San Diego costs about 8% more day to day, but Miami has no state income tax while California does — which can reverse the comparison once you look at take-home rather than sticker prices.
Housing does most of the damage
Housing is the reason two metros differ at all. Everything else — groceries, a haircut, a phone plan — varies far less than rent does. A one-bedroom runs about $2,400 a month in Miami and $2,400 in San Diego — $0 a month apart, or $0 a year.
If you plan to buy rather than rent, the numbers move further apart: median prices of $550,000 and $900,000 mean a difference of about $70,000 in up-front cash at 20% down, plus whatever the property tax spread between Florida and California adds annually.
The price-to-rent ratios diverge enough to change the buy-versus-rent answer: about 19 in Miami versus 31 in San Diego. Under about 15 the math favours owning; over about 20 it favours renting and putting the down payment to work elsewhere. Which means the right answer can genuinely be to buy in one and rent in the other.
Taxes the index leaves out
Income tax is the variable the index ignores, and here it is decisive: Florida charges none while California does. Budget $4,000–$8,000 a year of difference on a $100,000 salary before comparing rents.
The offset is rarely free, though. States without an income tax usually recover it elsewhere — property tax rates in Florida and sales tax are the usual places to look. If you plan to buy rather than rent, run the property tax number before assuming the no-income-tax state is cheaper.
Work, weather, and what else is different
Miami is a major metro of about 6.1M and growing fast; San Diego is a large metro of about 3.3M and growing steadily.
The two economies have little in common. Miami runs on international trade & finance, tourism/hospitality, real estate — University of Miami and Baptist Health South Florida among the larger employers — while San Diego runs on military/defense, biotech, tourism, with US Navy and Qualcomm. Moving between them usually means changing industry as well as address, so line up work first.
Climate belongs in the comparison, not as a footnote. Miami: Tropical climate: January lows near 62°F, July highs near 90°F with high humidity, active June-November hurricane season. San Diego: Mediterranean climate with mild winters near 50°F lows and mild summers with July highs near 76°F, rarely extreme in either direction.
No state income tax, but homeowners' insurance premiums are among the highest in the US due to hurricane and flood risk, often adding $4,000-$8,000+ a year to housing costs. Among the most expensive housing markets in the country despite no local income tax; mild year-round climate is a major draw offsetting high housing cost.
The index behind the headline ratio is BEA Regional Price Parity data; rents and home prices are market figures, and tax rates are as published by each state and city. How these are compiled and updated.
