Florida's climate varies by region, with the northern and central parts experiencing a humid subtropical climate, while South Florida enjoys a tropical climate. A distinct rainy season lasts from May through October, with afternoon thunderstorms fueled by daytime heat. These storms bring heavy but brief rainfall.
Starting in October, Florida enters its dry season, which begins early in the month in the north and later in the month in the south, lasting until late April. During this time, mid-latitude storm fronts occasionally pass through, bringing light, short-lived winter rainfall to northern and central Florida. Winters can be quite dry, and in some years, drought conditions lead to water restrictions. Although most of the state rarely sees frozen precipitation, northern Florida occasionally experiences light snow or sleet a few times per decade.
Thunderstorms
Florida experiences more thunderstorms than any other U.S. state, due to its position between two warm bodies of water—the Gulf of Mexico and the Atlantic Ocean. Sea breezes from these waters push hot air inland, where it rises and forms towering thunderclouds that generate frequent and intense thunderstorms, often with dangerous lightning.
Some areas experience more than 90 thunderstorm days per year, making Florida one of the most electrically active regions outside the tropics. The state also has the highest density of lightning strikes in the U.S., leading to several lightning-related fatalities each year. However, lightning deaths have been declining since 1992, thanks to improved safety awareness. Construction workers and outdoor laborers are at the highest risk, though a significant portion of fatalities occur indoors, particularly among people using electronic devices.
Severe thunderstorms can bring heavy rainfall, hail, strong winds, and even tornadoes. Flash flooding is also a risk, especially during intense storms. While thunderstorms are most common in summer, they can occur year-round.
Tornadoes
Florida has the highest number of tornadoes per square mile of any U.S. state, though most of these tornadoes are weaker and shorter-lived than those found in the Midwest or Deep South. Stronger tornadoes do form, typically associated with cold fronts in the winter or spring.
Tropical Cyclones and Hurricanes
Florida is no stranger to tropical cyclones, with storms affecting the state year-round, except in March. Roughly one-third of these storms occur in September, with the majority hitting between August and October, marking the peak of hurricane season. Certain areas along the coastline are the most likely to experience hurricanes, with some of the highest frequencies of intense storms in the U.S.
Hurricane season runs from June to November, with the highest activity typically in September and October.
Extreme Heat
Florida's intense heat can also pose a serious health risk, especially during the summer months. It's essential to stay hydrated, wear light-colored clothing, and seek air-conditioned shelter when possible. Prolonged exposure to extreme heat can lead to heat exhaustion, dehydration, dizziness, nausea, and in severe cases, death.
Rip Currents
Rip currents are a significant hazard in Florida, particularly along the Gulf of Mexico. These narrow, fast-moving channels of water flow away from the shore at speeds of up to eight feet per second, creating dangerous conditions for swimmers. Always exercise caution when venturing into the water.
