Prague vs Ostrava
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Prague leads on any axis where its bar is higher, Ostrava where its is. The cost bar uses a higher-is-cheaper scale, so Ostrava's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Prague | Ostrava |
|---|---|---|
| Livability | 64 | 65 |
| Cost (higher=cheaper) | 44 | 48 |
| Climate | 86 | 83 |
| Safety | 64 | 66 |
| Summer °C | 18.7 | 17.8 |
| Winter °C | -0.4 | -1.8 |
| Top disaster risk | extreme cold / winter | extreme cold / winter |
Prague vs Ostrava: the short answer
Ostrava comes out ahead on overall livability (65/100), only marginally above Prague (64/100). The two cities diverge most on cost of living. On affordability Ostrava is the cheaper base — nearly identical prices on our cost index (Prague 44 vs Ostrava 48, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Prague runs warmer in summer (about 18.7°C peak vs 17.8°C in Ostrava), while winter lows sit near -0.4°C in Prague and -1.8°C in Ostrava. On natural-disaster exposure Ostrava is the safer choice (safety 66/100); the dominant modelled hazard is extreme cold / winter for Prague and extreme cold / winter for Ostrava.
Which city should you choose?
- On a tight budget → Ostrava — lower everyday costs..
- You want warmth → Prague — hotter summers.

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.
