San Diego vs Austin
How to read the comparison chart
The grouped bars score each city 0–100 on cost, climate and safety — taller is better. San Diego leads on any axis where its bar is higher, Austin where its is. The cost bar uses a higher-is-cheaper scale, so San Diego's taller cost bar reflects its lower cost of living, not a higher price.
| Axis | San Diego | Austin |

| Livability | 58 | 46 |
| Cost (higher=cheaper) | 15 | 0 |
| Climate | 100 | 76 |
| Safety | 65 | 65 |
| Summer °C | 22.5 | 28.9 |
| Winter °C | 13.9 | 9.3 |
| Top disaster risk | wildfire | storms (hurricane/cyclone) |
San Diego vs Austin: the short answer
San Diego comes out ahead on overall livability (58/100), clearly above Austin (46/100). The two cities diverge most on climate. On affordability San Diego is the cheaper base — a wide gap on our cost index (San Diego 15 vs Austin 0, where a higher score means a lower cost of living, normalised from World Bank price levels). For climate, Austin runs warmer in summer (about 28.9°C peak vs 22.5°C in San Diego), while winter lows sit near 13.9°C in San Diego and 9.3°C in Austin. On natural-disaster exposure Austin is the safer choice (safety 65/100); the dominant modelled hazard is wildfire for San Diego and storms (hurricane/cyclone) for Austin.

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.
