Here’s a quick answer: Florida’s climate is considered humid subtropical rather than tropical due to its temperate winters and seasonal rainfall patterns.
In this article, we’ll take an in-depth look at Florida’s climate characteristics and temperature and precipitation patterns throughout the year. We’ll examine how Florida compares to true tropical climates and explain the important differences that make most of the state subtropical instead. Whether you’re visiting Florida or have lived there for years, understanding these climate classifications helps explain Florida’s unique weather and seasons.
Defining Tropical vs. Subtropical Climates
When it comes to Florida’s climate, it is important to understand the distinction between tropical and subtopical climates. While both are characterized by warm temperatures and high humidity, there are some nuances that set them apart.
Temperature
One of the key factors in distinguishing between tropical and subtopical climates is temperature. Tropical climates are typically characterized by consistently high temperatures throughout the year, with little variation between seasons.
In contrast, subtopical climates have more distinct seasons, with cooler temperatures during the winter months.
For example, Miami, located in the southern part of Florida, experiences average high temperatures of around 90°F (32°C) in the summer and 75°F (24°C) in the winter. This is an example of a subtopical climate with its mild winters.
On the other hand, Key West, also in southern Florida, has average high temperatures of around 87°F (31°C) in the summer and 75°F (24°C) in the winter, showcasing a tropical climate with its consistently high temperatures throughout the year.
Rainfall Patterns
Another significant factor in differentiating between tropical and subtopical climates is rainfall patterns. Tropical climates are characterized by high levels of rainfall throughout the year, with no distinct dry season. In contrast, subtopical climates have more distinct wet and dry seasons.
For instance, Miami receives an average of 62 inches (157 cm) of rainfall annually, with the wettest months being June through September. This is indicative of a subtopical climate with its distinct wet and dry seasons.
On the other hand, Key West receives an average of 39 inches (99 cm) of rainfall annually, with precipitation more evenly distributed throughout the year. This is an example of a tropical climate with its consistent rainfall patterns.
Climate Zones
Florida can be divided into different climate zones based on its tropical and subtopical characteristics. The southern part of the state, including cities like Miami and Key West, falls under the tropical climate zone.
This region experiences consistently high temperatures and abundant rainfall throughout the year.
The central and northern parts of Florida fall under the subtopical climate zone. These areas experience more distinct seasons, with cooler temperatures during the winter and a more pronounced wet and dry season.
It is important to note that while Florida as a whole is considered to have a tropical or subtopical climate, there can be variations within different regions of the state. Factors such as proximity to the coast, elevation, and proximity to other geographical features can influence local climate patterns.

South Florida’s Tropical Influences
Proximity to the Tropics
One of the main reasons why South Florida is known for its tropical influences is its proximity to the Tropics. Located between the 25th and 31st parallel, this region falls within the subtropical climate zone.
However, being closer to the Tropics than any other part of the United States, South Florida experiences many characteristics typically associated with a tropical climate.
The warm waters of the Gulf Stream, which flows just off the coast of South Florida, contribute to the region’s tropical feel. This current brings with it warm, moist air from the Caribbean, resulting in balmy temperatures and high humidity levels.
These conditions are perfect for the growth of lush vegetation, including palm trees and tropical flowers, giving the area its distinct tropical vibe.
Occasional Frost
While South Florida is predominantly influenced by tropical weather patterns, it is important to note that occasional frost can occur in this region. During the winter months, cold fronts from the north can push into Florida, bringing cooler temperatures.
Although these cold snaps are usually short-lived, they can result in frost forming on plants and even light freezes in some areas.
Despite these occasional dips in temperature, South Florida’s overall climate remains warm and tropical throughout the year. The mild winters are one of the reasons why this region is a popular destination for snowbirds seeking respite from colder climates.
Year-Round Rainfall
Another characteristic of South Florida’s tropical influences is its year-round rainfall. The region experiences a pronounced wet season, typically occurring from May through October, which is influenced by the Caribbean climate.
During this time, daily afternoon showers and thunderstorms are common, providing much-needed relief from the heat and humidity.
South Florida also benefits from a more subtle dry season, which typically occurs from November through April. Although rainfall is generally less frequent during this period, it still receives enough precipitation to support its lush vegetation and maintain its tropical ecosystem.
North and Central Florida’s Subtropical Nature
When it comes to the climate in North and Central Florida, the region can be described as having a subtopical nature. While it does have some characteristics of a tropical climate, there are also distinct differences that set it apart.
Cooler Winters
One of the key factors that differentiate North and Central Florida’s climate from a purely tropical climate is the presence of cooler winters. While the summers in this region can be hot and humid, the winter months bring cooler temperatures, especially in the northern parts of the state.
This is due to the influence of cold fronts that move down from the north, bringing cooler air and occasionally even frost and freezes.
Distinct Wet and Dry Seasons
Another characteristic of the subtopical climate in North and Central Florida is the presence of distinct wet and dry seasons. The region experiences a wet season during the summer months, typically from June to September, when frequent thunderstorms and heavy rainfall are common.
This is followed by a drier season during the winter months, when rainfall is less frequent and the air is generally drier. This seasonal variation in precipitation is a key characteristic of a subtopical climate.
Freezes and Frost
While North and Central Florida may not experience freezes and frost as frequently as more northern regions, they do occur from time to time, especially during the winter months. These cold snaps can have a significant impact on agriculture and vegetation in the area.
Farmers and gardeners in the region must take precautions to protect their crops and plants during these colder periods.
Temperature Patterns Across Florida
Florida’s climate is often associated with warm and sunny weather, but the state’s temperature patterns exhibit some interesting nuances. The combination of its location and geographical features contribute to a unique climate that can be classified as both tropical and sub-tropical.
North-South Gradient
One of the key factors influencing temperature patterns in Florida is its north-south gradient. As you travel from north to south, you will notice a gradual increase in average temperatures. The northern parts of the state experience a more sub-tropical climate, characterized by mild winters and warm summers.

Comparing Florida to True Tropical Climates
More Temperature Variation
While Florida is often associated with warm and sunny weather, it is important to note that its climate differs from true tropical climates in several ways. One of the noticeable differences is the amount of temperature variation experienced in Florida.
In true tropical climates, such as those found in countries like Thailand or Brazil, temperatures tend to remain relatively stable throughout the year. However, in Florida, temperatures can fluctuate significantly, especially during the winter months.
It is not uncommon to experience cooler temperatures in the northern parts of the state, while the southern regions maintain a more tropical feel.
Pronounced Dry Season
Another distinction between Florida’s climate and true tropical climates is the presence of a pronounced dry season. In many tropical regions, rainfall is abundant throughout the year, creating lush rainforests and tropical vegetation.
In contrast, Florida experiences a distinct dry season, typically occurring during the winter months. This dry season can result in drier landscapes and a decrease in overall precipitation. However, it is important to note that Florida’s rainy season, which spans from May to October, is still characterized by frequent and heavy rain showers.
Fewer Tropical Rainforests
While Florida boasts a diverse range of ecosystems, including wetlands, marshes, and coastal areas, it is not known for its extensive tropical rainforests. True tropical climates are often home to lush rainforests teeming with unique flora and fauna.
In Florida, however, the landscape is primarily dominated by subtropical vegetation, such as pine forests and palm trees. The absence of extensive tropical rainforests in Florida is primarily due to its climate, which falls within the subtropical category rather than the tropical category.
So, while Florida may have some similarities to true tropical climates, such as warm temperatures and a lush environment, it also has distinct differences. The temperature variations, presence of a pronounced dry season, and absence of extensive tropical rainforests are all factors that set Florida apart from true tropical climates.
Conclusion
While often perceived as a tropical paradise, the majority of Florida experiences a humid subtropical climate with distinct seasons. Only far south Florida exhibits truly tropical characteristics like rare winter frosts and year-round rainfall. For most of the state, seasonal temperature swings and precipitation patterns align more closely with subtropical classification. Nonetheless, Florida’s abundance of sun, heat and lush vegetation give it a tropical personality all its own.
