October Weather in Solomon Islands
Is October Right for You?
Advantages
- October marks the beginning of the northwest monsoon with spectacular lightning displays over the islands - perfect for dramatic photography and fewer crowds at popular dive sites
- Sea temperatures reach optimal 28-29°C (82-84°F) with excellent visibility up to 30m (98 ft) before seasonal plankton blooms begin
- Traditional Melanesian festivals celebrate yam harvests across provinces, offering authentic cultural experiences without tourist crowds
- Flight prices from Australia and New Zealand drop 25-30% compared to dry season peaks as October is considered shoulder season
Considerations
- Afternoon thunderstorms become frequent (60% of days) lasting 1-2 hours, often disrupting boat transfers between 2-5pm
- Some remote outer islands become inaccessible due to rough seas, limiting options for multi-island hopping
- High humidity (85%) makes midday activities uncomfortable - you'll need to plan around weather patterns more carefully
Best Activities in October
World War II Historical Site Tours
October's cooler mornings (24-26°C/75-79°F) are perfect for exploring Guadalcanal battlefields and wreck sites. Rain rarely affects these tours as most sites have shelter, and the dramatic skies add atmosphere to historical photography. Local guides have more availability during shoulder season.
Traditional Village Cultural Experiences
October coincides with yam harvest season when villages celebrate with traditional feasts and custom dancing. The beginning of the wet season means lush green landscapes for village visits, and morning ceremonies avoid afternoon rain patterns.
Diving and Snorkeling Adventures
October offers the best diving conditions before November's plankton blooms reduce visibility. Water temperature peaks at 28-29°C (82-84°F), and morning dives (7am-11am) avoid afternoon weather. Coral spawning events may occur late October.
Bonegi Beach and Coastal Activities
October's high tides and warm water make beach activities ideal before the wet season intensifies. Morning beach time (6am-11am) offers calm conditions for swimming and snorkeling among WWII aircraft wrecks just offshore.
Marovo Lagoon Island Hopping
The world's largest saltwater lagoon offers protected waters even when outer reefs become rough in October. Traditional leaf house accommodations and pristine snorkeling in calm lagoon conditions make this ideal for multi-day exploration.
