Fiji Jet Lag Calculator

One useful constant: Suva — and with it the Fiji clock — stays pinned to UTC+12 for the whole trip. Two Fiji specifics compound the shift: Suva sits at 19 m (altitude makes poor sleep feel worse), and Oceania sits on the Oceania travel circuit most Fiji itineraries follow.

The size of your Fiji jet lag is the absolute gap between your home offset and Suva's UTC+12. Reference frame for Fiji: Suva keeps UTC+12 and sits 19 m above sea level in Oceania, with that same offset in every season.

Move 30–60 minutes daily toward Suva time (UTC+12) for 3–4 days pre-flight. Keep the Fiji flight alcohol-free. Treat the cabin as a preview of Fiji time rather than home time.

Dry cabin air quietly drains you on the way to Fiji; an extra 500 ml of water per 3 hours in the air keeps the Suva arrival day survivable. Morning light is the strongest reset signal Fiji offers at this shift size. In Suva (UTC+12), get it outdoors before 10am local.

Applied to this Oceania trip: 12 hours east from London to Suva maps to about 12 reset days, so a Fiji itinerary should front-load outdoor time on days one to 12.

A 10-minute warm shower an hour before bed speeds the core-temperature drop that starts sleep — a real head-start on the first jangled Fiji nights in Suva. Cap naps at 20–30 minutes and finish them by 3pm Suva time (UTC+12); anything longer steals the night that actually resets your clock to Fiji.

The Fiji sleep kit for Suva at 19 m: an eye mask, earplugs, curtains closed against the early sunrise, and a room held near 16–20°C. Practical baseline: lights out in a dark 16–20°C Suva room (19 m, UTC+12), and no evening alcohol for the first two nights while the Fiji clock settles.
