Jet Lag from Los Angeles to Sydney

Sydney runs 17 hours ahead of Los Angeles — a westbound shift over a roughly 15-hour flight. Expect about 17 days to feel close to normal in Sydney.

What to expect

Westward shifts extend the day and align with the natural drift of the circadian rhythm, so most travelers find them easier than eastward shifts.

Adjustment playbook

  • Stay up later than usual the night before.
  • Stay awake on the plane during Sydney daytime.
  • Get bright late-afternoon light on arrival; avoid bright morning light day one.
  • Late-afternoon caffeine is fine.
