Six months is not long to stay in Fiji unless you stay in a marina or
on the hard.
November to March is fantastic
fishing,
diving & sailing
weather in the north & west of Fiji.
Relentless
trade winds are gone with breeze from all directions every few or 4 days.
North can be wet but the West is dry away from Viti Levu.
Suva is humid.
Supply and services are the best in the region - excluding Aus & NZ.
Living is
cheap if you partially emulate the locals.
Cruising is varied with some great
anchorages off resorts, villages and
remote islands.
Much of the cruising is in smooth or partially smooth
water.
Cyclones are random and can occur any time even outside the designated season. I sat out a near miss in Pago Pago in May.
The early warning system is good and usually the developing system moves slowly (at first) so plenty of time to get out of the way.
Next
destination is not so far - Port Villa 500 nm. Honiara another 500 from Santo then New Brittan anotheer 500 ish.
New Caledonia is 250 from Villa.
Even NZ is reachable on a northerly in 4-6 days and by day 3 you would be out of reach of any but the fastest moving system (e.g. Sue 1999 25kts )
