Flight time & jet lag: London to Moscow

London to Moscow: Route overview

This medium-haul European route links London with Moscow over 2,508 km, offering a quick 3h 27m to 4h 03m connection across 3 time zones. 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. Moscow's high latitude means extreme seasonal daylight variation — near-24-hour sunlight in summer and very short days in winter — which significantly impacts light-based jet lag strategies.

What makes the London–Moscow route different

The specific combination of 2,508 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 Moscow

Arriving in Moscow 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: London → Moscow

When you arrive in Moscow, your circadian rhythm is still running on London time. At 09:00 Moscow 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.

Pre-departure preparation

To prepare for this 3-hour eastward shift to Moscow, 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 Moscow 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 Moscow

Day 1 in Moscow: 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 London → Moscow route typically takes 3 days, based on the body's natural adaptation rate of ~1 hour per day for eastbound travel. During this period, expect gradually improving sleep quality, with the most noticeable symptoms (fatigue, difficulty concentrating, appetite changes) during the first 3 days. By day 3, most travelers report feeling fully synchronized with Moscow's schedule.

Seasonal and climate factors

Flight times between London and Moscow can vary by 15–30 minutes seasonally due to shifting wind patterns along this medium-haul corridor. Moscow's high latitude (56°N) means dramatic seasonal daylight swings — from near-continuous summer daylight to very short winter days. This directly affects light-based jet lag strategies: summer visitors may need blackout curtains, while winter arrivals should maximize limited daylight exposure.

How the London–Moscow flight time is estimated

The 3h 27m to 4h 03m estimate for London to Moscow is derived from the 2,508-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 LHR and SVO. 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 London–Moscow 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 intra-European route connects London (United Kingdom) with Moscow (Russia). Flights are typically operated by both full-service and low-cost carriers, with high frequency during business days. Most travelers on stays of 3 days or longer will benefit from fully adjusting to Moscow's local time, as the 3-hour shift is manageable within the first 2–3 days with proper light and sleep management.
