Things to Do in Solomon Islands in March
March weather, activities, events & insider tips
March Weather in Solomon Islands
Is March Right for You?
Advantages
- March sits right in the wet season sweet spot - you get afternoon downpours that clear the air and cool things down, but mornings are typically brilliant for diving and snorkeling when visibility hits 25-30 m (82-98 ft) underwater before any stirred-up sediment from rain affects it
- The rain brings Solomon Islands to life in ways the dry season just doesn't match - waterfalls around Guadalcanal are actually flowing with force, the jungle is impossibly green, and freshwater swimming holes like Mataniko Falls are at their best rather than reduced to trickles
- Tourist numbers drop significantly in March compared to July-August peak season, meaning you'll have dive sites like the Bonegi wrecks largely to yourself, accommodation prices run 20-30% lower than high season, and local guides have more availability for personalized experiences
- March timing works perfectly for WWII history enthusiasts - the humid conditions are actually closer to what soldiers experienced during the Guadalcanal Campaign, giving you a more authentic sense of the Pacific Theater environment when visiting battlefields and memorials
Considerations
- Those 10 rainy days mean you need genuine flexibility in your itinerary - if you've got a non-refundable boat charter to Marovo Lagoon and a storm system settles in, you might be stuck in Honiara for 2-3 days waiting for seas to calm from 2 m (6.5 ft) swells down to safe passage conditions
- Domestic flight schedules get disrupted more frequently in March - Solomon Airlines operates smaller aircraft that can't always land in heavy rain at outer island airstrips, and you'll want to build in at least one buffer day before any international departure to avoid missing connections
- The humidity at 70% combined with temperatures around 30°C (86°F) is genuinely challenging if you're not accustomed to tropical climates - you'll be sweating through clothes within 20 minutes of any activity, and things like cameras, electronics, and even cash can develop moisture issues without proper waterproof storage
Best Activities in March
WWII Wreck Diving and Snorkeling
March offers some of the year's best underwater visibility before the heavier rains of April-May, with morning dives typically giving you 20-30 m (65-98 ft) visibility around iconic sites. The water temperature sits at a comfortable 28-29°C (82-84°F), meaning you can get by with a 3mm wetsuit or even a rashguard for multiple dives. The Bonegi I and II wrecks off Honiara are accessible right from shore, while the deeper sites around Tulagi and Florida Islands see almost no other divers this time of year. Book morning departures specifically - afternoon rain doesn't usually affect underwater conditions but can make surface intervals on boats less pleasant.
Marovo Lagoon Village Stays
The world's largest double-barrier lagoon is actually more interesting in March than the dry season - the rain keeps everything lush, and you'll see locals actively working in their gardens and fishing during the productive wet season rather than the slower dry months. The lagoon stays calm enough for kayaking and swimming most days, though you'll want to plan water activities for mornings. Village guesthouses offer the most authentic Solomon Islands experience, where you're staying with families, eating what they eat, and learning traditional fishing techniques. The cultural exchange is genuine here, not performed for tourists.
Honiara Central Market and Local Food Experiences
March is actually peak season for tropical produce - you'll find everything from fresh coconuts and pawpaw to local greens like slippery cabbage and cassava at Honiara Central Market. The market runs every day but Saturday and Sunday mornings from 0530-1100 are when it's most alive, before the midday heat and afternoon rain send everyone home. This is where you'll see real Solomon Islands life - women selling betel nut, fishermen bringing in the morning catch, and the kind of cultural exchange that doesn't happen at resorts. Bring small bills in Solomon dollars, try the coconut bread from the bakery stalls, and don't be shy about asking what things are.
Guadalcanal Battlefield and Memorial Tours
March weather actually adds authenticity to WWII site visits - the heat, humidity, and sudden rain squalls give you a genuine sense of what soldiers dealt with during the 1942-43 campaign. Key sites like Bloody Ridge, Henderson Field, and the American Memorial are spread across several hours of driving, so you'll want a full day. The jungle has reclaimed most battlefields, but you'll still find rusted equipment, shell casings, and the occasional unexploded ordnance markers. Local guides who had family involved in the conflict provide context you won't get from guidebooks.
Waterfalls and Freshwater Swimming
This is genuinely the best time for waterfall visits - Mataniko Falls, Tenaru Falls, and smaller cascades around Guadalcanal are flowing strong after months of wet season rain, unlike the disappointing trickles you might find in October-November. The water is cool and clear, perfect for swimming after humid jungle walks. The 45-minute hike to Mataniko Falls involves river crossings that are actually easier in March when water levels are predictable, versus the flash flood risks of peak wet season in January-February. You'll likely have these spots to yourself on weekdays.
Traditional Fishing and Canoe Experiences
March sits in the productive fishing season when locals are actively working rather than just demonstrating for tourists. You can arrange to go out with fishermen in traditional outrigger canoes at dawn, learning techniques like handline fishing and net casting that haven't changed much in centuries. The experience is real work, not a sanitized tour - you'll be up at 0500, paddling for an hour, and actually helping bring in catch that feeds families. Some villages around Florida Islands and Savo Island offer these experiences, though you'll need to arrange through guesthouses rather than formal tour operators.
March Events & Festivals
Local Church Celebrations and Feasts
March doesn't have major national festivals, but Sunday church services followed by community feasts happen across the islands and offer genuine cultural immersion if you're respectful. Villages are predominantly Christian, and Sunday gatherings involve hours of singing, traditional dress, and shared meals afterward. If you're staying in a village guesthouse, you'll likely be invited to participate. This isn't a tourist event - it's real community life, and the welcome is genuinely warm if you show appropriate respect.
