Colombo vs Jaffna
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. Colombo leads on any axis where its bar is higher, Jaffna where its is. The cost bar uses a higher-is-cheaper scale, so Jaffna's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | Colombo | Jaffna |
|---|---|---|
| Livability | 59 | 59 |
| Cost (higher=cheaper) | 46 | 49 |
| Climate | 78 | 69 |
| Safety | 55 | 61 |
| Summer °C | 28.4 | 30.2 |
| Winter °C | 26.7 | 25.6 |
| Top disaster risk | flooding | storms (hurricane/cyclone) |
Colombo vs Jaffna: the short answer
Jaffna comes out ahead on overall livability (59/100), only marginally above Colombo (59/100). The two cities diverge most on climate. On affordability Jaffna is the cheaper base — nearly identical prices on our cost index (Colombo 46 vs Jaffna 49, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Jaffna runs warmer in summer (about 30.2°C peak vs 28.4°C in Colombo), while winter lows sit near 26.7°C in Colombo and 25.6°C in Jaffna. On natural-disaster exposure Jaffna is the safer choice (safety 61/100); the dominant modelled hazard is flooding for Colombo and storms (hurricane/cyclone) for Jaffna.
Which city should you choose?
- On a tight budget → Jaffna — lower everyday costs..
- You want warmth → Jaffna — hotter summers.
- Safety is the priority → Jaffna — lower disaster risk.
- Best all-rounder → Jaffna — 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.
