Ljubljana vs Koper
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Ljubljana leads on any axis where its bar is higher, Koper where its is. The cost bar uses a higher-is-cheaper scale, so Koper's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Ljubljana | Koper |
|---|---|---|
| Livability | 65 | 70 |
| Cost (higher=cheaper) | 48 | 53 |
| Climate | 85 | 96 |
| Safety | 66 | 64 |
| Summer °C | 18.1 | 22.3 |
| Winter °C | -1.0 | 4.2 |
| Top disaster risk | extreme cold / winter | earthquake |
Ljubljana vs Koper: the short answer
Koper comes out ahead on overall livability (70/100), modestly above Ljubljana (65/100). The two cities diverge most on climate. On affordability Koper is the cheaper base — nearly identical prices on our cost index (Ljubljana 48 vs Koper 53, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Koper runs warmer in summer (about 22.3°C peak vs 18.1°C in Ljubljana), while winter lows sit near -1.0°C in Ljubljana and 4.2°C in Koper. On natural-disaster exposure Ljubljana is the safer choice (safety 66/100); the dominant modelled hazard is extreme cold / winter for Ljubljana and earthquake for Koper.
Which city should you choose?
- On a tight budget → Koper — lower everyday costs..
- You want warmth → Koper — hotter summers.
- Safety is the priority → Ljubljana — lower disaster risk.

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.
