- Set your watch and phone to local time as soon as you board.
- Align meals and bedtime with local time from the first day.
- Plan a light first day, with no important meetings or long drives.
- Get out in daylight when you arrive and avoid long naps.
- If you take medication at fixed times, ask your doctor how to adapt the schedule to the time difference.

Jet lag: how flight direction affects you in New Caledonia
- Outbound from the UK (flying east): you « lose » 11 hours in UK winter and 10 hours in summer; your arrival day is shortened and you need to go to bed earlier than your body clock expects.
- Return to the UK (flying west): the opposite applies. Flying west is generally considered easier to cope with: you just need to stay up a little later.
- From New York: the gap is 16 hours in winter (EST) and 15 hours in summer (EDT); you cross the International Date Line and land on a later calendar day, so allow extra time to adjust.
- Your usual night at home (23:00 – 07:00) corresponds to 10:00 – 18:00 in Nouméa from London in UK winter (09:00 – 17:00 during BST), and to 15:00 – 23:00 in Nouméa from New York during EST (14:00 – 22:00 during EDT): this is when your body will want to sleep for the first few days.
- Daylight on arrival: in Nouméa, the sun rises around 05:23 and sets around 18:44 in mid-January, and around 06:34 and 17:27 in mid-July (table above). After flying east, seek morning light and avoid it late in the day; this is the standard advice for shifting your body clock.
