Everyone loves sunshine. But sunshine is not free. In the world of real estate and cost of living, it operates as a literal tax.

The High Cost of 70 Degrees

San Diego is famously the city without a bad day. Temperatures reliably hover between 65°F and 75°F year-round. But that perfection is aggressively priced into every square foot of real estate.

The Weather Premium

When comparing mid-sized cities, every additional 30 days of sunshine correlates to a roughly 5-10% increase in baseline median rent. In extreme cases like San Diego, the "Sun Tax" makes it one of the most unaffordable cities in the country relative to local median wages.

Miami and Phoenix offer a different flavor of the Sun Tax. They are significantly hotter and deal with extreme summers, but they attract massive influxes of out-of-state money explicitly chasing the winter sun.

Over the last five years, both cities saw staggering rent increases, effectively closing the gap between the "affordable sun belt" and the expensive coasts.

The takeaway is brutal but simple: if a city rarely requires you to wear a heavy coat, you will pay for that privilege every month in rent.
