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
& sailing weather
in the north & west of Fiji.
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
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.
is not so far - Port Villa 500 nm. Honiara another 500 from Santo then New Brittan anotheer 500 ish.
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 )
