Oslo vs Trondheim
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Oslo leads on any axis where its bar is higher, Trondheim where its is. The cost bar uses a higher-is-cheaper scale, so Trondheim's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Oslo | Trondheim |
|---|---|---|
| Livability | 63 | 65 |
| Cost (higher=cheaper) | 45 | 48 |
| Climate | 80 | 78 |
| Safety | 66 | 70 |
| Summer °C | 16.4 | 13.6 |
| Winter °C | -3.2 | -2.7 |
| Top disaster risk | extreme cold / winter | extreme cold / winter |
Oslo vs Trondheim: the short answer
Trondheim comes out ahead on overall livability (65/100), only marginally above Oslo (63/100). The two cities diverge most on natural-disaster exposure. On affordability Trondheim is the cheaper base — nearly identical prices on our cost index (Oslo 45 vs Trondheim 48, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Oslo runs warmer in summer (about 16.4°C peak vs 13.6°C in Trondheim), while winter lows sit near -3.2°C in Oslo and -2.7°C in Trondheim. On natural-disaster exposure Trondheim is the safer choice (safety 70/100); the dominant modelled hazard is extreme cold / winter for Oslo and extreme cold / winter for Trondheim.
Which city should you choose?
- On a tight budget → Trondheim — lower everyday costs..
- You want warmth → Oslo — hotter summers.
- Safety is the priority → Trondheim — lower disaster risk.
- Best all-rounder → Trondheim — 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.
FAQ

What is the main natural-disaster risk in Oslo?
extreme cold / winter is the dominant modelled hazard for Oslo on our risk index.
How is the Oslo vs Trondheim comparison calculated?
Cost comes from World Bank price levels, climate from 1991–2020 normals, and disaster risk from USGS earthquake data, cyclone-basin position and flood exposure; livability is their weighted composite.
