As march weather in florida keys takes center stage, it’s worth noting that the unique geography of the Florida Keys plays a significant role in shaping the region’s climate. The Gulf Stream, a warm ocean current, significantly affects the temperature and humidity of the area.
The Florida Keys’ climate is distinct from the rest of South Florida, making it a popular destination for those seeking a subtropical experience. The Keys’ microclimate is influenced by their unique geography, with the waters of the Gulf Stream keeping temperatures mild throughout the year.
The Florida Keys’ Unique Microclimate Influences March Weather Patterns: March Weather In Florida Keys

The Florida Keys’ unique geography and proximity to the Gulf Stream create a distinct microclimate that shapes the region’s weather patterns during the month of March. Located at the tip of the Florida peninsula, the Florida Keys face the Atlantic Ocean to the east and the Gulf of Mexico to the west, resulting in a subtropical climate with mild winters and warm summers.
The Unique Geography of the Florida Keys
The Florida Keys are a 120-mile-long chain of islands that stretch from the southern coast of Florida to Cuba. The Keys are a low-lying archipelago, with an average elevation of less than 10 feet above sea level. The islands are composed of a combination of coral, limestone, and sand, which have been eroded over time by the ocean’s currents and waves. This unique geography plays a significant role in shaping the region’s climate, as the islands provide a barrier against the cold winter air from the north and the warm ocean currents from the south.
The Role of the Gulf Stream in Shaping the Temperature and Humidity of the Area
The Gulf Stream, a warm ocean current that originates in the Gulf of Mexico and flows northward along the eastern coast of the United States, has a significant impact on the climate of the Florida Keys. The Gulf Stream brings warmth and moisture to the region, resulting in mild winters and warm summers. The warm waters of the Gulf Stream also keep the temperature of the air above it warm, which in turn keeps the temperature of the region relatively stable throughout the year.
Comparing March Weather in the Florida Keys to the Rest of South Florida
March weather in the Florida Keys is generally warmer and drier than in the rest of South Florida. The average high temperature in March is around 75°F (24°C) in the Florida Keys, compared to around 72°F (22°C) in Miami and 70°F (21°C) in Fort Lauderdale. The relative humidity is also lower in the Florida Keys, averaging around 60% in March compared to around 70% in Miami and 80% in Fort Lauderdale. Additionally, the Florida Keys receive significantly less rainfall in March, with an average of around 2 inches (5 cm) of precipitation compared to around 3-4 inches (7.6-10.2 cm) in the rest of South Florida.
The Florida Keys’ unique microclimate is a result of the combination of its geography and the influence of the Gulf Stream.
