Diving in the Solomon Islands in March

Conditions in March

So, you're eyeing the Solomon Islands for a dive trip in March? Excellent choice! While March falls within the "wet season" here, don't let that deter you. Often, the wet season brings short, sharp tropical showers rather than prolonged downpours, and these usually occur in the late afternoon or overnight, leaving your dive days largely clear. The air temperature remains consistently warm, hovering around 28-32°C (82-90°F), perfect for liveaboard life between dives.

When it comes to the water, you're in for a treat with delightfully warm temperatures. Expect the water to be between 28-30°C (82-86°F), meaning even a thin 3mm wetsuit might be optional, or purely for comfort on multiple dives. Visibility is generally excellent throughout the Solomons, and March is no exception. You can typically expect a stunning 20-30 meters (65-100 feet) or more, offering crystal-clear views of the vibrant reefs and dramatic seascapes.

Regarding currents, the Solomon Islands are known for their healthy currents, which are key to their rich biodiversity. March is no different. You'll encounter mild to moderate currents on many dives, particularly around passes and exposed sites. These currents bring in nutrients, attracting pelagic life and keeping the corals thriving. Your experienced liveaboard crew will always brief you thoroughly on the expected conditions and ensure drift dives are executed safely and enjoyably.

What you will see

March in the Solomon Islands is prime time for an astonishing array of marine life. The warm, nutrient-rich waters support incredibly diverse ecosystems. Expect to be immersed in some of the healthiest reefs on the planet, teeming with hard and soft corals in every imaginable color and form. Reef fish are abundant, from swarms of fusiliers and anthias to inquisitive butterflyfish, angelfish, wrasse, and parrotfish. Keep your eyes peeled for the endemic species that make the Solomons so unique, such as the Solomon Islands Anemonefish, often found nestled in their host anemones.

Pelagic encounters are a frequent highlight. Shark sightings are common, with grey reef sharks, whitetip reef sharks, and blacktip reef sharks patrolling the outer reefs. If you're lucky, you might even spot hammerheads or silvertips, especially around deeper walls. March can also be a good month for manta rays, particularly in areas where cleaning stations are active. Keep an eye on the blue for schooling barracuda, trevally, and tuna. You might also spot eagle rays gracefully gliding past. The Solomons are also a special place for marine mammals; dolphins are often seen accompanying liveaboards, and while rarer, humpback whales can be observed migrating through these waters, though March isn't peak season for them.

For macro enthusiasts, March offers endless discoveries. The reefs are home to a phenomenal diversity of critters. Peer into crevices and beneath overhangs to find pygmy seahorses, various species of nudibranchs, flatworms, and ghost pipefish. Harlequin shrimp, often guarding their starfish prey, are another sought-after find. The intricate coral structures provide perfect habitats for countless small invertebrates, making every square meter of reef a treasure hunt for keen-eyed photographers. Given the excellent visibility, you'll have ample opportunity to capture stunning wide-angle and macro shots.

Top dive sites this month

For an unforgettable March dive experience, the Russell Islands are a must-visit. Specifically, sites like Mary Island (also known as Marovo Lagoon or simply "Barracuda Point") offer spectacular diving. Here, you can expect exhilarating drift dives along a wall, often accompanied by strong currents, bringing in large schools of barracuda, jacks, and various shark species. The vibrant hard coral gardens here are breathtaking. Another gem in the Russells is "The Leru Cut," a truly unique dive where you swim into a deep, narrow canyon that slices through an island, emerging into a crystal-clear freshwater pool deep inside. The light shafts are simply magical.

Moving further west, the waters around New Georgia are exceptional in March. Don't miss "Toa Maru" near Gizo, a Japanese transport ship sunk during WWII. This wreck is incredibly intact and teeming with marine life, adorned with corals. It's a fantastic penetration dive for experienced wreck enthusiasts. Also in the New Georgia group, the caves and caverns of "Kashi Maru" and "Grand Central Station" are phenomenal. Grand Central Station, an iconic wall dive, is a vortex of pelagic action, with sharks circling in the blue and large schools of fish. The sheer biodiversity of these sites makes them perennial favorites and especially vibrant in the consistent conditions of March.

Practical tips for your trip

Given the consistently warm water temperatures of 28-30°C (82-86°F) in March, a 3mm shorty wetsuit or even just a rash guard will usually suffice for thermal protection. However, if you tend to get cold easily or plan on doing multiple dives a day, a full 3mm suit offers good protection from coral scrapes too. This month typically suits all levels of divers. Beginners will find plenty of sheltered, shallower reefs to explore, while advanced divers will revel in the pelagic action and thrilling drift dives offered at more exposed sites.

Liveaboard availability in March can vary. While it's technically still the wet season, the Solomon Islands are a high-demand destination, so it's always wise to book your liveaboard well in advance to secure your preferred vessel and itinerary. What to pack? Light, breathable clothing is essential given the tropical climate. Definitely bring plenty of reef-safe sunscreen, a wide-brimmed hat, and insect repellent for evenings on deck or any land excursions. Don't forget your camera gear – you'll want to capture every moment of this incredible underwater paradise. Be aware that remote areas may have limited access to medical facilities, so ensure your travel insurance covers diving and medical evacuations. Lastly, embrace the relaxed, friendly pace of island life – "island time" is a real thing, and it's all part of the charm!
