Cyclone Buffer Picker

Fiji sits in the South Pacific cyclone basin, which is one of the smaller and less active cyclone basins on Earth — but the cyclones it does get tend to be intense. The official Fiji Met Service season is November to April, with about 8–10 named systems in any given year, of which roughly 2–3 reach Category 3+ and 0–1 reach Category 4 or 5. The 10-year climatology 2014–2024 has TC Winston (2016, Cat 5 — the most intense ever to make landfall in the Southern Hemisphere) as the outlier, plus a long tail of Cat 1–2 systems.

Month matters more than week. January, February and March are the peak — about 60% of all Cat 3+ systems form or pass through in these three months. November tends to have one early-season system pass. December and April are shoulder months with one system each, typically Cat 1–2. May through October is technically off-season — named cyclones in Fiji in June–October are rare (one or two in the entire 10-year record, and usually decaying systems drifting in from the south).

Island group matters less than you'd think. All the major groups sit within ~150 km of each other and a cyclone is rarely selective. The exception: the southern islands (Beqa, Kadavu, southern Viti Levu) tend to take the brunt of south-tracking systems, while Vanua Levu / Taveuni catches the north-tracking ones. The Mamanucas sit in the path of anything tracking through the central group.

Sensitivity is the dial you control. A city-only itinerary can shelter in a concrete hotel for 24–48 hours and emerge with the holiday mostly intact. A sailing itinerary can't — even a Cat 1 system 300 nautical miles away will put seas at 3–4 m and cancel everything. A diving itinerary sits in between: operators won't go out at Cat 1+ within 200 nm, but you can use the lay-days for inland activities.

• This is a climatological risk dial, not a forecast. A "low" October can still see a tropical low form. Always check the live Fiji Met Service TC outlook before flying.
• Named cyclone category ≠ impact. A slow-moving Cat 1 over Kadavu for 36 hours dumps more rain and causes more flooding than a fast Cat 3 that grazes the Yasawas.
• Storm surge is the biggest single fatality cause in Pacific cyclones. Coastal resorts on flat islands (Mamanuca, Yasawa) are more exposed than hill resorts (Pacific Harbour interior).
• Insurance cyclone rider terms vary. Some cover any named-system cancellation; others require a Cat 2+ within X km. Don't assume your policy covers what you think it covers.
• This tool doesn't predict cyclone landfall locations — the 10-year record shows they can hit anywhere from Rotuma to Kadavu.
• "Buffer days" is a planning heuristic, not a guarantee. If a Cat 3 is forecast 5 days out and your flight is in 2 days, the buffer doesn't help.
