Top cities (4 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.

- ✕Tornado risk is real. Missouri is in tornado alley and both Kansas City and St. Louis metros have had damaging tornadoes. Joplin (2011) was devastating.
- ✕St. Louis has real public safety concerns in specific city neighborhoods. North St. Louis has high violent crime; Central West End, The Hill, Soulard, and Tower Grove are generally fine. Knowing neighborhoods matters.
