Seattle vs Rio de Janeiro
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Seattle leads on any axis where its bar is higher, Rio de Janeiro where its is. The cost bar uses a higher-is-cheaper scale, so Rio de Janeiro's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Seattle | Rio de Janeiro |
|---|---|---|
| Livability | 59 | 60 |
| Cost (higher=cheaper) | 19 | 43 |
| Climate | 97 | 90 |
| Safety | 66 | 51 |
| Summer °C | 18.6 | 26.0 |
| Winter °C | 4.5 | 20.3 |
| Top disaster risk | wildfire | flooding |
Seattle vs Rio de Janeiro: the short answer
Rio de Janeiro comes out ahead on overall livability (60/100), only marginally above Seattle (59/100). The two cities diverge most on cost of living. On affordability Rio de Janeiro is the cheaper base — a wide gap on our cost index (Seattle 19 vs Rio de Janeiro 43, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Rio de Janeiro runs warmer in summer (about 26.0°C peak vs 18.6°C in Seattle), while winter lows sit near 4.5°C in Seattle and 20.3°C in Rio de Janeiro. On natural-disaster exposure Seattle is the safer choice (safety 66/100); the dominant modelled hazard is wildfire for Seattle and flooding for Rio de Janeiro.
Which city should you choose?
- On a tight budget → Rio de Janeiro — lower everyday costs.
- You want warmth → Rio de Janeiro — hotter summers.
- Safety is the priority → Seattle — lower disaster risk.
- Best all-rounder → Rio de Janeiro — highest overall livability.
Data & methodology
Cost scores are normalised from World Bank price-level data. Climate figures (summer highs, winter lows) are drawn from 1991–2020 climate normals. Disaster-safety blends USGS earthquake history (magnitude 4.5+ within 300 km since 1980), tropical-cyclone basin position, flood/elevation exposure and Köppen climate zone. The livability score is the weighted composite of cost, climate and safety. All figures are planning indicators for 2026, not guarantees — verify specifics before relocating.
