Distance
How far is Lyon from Seoul?
Lyon is about 9,100 km (5,650 mi) from Seoul in a straight line — roughly 11 h 25 m of nonstop flight time.
Great-circle distance, not a routed itinerary; flight estimate assumes ~850 km/h cruise plus 45 minutes of taxi, climb and descent.
Climate
Is Lyon warmer than Seoul?
Lyon is the warmer city: January highs average 7°C vs 2°C, and July 28°C vs 29°C. Annual sunshine is comparable between the two.
| Month | Lyon | Seoul |
|---|---|---|
| January (high / low) | 7° / 1°C | 2° / -6°C |
| July (high / low) | 28° / 17°C | 29° / 22°C |
Semi-continental with Mediterranean influence. Warmer than Paris, four distinct seasons, sunnier than most French northern cities.
Continental with monsoonal summers. Cold dry winters, hot humid wet summers, distinct rainy season in July. Yellow-dust events in spring.
Lyon edges Seoul by just 0.4 points despite Seoul's 10 million residents, suggesting quality-of-life factors matter more than sheer scale in city livability.
Seoul typically dominates rankings on economic dynamism and infrastructure, making Lyon's narrow lead unusual and worth examining.
Dig into what Lyon does differently on housing affordability, cultural access, or work-life balance—these quiet strengths often get overlooked in mega-city comparisons.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Lyon | Seoul | Winner |
|---|---|---|---|
| Affordability | 3.2 | 3.1 | Lyon +0.1 |
| Quality of life | 6.8 | 7.6 | Seoul +0.8 |
| Remote-work friendliness | 6.5 | 7.5 | Seoul +1.0 |
| Healthcare | 8.4 | 5.8 | Lyon +2.6 |
Each axis is a weighted aggregate of underlying indicators normalized to a 0–10 scale. Weights are explicit and disclosed per axis. The composite is the unweighted mean of the four axes — axes are not collapsed further because the underlying trade-offs (e.g. low cost vs poor air quality) are user-dependent.
Affordability
- Cost-of-living index (weight 60%)77
- Rent index (weight 40%)55
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Lyon: ((100 − 77)/100 × 0.6 + (100 − 55)/100 × 0.4) × 10 = 3.2.
Lyon is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)60
- Healthcare index (weight 35%)80
- Air quality index (weight 25%)65
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Lyon: (60/100 × 0.4 + 80/100 × 0.35 + 65/100 × 0.25) × 10 = 6.8.
Lyon has a mixed quality profile. Safety: good; healthcare: excellent; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)220 Mbps
- Effective income tax (lower = better) (weight 30%)14.0%
- Cost-of-living (lower = better) (weight 25%)77
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Lyon: (min(220/300, 1) × 0.45 + (1 − 0.14) × 0.3 + (100 − 77)/100 × 0.25) × 10 = 6.5.
Lyon works for remote work but isn't optimized for it: internet 220 Mbps, income tax 14%, cost index 77.
Healthcare
- Healthcare quality index (weight 70%)80
- Healthcare out-of-pocket / month (lower = better) (weight 30%)40
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Lyon: (80/100 × 0.7 + max(0, 1 − 40/500) × 0.3) × 10 = 8.4.
Lyon combines excellent system quality with a manageable out-of-pocket cost (~40 EUR/month). Travel insurance still recommended for non-residents.

Seoul is among the more expensive cities tracked. Salary expectations should be calibrated to the high cost base before relocating.
Quality of life
- Safety index (weight 40%)82
- Healthcare index (weight 35%)83
- Air quality index (weight 25%)55
How this is calculated
QoL = (safety/100 × 0.4 + healthcare/100 × 0.35 + airQuality/100 × 0.25) × 10. For Seoul: (82/100 × 0.4 + 83/100 × 0.35 + 55/100 × 0.25) × 10 = 7.6.
Seoul scores excellent on safety, excellent on healthcare and good on air. The composite quality-of-life signal is strong.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)280 Mbps
- Effective income tax (lower = better) (weight 30%)12.0%
- Cost-of-living (lower = better) (weight 25%)75
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Seoul: (min(280/300, 1) × 0.45 + (1 − 0.12) × 0.3 + (100 − 75)/100 × 0.25) × 10 = 7.5.
Seoul combines fast internet (280 Mbps median), a 12% effective income tax and cost index 75 — a strong configuration for remote workers earning in a stronger currency.
Healthcare
- Healthcare quality index (weight 70%)83
- Healthcare out-of-pocket / month (lower = better) (weight 30%)35000
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Seoul: (83/100 × 0.7 + max(0, 1 − 35000/500) × 0.3) × 10 = 5.8.
Seoul has trade-offs in healthcare: quality is excellent, typical out-of-pocket cost is ~35000 KRW/month. Cross-border insurance closes the gap.
Monthly cost delta: Lyon vs Seoul
Normalized to EUR at 1 KRW = 0.0007 EUR.
| Category | Lyon | Seoul | Change |
|---|---|---|---|
| housing | €1,000 | ₩1,100,000 | -26% |
| food | €400 | ₩450,000 | -24% |
| transport | €70 | ₩65,000 | -37% |
| utilities | €150 | ₩140,000 | -37% |
| leisure | €320 | ₩250,000 | -47% |
| healthcare | €40 | ₩35,000 | -41% |
Where each city's money goes
Two cities can have the same monthly total but very different shapes — one might burn 50% on housing while the other splits more evenly. The composition matters as much as the headline.
The biggest shape difference is leisure: Lyon spends 3.9 percentage points more of its budget on it (16% vs. 12%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Lyon ↔ Seoul
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Lyon = 77, Seoul = 75); currency-converted at 1 KRW = 0.0007 EUR. Tax differences are not modeled.

Equivalence here means same cost-of-living purchasing power, not same net take-home. Effective tax rates differ between countries; a salary equivalent on cost can still net more or less depending on the destination's tax regime. Use the calculator for tax-adjusted figures at a specific lifestyle tier.

Remote work logistics
Time zones and language: Lyon vs Seoul
Lyon (Europe/Paris) and Seoul (Asia/Seoul) sit 8 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration. Note: Lyon observes daylight saving while Seoul doesn't, so the gap shifts by an hour part of the year.
Official: French · English: Moderate · Local language: Recommended
French is required for daily-life bureaucracy and most workplaces. English usable in Part-Dieu business district and at international firms; limited elsewhere.
Official: Korean · English: Moderate · Local language: Useful
Korean is the daily-life default. English usable in expat-heavy neighborhoods (Itaewon, Hannam) and international firms; outside that, limited. Hangul is easy to learn even if speaking is slow.

How this page is calculated
Data sources
- Mundevo per-city dataset. Cost basket, rent index, safety, healthcare, air quality and median internet for both cities. Reference date: 2026-05-28 (Lyon) and 2026-05-28 (Seoul).
- FX rate. 1 KRW = 0.0007 EUR, used to normalize cost baskets.
- CityScoreCalculator. Four axes (Affordability, Quality of life, Remote work, Healthcare) computed with explicit weights and explanations. See per-axis calculation strings rendered on this page.
- ComparisonService. Per-category cost deltas (housing, food, transport, utilities, leisure, healthcare) normalized to the origin currency.
Update cadence

Calculation
For each of the four axes we compute an independent 0–10 score using the formulas printed beside each axis. The composite is the unweighted mean of the four axes. The overall winner is the city with the higher composite, unless the margin is under 0.05 points — in which case Lyon is shown first as a tiebreaker to keep results stable.
Limitations
- Climate is not scored — we don't yet hold a maintained climate dataset, so weather-driven preferences are not modeled.
- Tax differences between cities in the same country are not modeled (Spain and Germany don't have material regional differences for this dataset).
- Indices are population-level. Personal cost varies with neighborhood, employer benefits and family status.
- Quality-of-life axis weights (safety 0.4 / healthcare 0.35 / air 0.25) are editorial defaults — readers with strong preferences should re-weight manually.
