Is September Right for You?
Weigh the advantages and considerations before booking
Advantages
- + September lands in that narrow window between dry and wet, seven mornings out of ten open cobalt, then a squall barrels through, dumps its load, and vanishes within half an hour. The sky rinses clean and the sunset turns theatrical, good for drama-soaked photography.
- + Hotels slash rates by 25-30% from August highs. Yet the sea stays gin-clear for divers. Visibility at Mbonege Beach holds at 25 m (82 ft) for the entire month.
- + With local kids back at school, the beaches near Gizo and Munda empty out. On a 2 km (1.2 miles) crescent of white sand you may share the view with only two or three fishermen patching nets.
- + The bonito run kicks off mid-month. Fishing charters hook yellowfin tuna and wahoo within fifteen minutes of leaving port, and crews are happy to teach the old two-handed line-cast.
Considerations
- − Thunderstorms punch in around 2 PM. A flawless beach morning can flip into horizontal rain in twenty minutes, forcing you to abort boat trips halfway to the reef.
- − Several outer-island homestays shut in September while families head back to mainland gardens for sweet-potato planting. Your first-choice bed on a tiny island may simply be locked up.
- − The humidity punches above its weight, 70% air and 30°C (86°F) highs will have you swapping shirts twice a day unless you already live in the tropics.
Best Activities in September
Top things to do during your visit
WWII Wreck Diving Tours
September delivers the year's clearest water: 30 m (98 ft) of visibility above the intact Japanese transports off Bonegi Beach. You'll fin through cargo holds where sake bottles and medical kits lie exactly where they went down in 1942, while coral-draped machine guns still point toward the surface light.
Booking Tip: Reserve 7-10 days ahead with Honiara-based operators (see current tours in booking section below). Fewer divers in September mean longer bottom times and groups small enough to fit in one skiff.
Village Homestay Cultural Experiences
Harvest is over, so families have spare hours to teach pandanus weaving and shell-money making. Afternoons pass twisting coconut fibre into fishing line while kids crack sea almonds against coral heads, ending with torch-lit walks to the mangroves where they spear mud crabs by flashlight.
Booking Tip: Set things up through provincial tourism offices, not the internet. September availability shifts daily as families decide whether to stay put or sail off to church conferences.
Marovo Lagoon Kayaking Expeditions
The lagoon's 700 km² (270 sq miles) of protected water lies glass-flat on September mornings, good for paddling between double barrier reefs. You'll glide above coral gardens 2 m (6.5 ft) under your hull, then step onto sand cays where hermit crabs outnumber footprints ten to one.
Booking Tip: Multi-day paddling demands permits from the lagoon's tribal council. Arrange them two weeks ahead and carry small notes for village landing fees.
Skull Island Cultural Tours
September's lighter humidity makes the 45-minute jungle hike to the ancestral shrines tolerable. The trail cuts through old headhunting villages where weathered skull racks still stand in clearings. Guides recount how missionaries in canoes put an end to the practice in 1906.
Booking Tip: Entry hinges on permission from the chief's son, he handles tourism. Trips leave at 6 AM sharp to dodge midday heat and the afternoon storm cycle.
Tetepare Island Conservation Tours
The South Pacific's last undeveloped island shines brightest in September. Dawn patrols track nesting hawksbill turtles, snorkel sessions bring you face-to-face with bumphead parrotfish that no longer fear humans, and nights are spent in thatched eco-lodges lit only by bioluminescent plankton in the surf.
Booking Tip: The cap is twelve visitors per week, and September fills early. Secure your space 3-4 weeks ahead through the conservation association.

What's happening during your visit
Late September
Shell Money Festival
Traditional chiefs from Malaita converge on Auki to demonstrate the ancient currency system. Women string thumbnail shells into coils that once bought ocean-going canoes. Each bracelet takes three full days. The rhythmic click of shell on shell sounds like rain drumming on a tin roof.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
September is when island time stops pretending. Boat schedules hinge on a 6 AM radio weather report, so your 9 AM departure may slide to 11 AM, or tomorrow.
The finest seafood appears on church nights (Wednesday and Saturday) when fishing families cook the day's catch before Sunday worship. Look for smoke curling from back gardens around 5 PM.
Exchange rates jump 15% in your favour if you arrive with Australian dollars. Solomon Islands banks hold AUD reserves for Australian mining crews.
Phone signal vanishes 15 km (9.3 miles) beyond provincial capitals. Download offline maps before you leave town, and tell your lodge when to send the search party.
Avoid These Mistakes
Avoid tight connections through Honiara. Domestic flights often sit on the tarmac an extra 2-3 hours for weather, and boats won't wait, after 3 PM the afternoon storms make navigation dangerous.
Don't assume September equals dry season. Locals call it 'false dry' because warm water spawns storms fast. That 30% rain chance feels like 100% when you're stranded on a sandbar.
Slather on reef-safe sunscreen in villages and the zinc oxide will paint white war-paint stripes across your cheeks, great for shielding skin, lousy for photos meant to spark friendship rather than look like you're suiting up for battle.
