What Is South Florida? The Counties, Cities, and Coastal Life

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.

One name, three housing markets

The counties get listed together because they share a climate and a coastline. As places to buy property they behave differently enough that treating them as one market will cost you money.

Current figures across the eight counties we cover make the point without any interpretation needed. Miami-Dade runs about $599,000 median with roughly 21,718 active listings. Broward is around $390,000 with about 17,766. Palm Beach sits near $484,512 with roughly 12,682. Martin is about $535,000, St. Lucie about $410,000, Indian River about $399,900, Highlands about $309,000 and Okeechobee about $274,000.

That is not a gradient. Martin, a much smaller county, carries a higher median than Palm Beach. Broward, one of the largest markets in the state, sits below Palm Beach by nearly $95,000 and below St. Lucie as well. Any statement that begins "the South Florida market is" has already averaged away the thing you needed to know.

The measurement that shows what is really happening

Median price tells you what is for sale. Price per square foot tells you what it costs. The two answer different questions and the gap between them is where the useful information sits.

Broward is the clearest example. Its median of about $390,000 is well below Palm Beach's roughly $484,512, which reads as the cheaper county. Its price per square foot is about $306 against Palm Beach's $302, which is slightly higher. Broward is not cheaper. It is smaller. The lower median reflects an inventory weighted toward condominiums and attached homes rather than a lower cost of housing.

Martin runs the opposite way: a higher median than Palm Beach at about $535,000, with the lowest price per foot of the coastal group at roughly $292. That is a market where buyers are purchasing space.

So when someone tells you a county is affordable, ask which number they used. A household needing four bedrooms and a household needing two will reach opposite conclusions from the same median.

Absorption separates them further than price does

How long inventory takes to sell varies more sharply across the region than price, and it is the figure that tells a buyer or seller what their position actually is.

Palm Beach averages about 106 days and St. Lucie about 107. Broward runs about 124 and Miami-Dade about 136. Inland, Okeechobee is around 144 and Highlands about 206, roughly double the coastal pace.

Two things follow. For a seller, the same pricing mistake costs very different amounts depending on the county, since an overpriced listing in a 206-day market may sit for the better part of a year. For a buyer, a slower market is a stronger negotiating position, and the inland counties offer that alongside the lower prices rather than instead of them.

The Broward result is worth noting on its own: cheaper on the median and slower to sell than Palm Beach. That combination usually indicates a financing constraint rather than weak demand, which is exactly what an older condominium heavy inventory produces.

What the label means in practice

Where the region ends is genuinely contested, and the answer depends on who is asking.

The narrowest definition is the three southeastern counties. A wider one adds the Treasure Coast. Broadcast weather, sports coverage, state agencies and real estate boards all draw the line in slightly different places, which is why you will see the term used inconsistently and none of the uses is wrong.

The practical consequence is worth remembering when you research. A statistic labelled South Florida may or may not include the county you are buying in, and given the spread above, that inclusion or exclusion can move the number substantially. Check which counties a figure covers before you rely on it, and prefer county level data over regional data whenever you can get it.

Choosing among them

Rather than asking which county is best, work backwards from what you are actually buying with.

If the constraint is space per dollar, the inland and Treasure Coast counties give you the most of it, at the cost of distance and slower resale. If the constraint is a commute or an employment base, the coastal counties price accordingly. If the constraint is a monthly payment rather than a purchase price, insurance and association fees matter more than the price itself and vary building by building rather than county by county.

And if you are selling, the county you are in sets the pace you should expect, not the pace you read about. We can put current comparable figures against your specific address rather than the regional average.

More common questions

Which county is genuinely the least expensive?

On price per square foot, the inland counties, with Highlands around $190. On median price, Okeechobee at about $274,000. Those are different questions with different answers.

Why is Broward's median below Palm Beach's?

Inventory mix rather than cost. Broward's price per square foot is slightly higher, so buyers there are getting less space rather than a lower price for the same thing.

Does the region behave as one market?

No. Days on market alone runs from about 106 to about 206 across the counties, which is a wider spread than most regional forecasts even attempt to describe.
