Weather Florida Keys February is a unique phenomenon where warm waters of the Gulf Stream converge with cold fronts from the North, creating a distinct weather pattern. The Florida Keys, located at the southern tip of Florida, experience a subtropical climate influenced by both Atlantic and Gulf of Mexico ocean currents.
February is a transitional month in the Florida Keys as it marks the end of the dry season and the beginning of the wet season. This convergence of warm and cold air masses brings about fluctuations in temperature, precipitation, and humidity.
The Florida Keys’ Weather Patterns in February
The Florida Keys’ subtropical climate makes February a unique month for weather patterns. As the cold winter months approach in the North, the Florida Keys experience a distinct weather phenomenon due to the interaction of warm and cold air masses.
During February, the Florida Keys are influenced by the warm waters of the Gulf Stream, which maintains a relatively high temperature throughout the month. The average high temperature in Key West, the southernmost point in the continental United States, is around 75°F (24°C), while the average low temperature is around 63°F (17°C).
The Role of the Gulf Stream
The Gulf Stream is a warm ocean current that originates in the Gulf of Mexico and flows northward along the eastern coast of the United States, including the Florida Keys. In February, the Gulf Stream plays a significant role in shaping the Florida Keys’ weather patterns by warming the air above the waters. This warm air then interacts with the cold fronts from the North, creating a distinct weather phenomenon.
- The Gulf Stream’s warm waters warm the air above the surface, increasing the temperature by 5-10°F (3-6°C) in some areas.
- As the warm air rises, it creates a region of low pressure near the surface, drawing in cooler air from the North.
- The interaction between the warm and cold air masses creates a unique weather phenomenon, characterized by rapid temperature fluctuations and frequent changes in weather conditions.

This rapid temperature change creates a unique weather phenomenon, characterized by rapid changes in weather conditions, including rain showers, thunderstorms, and periods of clear skies.
- The average high temperature in Key West, Florida, is around 75°F (24°C) on February 1st, but drops to around 65°F (18°C) by February 15th.
- The average low temperature in Key West, Florida, is around 63°F (17°C) on February 1st, but drops to around 53°F (12°C) by February 15th.
- The relative humidity in Key West, Florida, decreases from an average of 74% on February 1st to 63% by February 15th, reflecting the decrease in temperature and the increase in atmospheric pressure.
Extreme Weather Events in the Florida Keys

The Florida Keys are a subtropical region, prone to various extreme weather events, including tropical storms and hurricanes, that can have devastating impacts on the local population and economy. Among these, rare but intense storms are particularly destructive, causing widespread damage and loss of life.
Rare but Potentially Devastating Storms
February is not the typical season for hurricanes in the Florida Keys; however, the region can experience intense winter storms, especially those influenced by cold fronts and low-pressure systems that bring heavy rain and high winds. Some notable examples of rare but intense storms that have affected the Florida Keys in February include:
The Great Miami Hurricane of 1926
On September 18, 1926, the Florida Keys were devastated by the Great Miami Hurricane, which made landfall in southern Florida on September 18, 1926. Although it occurred in September, it is included in this section and has affected Florida Keys in a different way – by a massive hurricane surge, especially in the southern keys and Miami. This storm caused catastrophic damage to the Florida Keys, particularly in Key West, wiping out much of the city, including buildings, infrastructure, and homes. The storm surge was particularly destructive, inundating the Keys and causing widespread flooding.
The Okeechobee Hurricane of 1928
On September 17, 1928, the Okeechobee Hurricane made landfall in eastern Florida, affecting the Florida Keys through a secondary effect known as storm surge – a phenomenon that brings water from ocean to a landlocked region, causing widespread flooding and destruction in inland regions. Although it occurred in September, the storm affected Florida Keys by a massive flooding and water overflow from Lake Okeechobee.
The Labor Day Hurricane of 1935
On September 2, 1935, the Labor Day Hurricane, one of the most intense hurricanes in U.S. history, struck the Florida Keys, particularly the Lower Keys. The storm made landfall with winds of 185 mph, causing catastrophic damage to the Keys, particularly in the cities of Islamorada and Tavernier. The hurricane’s storm surge caused widespread flooding, destroying homes, infrastructure, and businesses.
The Great Florida Keys Flood of 1948
On October 26-31, 1948, an intense low-pressure system brought heavy rain to the Florida Keys, causing widespread flooding and damage to homes and infrastructure. The storm was not a hurricane but a low-pressure system, which brought significant amounts of rain to the area.
The Great Halloween Storm of 1991
On October 31, 1991, a strong cold front brought a significant storm to the Florida Keys, with sustained winds of up to 60 mph and heavy rain. The storm caused widespread flooding and damage to homes, infrastructure, and businesses.
Potential Consequences of Rare But Intense Storms
The potential consequences of rare but intense storms in the Florida Keys are significant, including:
– Widespread damage to homes, infrastructure, and businesses
– Loss of life and property
– Disruption of transportation and communication networks
– Damage to local agriculture and fisheries
– Long-term economic impacts on the local economy
These events highlight the importance of preparedness and resilience in the face of extreme weather events in the Florida Keys.
Impact of Weather Patterns on Tourist Season in the Florida Keys: Weather Florida Keys February
