bonegi Beach, where two rusting Japanese transport ships sit half-submerged in the shallows, you might be the only person snorkeling the hull for an entire morning. That kind of solitude at an excellent wreck site does not exist in most of the Pacific.
- + Accommodation rates tend to drop noticeably from the already moderate baseline. Guesthouses and lodges around Honiara and the Western Province that fill during the June-to-September dry window often have immediate availability in March, and you will find more flexibility to negotiate multi-night stays or inclusion of boat transfers.
- + Reef fish activity picks up in the warmer, nutrient-rich wet season waters. Divers working the wrecks in Iron Bottom Sound, the strait between Guadalcanal and Tulagi where dozens of Allied and Japanese warships went down in 1942-43, report excellent visibility on calm days between storms, with coral growth on the superstructures at its most colorful and soft corals fully extended in the current.
- − March is the wettest month in the Solomon Islands by a clear margin. Honiara averages 14.3 inches (363 mm) of rain, nearly four times August's 3.6 inches (91 mm). Rain does not fall gently here, it arrives in vertical sheets that turn unpaved roads to mud in minutes and can strand you on the wrong side of a river crossing for hours. Inter-island flights with Solomon Airlines cancel or reroute without much notice when squalls roll through.
- − This is the heart of the South Pacific cyclone season, which runs roughly November through April with the statistical peak in February and March. A direct hit is uncommon in any given year. But tropical depressions and feeder bands bring multi-day stretches of heavy rain and rough seas that shut down boat travel between islands entirely. If your trip depends on reaching the outer provinces, Marovo Lagoon, the Shortland Islands, Rennell, you need genuine schedule flexibility.
- − The humidity sits at 86% on average and feels higher. Everything is damp: your clothes, your gear bag, the sheets on your bed. Mold colonizes leather and camera equipment within days if you are not vigilant. The combination of heat and moisture makes midday exertion punishingly hard, and the mosquito population peaks with the standing water, raising exposure to dengue and malaria in a country where both circulate year-round.
Best Activities in March
Top things to do during your visit
The jungle-covered ridges south of Honiara hold some of the most significant and least visited battlefields of the Pacific War, and March's wet conditions sharpen the experience. At Bloody Ridge, where a thin line of US Marines held against a Japanese assault in September 1942, the rain-soaked earth and dripping canopy give you a visceral sense of what those soldiers endured in conditions almost identical to what you are standing in. Shell casings and rusted equipment fragments still surface after heavy downpours. The humidity is punishing by midday, so the best operators schedule departures at dawn, when mist sits in the valleys below the ridgelines and the air still carries some coolness. Red Beach, where the first American amphibious landing of the war took place in August 1942, is a short drive east of Henderson Airport, and in March you will likely walk the black volcanic sand alone except for the occasional fisherman hauling in a morning catch. The rain rarely lasts all day, most storms blow through in intense bursts of an hour or two, so even on a fifteen-rain-day month, you can usually find windows for outdoor touring if you stay flexible.
Iron Bottom Sound earned its name the hard way, at least 50 warships and hundreds of aircraft from both sides went down in the waters between Guadalcanal, Tulagi, and the Florida Islands during the 1942-43 naval campaigns. March's warm water temperatures hover around 29°C (84°F), which means you are diving comfortably in a 3mm shorty or even just a rash guard on shallower wrecks. Visibility is variable during wet season, ranging from 10 metres (33 ft) on stirred-up days to a startling 30 metres (98 ft) when the current flushes clean water through the strait. The Bonegi I and Bonegi II wrecks, two Japanese transport ships sitting in 3 to 26 metres (10 to 85 ft) of water just west of Honiara, are accessible even when the outer sound is too rough, because they sit in the lee of Point Cruz. You will see lionfish drifting through blown-open cargo holds and hard coral encrusting gun mounts that have not moved since 1943. Mind you, March seas can turn quickly. Operators cancel outer-sound dives when swells exceed safe thresholds, so plan for at least one dive day being weathered out and you will not be disappointed.
The villages within an hour's drive of Honiara offer something that the resort islands of Fiji and Vanuatu have largely polished away: unscripted encounters with communities that still build leaf houses, carve war canoes, and prepare food in earth ovens called motu. At villages like Hotomai, east of the capital along the coast road, you will watch women weave pandanus mats on the packed-earth floor of an open-sided kitchen house while wood smoke curls through thatch above your head and children peer at you from behind breadfruit trees. March's rains make these visits more atmospheric, not less, the cooking fires burn hotter, the smell of roasting taro and coconut cream thickens in the humid air, and the community gathers closer under shelter. You will likely be offered kokoda, the Solomon Islands' version of ceviche: raw reef fish diced and marinated in fresh lime juice and coconut cream, served on a banana leaf, the flesh turned opaque-white and tasting of clean ocean tang with a fatty coconut finish. The etiquette matters: remove shoes before entering a family house, ask before photographing anyone, and accept what is offered to eat even if just a small taste. A gift of betel nut or stick tobacco is appreciated in many Guadalcanal villages and opens conversations faster than anything else.
The sheltered lagoons between Tulagi and the Florida Islands, about a 45-minute boat ride north of Honiara across Iron Bottom Sound, hold coral gardens that rival anything in Raja Ampat, and you will share them with nobody. The reef systems here drop from knee-deep shallows into walls that plunge 20 metres (66 ft) straight down, and March's warm 29°C (84°F) water keeps soft corals pulsing with color: deep purples, electric blues, the kind of fluorescent greens you associate with blacklight posters. Clownfish nest in anemones the size of dinner plates. Hawksbill turtles, unbothered by human presence because they so rarely encounter it, cruise the reef edge at arm's length. The trade-off is real, though: the crossing from Honiara can get rough when squalls move through, and some days the boat simply will not go. When the water is calm, it tends to stay calm until early afternoon, so morning departures are standard. Bring your own mask and snorkel if you are particular about fit, rental gear in the Solomons tends to be well-worn.
The Mataniko River cuts through limestone caves and dense secondary jungle on the southern outskirts of Honiara before dropping over a cascade into a gorge that the Japanese army used as a field hospital during the 1942 campaign. In March, the falls are at full volume, the roar fills the narrow canyon and the spray soaks you from 15 metres (49 ft) away. The trek to the falls takes roughly two hours each way from the trailhead in the Chinatown area of Honiara, crossing the river multiple times on slippery volcanic boulders. This is where March's conditions demand respect: water levels can rise fast after a heavy downpour upstream, turning ankle-deep crossings into waist-deep wading within thirty minutes. Go early, ideally before 8 AM, when the trail is cooler and afternoon thunderstorms have not yet loaded the river. The payoff is a swimming hole at the base of the falls where the water runs cool enough to cut through the heat, about 25°C (77°F) against the 30°C (86°F) air, and the jungle canopy overhead blocks enough sunlight that you can sit in the shallows without burning. You will hear parrots screaming from the ridge above and, if you are quiet, see kingfishers hunting the pools downstream.
