The one-hour difference between winter and summer comes from daylight saving time in the UK and the US; local time in Martinique does not change.

Time difference and jet lag: practical tips

Flying to Martinique from Europe means travelling west: your day is lengthened and you will go to bed later than usual. From the US East Coast the gap is 1 hour in winter and no difference in summer, so time-zone jet lag is slight. A few simple rules help you adjust to local time:

  • 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 Martinique

  • Outbound from the UK (flying west): you « gain » 4 hours in UK winter and 5 hours in summer; your arrival day is lengthened and tiredness comes early in the local evening.
  • Return to the UK (flying east): the opposite applies. Flying east shortens the day: plan a quiet day when you get home.
  • Your usual night at home (23:00 – 07:00) corresponds to 19:00 – 03:00 in Fort-de-France from London in UK winter (18:00 – 02:00 during BST), and to 00:00 – 08:00 from New York during EST (23:00 – 07:00 during EDT): this is when your body will want to sleep for the first few days.
  • Daylight on arrival: in Fort-de-France, the sun rises around 06:33 and sets around 17:54 in mid-January, and around 05:43 and 18:38 in mid-July (table above). After flying west, make the most of the late-afternoon light to stay up until the evening; this is the standard advice for shifting your body clock.
