Los Angeles to Miami: Route overview
This medium-haul route from Los Angeles (LAX) to Miami (MIA) covers 3,763 km in approximately 4h 56m to 5h 39m, crossing 3 time zones eastbound. The 3-hour eastbound shift means your body clock will be noticeably out of sync for 2–3 days, affecting sleep quality, appetite, and concentration at your destination. The route passes through North America's airspace, with flight paths that may vary by season due to weather patterns along the corridor.
What makes the Los Angeles–Miami route different
The specific combination of 3,763 km distance, 3-hour time difference, and eastbound direction places this route in the moderate jet lag category. Compared to a same-distance route with fewer time zones crossed, the circadian challenge here is the dominant factor in post-arrival recovery.
Arrival strategy for Miami
Arriving in Miami after a 3-hour eastward shift, your body will think it is 3 hours earlier than the local clock shows. If you arrive in the morning, push through fatigue and get outside in bright daylight. If you arrive in the evening, eat a light meal and go to bed at the local time — you may wake early, but resist getting up until at least 05:00.
Circadian rhythm analysis: Los Angeles → Miami
When you arrive in Miami, your circadian rhythm is still running on Los Angeles time. At 09:00 Miami time, your body clock reads 06:00 — early morning on your body clock. You will feel groggy but functional, with energy building through the local morning. By 22:00 local time (when you should sleep), your body reads 19:00 — approaching your natural evening. Sleep onset should be achievable with proper wind-down routine. Your circadian system adjusts at roughly 1 hour per day, so expect 3 days for full alignment.
Your body clock in Miami (day 1)
How your body clock maps to local time upon arrival, before any adjustment.
| Miami Time | Your Body Clock (Los Angeles) | How You Feel | Recommendation |
|---|---|---|---|
| 06:00 | 03:00 | Deep sleep phase. Intense drowsiness likely. | If awake, use bright light to push clock forward. Avoid driving or complex tasks. |
| 09:00 | 06:00 | Early wake phase. Groggy, low energy. | Light physical activity helps. Coffee is acceptable if 8+ hours before target bedtime. |
| 12:00 | 09:00 | Morning alertness building. Moderate energy. | Good window for bright light exposure if adjusting eastward. |
| 15:00 | 12:00 | Peak morning alertness on body time. | Productive window. Use this energy for important tasks. |
| 18:00 | 15:00 | Post-lunch dip. Moderate energy. | Brief 20-min nap acceptable if severely fatigued. Avoid long naps. |
| 21:00 | 18:00 | Afternoon alertness on body time. | Good window for light exposure if adjusting westward. |
| 00:00 | 21:00 | Evening wind-down. Melatonin starting to rise. | Dim lights and avoid screens if you need to stay awake longer. |
| 03:00 | 00:00 | Deep sleep phase. Intense drowsiness likely. | If awake, use bright light to push clock forward. Avoid driving or complex tasks. |
Pre-departure preparation
To prepare for this 3-hour eastward shift to Miami, begin adjusting 3 days before departure. Each night, move your bedtime 60 minutes earlier and wake correspondingly earlier. Seek bright light immediately upon waking. On departure day, set your watch to Miami time and begin eating meals on that schedule. This pre-adjustment can reduce your recovery time by 1–2 days.
Your first 72 hours in Miami
Day 1 in Miami: Your body is ~3 hours off local time. Get bright sunlight in the morning. Avoid napping past 14:00. Eat at local mealtimes even if not hungry. Caffeine is fine before 14:00, not after. Day 2: ~2 hours off. Continue morning (07:00–10:00) light exposure. Sleep quality should improve. Day 3: ~1 hours off. You should feel mostly adjusted. Return to normal activities.
Recovery timeline
Full circadian adjustment for the Los Angeles → Miami route typically takes 3 days, based on the body's natural adaptation rate of ~1 hour per day for eastbound travel.

By day 3, most travelers report feeling fully synchronized with Miami's schedule.

Miami at 26°N experiences moderate seasonal daylight variation. Summer offers longer evenings useful for westward adjustment, while winter's earlier sunsets support eastward adjustment schedules.
How the Los Angeles–Miami flight time is estimated
The 4h 56m to 5h 39m estimate for Los Angeles to Miami is derived from the 3,763-km great-circle distance. Medium-haul flights balance cruise and non-cruise phases, achieving effective speeds of 780–850 km/h. An additional 30–50 minutes accounts for taxi, takeoff, climb, descent, approach, and taxi at both LAX and MIA. Actual routing through controlled airspace may add 3–8% distance beyond the great-circle path due to air traffic corridors and restricted zones along the way.
Wind patterns and flight duration
Prevailing winds along the Los Angeles–Miami corridor have a moderate effect on flight time. The general west-to-east flow of upper-level winds at these latitudes provides a slight tailwind advantage.
Practical travel context
This medium-haul route connects Los Angeles (United States) with Miami (United States). Most travelers on stays of 3 days or longer will benefit from fully adjusting to Miami's local time, as the 3-hour shift is manageable within the first 2–3 days with proper light and sleep management.
