Here's the true answer. I've lived at least three years each in both Florida and southern California.
They are totally different in some ways and similar in others.
Florida is hot, humid, and full of bugs. They get regular thunderstorms with towering cumulus clouds rolling in off the ocean or Gulf. The wilds of Florida are jungles filled with crocs, snakes, and other pleasant creatures. Hurricanes are the major nemesis in Florida. Immigrants pour in from Cuba.
Southern California has two major climates:
On the coast line, it's cool, humid (fog), and without bugs.
Inland, it's hot, dry, and without bugs.
The wilds of California are semi-arid desert, filled with cacti, brush, and very little wildlife compared to Florida. Earthquakes and wildfires are the major threats in California. By comparison, prices in California are way higher than for comparable items in Florida. Immigrants pour in from Mexico.
Both are heavily populated by Latinos, there are areas of LA and Miami where Spanish is the primary language. Both are overcrowded with people and cars (traffic), but LA and San Diego are the worst.
