What Is South Florida? The Counties, Cities, and Coastal Life
July 25, 2026 · 7 min read · By Pure Equity Realty
What is South Florida, really? Here is a plain guide to the counties, the three sub-regions, the lifestyle, and where to buy along the coast.
So what is South Florida? At its simplest, it is the southern third of the state, a warm and coastal stretch that runs from the Miami metro up the Atlantic shore to the Treasure Coast. People use the name loosely, and the exact borders shift depending on who you ask. Still, most residents mean a cluster of counties that share a climate, a beach-first lifestyle, and a fast-growing housing market. Here is how the region breaks down and what it means if you are thinking about moving here.
Key Takeaways
- South Florida usually means the counties along the state's southern Atlantic coast, anchored by Miami-Dade, Broward, and Palm Beach.
- The wider region also includes the Treasure Coast (Martin, St. Lucie, and Indian River) and interior counties like Highlands and Okeechobee.
- The area shares a subtropical climate, a coastal lifestyle, and no state income tax.
- Prices swing widely, from luxury barrier islands to affordable inland towns.
- Where you land depends on budget, commute, and whether you want beach, suburb, or country.
What is South Florida, exactly?
What is South Florida in geographic terms? It is the part of the peninsula below a rough line drawn near Lake Okeechobee, where the climate turns fully subtropical and the coast becomes one long chain of beach towns. Unlike Central or North Florida, this stretch rarely sees frost, and the ocean shapes daily life. The name is cultural as much as it is geographic, since the region shares its own pace, food, and mix of people.
Because the term is informal, its edges are fuzzy. Some people stop at the tri-county metro. Others fold in the Treasure Coast and the inland ranch country. We serve the wider footprint, so this guide covers all of it.
The counties that make up South Florida
The three counties nearly everyone agrees on are Miami-Dade, Broward, and Palm Beach. Together they form the tri-county metro, home to more than six million residents and the beating heart of the region. Miami-Dade brings the big-city energy, Broward centers on Fort Lauderdale, and Palm Beach County stretches from Boca Raton north to the wealthy island of Palm Beach.
North of there sits the Treasure Coast: Martin, St. Lucie, and Indian River counties. This is a quieter, more spread-out version of coastal Florida, with towns like Stuart, Port St. Lucie, and Vero Beach. Inland, Highlands and Okeechobee counties trade the beach for lakes, ranches, and small-town living. You can browse each of these on our service area pages to see how they compare.
The three faces of the region
It helps to picture South Florida as three settings stacked side by side. First comes the coast, where barrier islands and beachfront condos command the highest prices. Next comes the suburbs, the wide band of master-planned communities and family neighborhoods a few miles inland. Last comes the country, the inland counties where land is cheap and life moves slowly.
Most buyers end up choosing among those three. A downtown Fort Lauderdale condo, a gated Boca Raton subdivision, and a five-acre parcel near Okeechobee are all South Florida, yet they feel like different worlds.
What South Florida is known for
Ask what South Florida is known for and the answers come quickly: beaches, boating, golf, and winter sunshine. The region draws snowbirds every year who trade cold northern winters for palm trees. It also draws remote workers and retirees who like that Florida charges no state income tax.
The lifestyle leans outdoor and casual. Fishing, paddleboarding, and waterfront dining fill the weekends, and the cultural scene in Miami and West Palm Beach gives the region real depth. Hurricane season runs June through November, so smart buyers factor storm-rated construction and insurance into the plan.
Cost of living across South Florida
Prices are the biggest surprise for newcomers, mostly because they vary so much. A condo steps from the sand in Palm Beach can cost several million, while a solid family home in Port St. Lucie or Sebring stays well within reach for a middle-income buyer. Property taxes and insurance also shift by county and by how close you sit to the water.
If you want the numbers, our guide to the cost of living in South Florida breaks down housing, insurance, and everyday expenses. For a tour of the towns themselves, the cities in South Florida guide walks through them county by county.
Where to buy in South Florida
The right spot depends on what you want your daily life to feel like. Beach lovers gravitate to the barrier islands and coastal condos. Families often prefer the inland suburbs, where master-planned communities offer schools, parks, and newer homes. Buyers chasing value or acreage head to the Treasure Coast and the inland counties.
Whatever your target, start by picking a county, then narrow to a few towns. From there you can compare current listings and get a feel for pricing. When you are ready, browse homes for sale across South Florida and filter by area, price, and type.
Frequently asked questions
What counties are in South Florida?
The core three are Miami-Dade, Broward, and Palm Beach. Many people also include the Treasure Coast counties of Martin, St. Lucie, and Indian River, plus the inland counties of Highlands and Okeechobee. The exact list depends on whether you define the region by geography or by metro area.
Is Orlando part of South Florida?
No. Orlando sits in Central Florida, well north of the subtropical coastal zone. South Florida generally starts around the Lake Okeechobee latitude and runs south to the tip of the peninsula.
Is South Florida a good place to live?
For many people, yes. The warm climate, coastal lifestyle, and lack of a state income tax are big draws. The trade-offs are higher home insurance, summer heat, and hurricane season, so the answer depends on your budget and priorities.
What is the difference between the tri-county area and the Treasure Coast?
The tri-county area (Miami-Dade, Broward, Palm Beach) is the dense, urban metro. The Treasure Coast (Martin, St. Lucie, Indian River) is the quieter, more spread-out coastal region just to the north, with smaller towns and lower prices.
