Solomon Islands in December: Weather, Crowds & What to Expect

Honiara & Guadalcanal Coast

December is hot and frequently wet, with abrupt squalls and afternoons that can feel close to oppressive as the wet season peaks. Festive season travel increases local movement and air seats sell out; the island’s shoreline can be rough during storms, so avoid planning delicate sea transfers around the Christmas holidays without contingency days. Waterproof bags, flexible bookings and a calm mindset help when rain-driven delays occur.

Central Province (Florida Islands, Tulagi, Russell Islands)

December is hot, humid and punctuated by heavy showers - freshwater supplies on small islands can be affected by saltwater splash during big weather, so check guesthouse provisions. The sheltered lagoons can offer calm diving windows, but expect more frequent cancellations and rougher approaches to smaller landings. Pack for heat, rain and the unpredictability of inter-island transport at the peak of the wet season.

Western Province (Gizo, New Georgia, Munda, Marovo Lagoon)

December becomes hot, humid and increasingly storm-prone, with heavy showers and occasional strong systems sweeping through the island groups. Holiday travel can swell local demand for limited flights and charters, and rough seas make some landings tricky; travel insurance and flexible plans are strongly advised. Waterproof provisions for camera gear and protective storage for dive equipment are essential during the wettest spells.

Malaita & Savo Coastal Areas

December is hot, humid and often rainy, with squalls that can dramatically change sea conditions and disrupt small-boat movements around Malaita and Savo. Festive season travel and village events may raise local activity, but travel logistics become less certain because of weather delays; keep flexible itineraries and waterproof storage for all gear.

Temotu & Santa Cruz Islands (Tikopia, Anuta, Vanikoro)

December is hot, increasingly damp, and punctuated by heavy tropical showers that can close small airstrips and make landings difficult on exposed beaches. Festivals or local events can occur, but logistics become precarious as the wet season progresses; if you must travel, allow multiple buffer days for sea and air transfers. Carry robust waterproofing and plan minimal assumptions about on-island services.

Rennell, Bellona & Makira-Ulawa (Southern islands)

December is hot and rainy with frequent tropical downpours that make some roads and paths difficult to use and can delay inter-island shipping. Lake Tegano and lowland tracks become very wet and buggy, so waterproof boots and repellent are essential for overland exploration. If traveling at this time, expect weather-driven schedule changes and carry flexible tickets and travel insurance.
