| January (high / low) | 22° / 9°C | 30° / 14°C |
| July (high / low) | 22° / 6°C | 31° / 24°C |
High-desert (2,335m) — 300+ sunny days a year, warm days, cold nights, almost no rain outside a brief Jan-Feb wet spell. One of the steadiest climates anywhere.
Tropical savanna in the northern hills — cool dry season Nov-Feb (the nomad high season), then the Feb-Apr burning-season haze, then monsoon.
Chiang Mai edges out Arequipa on the Mundevo composite, 6.2 to 6.0 out of 10 — a narrow 0.2-point margin across safety, healthcare, air quality and cost.
The composite gap is small enough that one weighted axis can flip the result. Use the per-axis breakdown below to see which city wins your specific priorities — someone optimizing for healthcare can land on a different answer than someone optimizing for affordability.
Run the salary calculator for both cities at your target lifestyle before deciding — Chiang Mai winning on quality doesn't mean the gross-salary requirement also lands in your favor. If you're on a balanced tier, the cost-of-living pages for each city carry the full monthly basket and the gross-salary figure.

Score-by-score, side-by-side
Each axis is scored independently with disclosed weights and a calculation string.
The exact scores and winners:
| Axis | Arequipa | Chiang Mai | Winner |
|---|---|---|---|
| Affordability | 7.7 | 7.4 | Arequipa +0.3 |
| Quality of life | 5.4 | 6.0 | Chiang Mai +0.6 |
| Remote-work friendliness | 5.4 | 6.7 | Chiang Mai +1.3 |
| Healthcare | 5.6 | 4.8 | Arequipa +0.8 |
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%)32
- Rent index (weight 40%)10
How this is calculated
Affordability = ((100 − costIndex)/100 × 0.6 + (100 − rentIndex)/100 × 0.4) × 10. For Arequipa: ((100 − 32)/100 × 0.6 + (100 − 10)/100 × 0.4) × 10 = 7.7.
Arequipa sits well below the New York baseline on both cost-of-living and rent. Budgets stretch further here than in benchmark Tier-1 cities.
Quality of life
- Safety index (weight 40%)45
- Healthcare index (weight 35%)55
- 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 Arequipa: (45/100 × 0.4 + 55/100 × 0.35 + 65/100 × 0.25) × 10 = 5.4.
Arequipa has a mixed quality profile. Safety: fair; healthcare: good; air: good. Weigh the weakest axis against your personal priorities.
Remote-work friendliness
- Internet (median Mbps) (weight 45%)70 Mbps
- Effective income tax (lower = better) (weight 30%)12.0%
- Cost-of-living (lower = better) (weight 25%)32
How this is calculated
RemoteWork = (min(Mbps/300, 1) × 0.45 + (1 − incomeTax) × 0.3 + (100 − costIndex)/100 × 0.25) × 10. For Arequipa: (min(70/300, 1) × 0.45 + (1 − 0.12) × 0.3 + (100 − 32)/100 × 0.25) × 10 = 5.4.
Arequipa works for remote work but isn't optimized for it: internet 70 Mbps, income tax 12%, cost index 32.
Healthcare
- Healthcare quality index (weight 70%)55
- Healthcare out-of-pocket / month (lower = better) (weight 30%)200
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Arequipa: (55/100 × 0.7 + max(0, 1 − 200/500) × 0.3) × 10 = 5.6.
Arequipa has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~200 PEN/month. Cross-border insurance closes the gap.

- Healthcare quality index (weight 70%)68
- Healthcare out-of-pocket / month (lower = better) (weight 30%)1200
How this is calculated
Healthcare = (qualityIndex/100 × 0.7 + max(0, 1 − OOP/500) × 0.3) × 10. For Chiang Mai: (68/100 × 0.7 + max(0, 1 − 1200/500) × 0.3) × 10 = 4.8.
Chiang Mai has trade-offs in healthcare: quality is good, typical out-of-pocket cost is ~1200 THB/month. Cross-border insurance closes the gap.
Monthly cost delta: Arequipa vs Chiang Mai
Normalized to PEN at 1 THB = 0.1039 PEN.
| Category | Arequipa | Chiang Mai | Change |
|---|---|---|---|
| housing | PEN 1,100 | THB 11,000 | +4% |
| food | PEN 700 | THB 6,500 | -4% |
| transport | PEN 100 | THB 800 | -17% |
| utilities | PEN 240 | THB 2,000 | -13% |
| leisure | PEN 600 | THB 7,500 | +30% |
| healthcare | PEN 200 | THB 1,200 | -38% |
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: Chiang Mai spends 5.5 percentage points more of its budget on it (26% vs. 20%). If you're sensitive to that category, weight the per-axis scores accordingly.

Salary equivalence: Arequipa ↔ Chiang Mai
What earning the same purchasing power costs in each city. Cost-adjusted using the local cost-of-living index (Arequipa = 32, Chiang Mai = 35); currency-converted at 1 THB = 0.1039 PEN. Tax differences are not modeled.
| Arequipa gross | Chiang Mai equivalent |
|---|---|
| PEN 40,000 | THB 421,094 |
| PEN 75,000 | THB 789,551 |
| PEN 120,000 | THB 1,263,281 |
| Chiang Mai gross | Arequipa equivalent |
|---|---|
| THB 40,000 | PEN 3,800 |
| THB 75,000 | PEN 7,124 |
| THB 120,000 | PEN 11,399 |
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: Arequipa vs Chiang Mai
Arequipa (America/Lima) and Chiang Mai (Asia/Bangkok) sit 12 hours apart in standard time. A 9-to-5 in one overlaps the other's for 0 hours a day — fully asynchronous collaboration.
Official: Spanish · English: Limited · Local language: Required
Spanish required — smaller expat infrastructure than Lima. English is confined to tourism around the historic center.
Official: Thai · English: Moderate · Local language: Helpful
The nomad/expat economy makes English moderately usable in Nimman and the old city; Thai is needed for admin and endears you everywhere. Northern Thai (Kham Mueang) is the local flavor.

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: 2026-06-10 (Arequipa) and 2026-06-10 (Chiang Mai).
- FX rate. 1 THB = 0.1039 PEN, 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
Data as of . Last reviewed .
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 Arequipa 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.
