Top cities (2 tracked)
Top drawbacks
- ✕Summer heat is genuinely extreme. 110°F+ days are common June-September, and 2023 saw Phoenix hit 119°F. Outdoor life basically stops — you exercise at 5am or not at all.
- ✕Electricity bills in summer are shocking — AC running 24/7 can push monthly bills to $400-$600 in detached homes. New builds with better insulation help.
- ✕Water security is a long-term question mark. Colorado River allocations are being reduced, and the state has groundwater commitments exceeding sustainable withdrawal. Urban water supply is fine now; long-term planning is uncertain.
South Carolina (SC)

Top cities (1 tracked)
Top drawbacks
- ✕Hurricane/flood risk is real in the Lowcountry — Katrina, Matthew, Florence, Ian all caused significant damage. "Sunny day flooding" in Charleston happens 3-5 times/year now (king tide + sea level rise), closing streets and roads with no storm.
- ✕Extreme summer heat and humidity — July-August regularly hit 92°F+ with 75%+ humidity, making outdoor activity miserable. Heat index routinely 100°F+. This is worse than Alabama due to coastal moisture.
- ✕Insurance costs are spiking coastal — homeowners insurance increased 15-25%+ annually in Charleston area. Flood insurance is separate and expensive. Some insurers are exiting the state entirely.
