The Atlantic hurricane season runs from June 1 to November 30, and South Florida's rainy season covers much of the same stretch, so a rental car here can meet a violent afternoon downpour, a flooded street on a clear day or, less often, a named storm. A low sports car and an open-top convertible are the most exposed. Know what your rental agreement says about water damage, avoid standing water, and have a plan if a storm is forecast during your trip.
The seasons in plain terms
| Period | What to expect | Rental-car implications |
|---|---|---|
| December to April | Drier, milder, the peak tourism months | Best driving weather, highest demand |
| May to August | Hot and humid; the rainy season sets in, with frequent afternoon thunderstorms | Afternoon downpours, flash flooding, lightning, heat |
| September to November | The busiest weeks of the hurricane season, then fall king tides | Sunny-day flooding of low streets in some areas; monitor forecasts and check cancellation terms |
The official Atlantic hurricane season runs from June 1 to November 30, so it covers most of the last two periods. The National Hurricane Center posts forecasts and advisories at nhc.noaa.gov. The local National Weather Service office issues the flash-flood and thunderstorm warnings that matter day to day.
Daily downpours
In the wet season, storms often build in the afternoon, drop heavy rain for 20 to 60 minutes and clear. Visibility can fall quickly, and roads that drain slowly may pond at underpasses and intersections. Turn on your headlights, which Florida law requires during any rain, slow down and leave extra distance. In an open-top car, close the roof before the clouds arrive; a soaked interior can mean a cleaning charge, and many convertible roofs take several seconds to close and only operate at low speeds, so you cannot leave it to the last moment.
Lightning is a real hazard. A hard-top is much safer than a convertible, but neither is a shelter if you are standing beside it. Pull over somewhere safe if you cannot see.
Sunny-day flooding and king tides
Parts of South Florida can flood without a cloud in the sky. During the highest tides of the year, usually in the fall, seawater can back up through storm drains and spill onto low streets, particularly on the bay side of Miami Beach and in some low waterfront neighborhoods on the mainland. Salt water is hard on a car's underside and brakes, and rain on top of a king tide makes the flooding worse. If your plans include low-lying streets or older garages near the water, check the day's tide times and forecast; local news and city alerts usually flag king tide dates in advance.
Standing water and low cars
The National Weather Service slogan is "Turn Around, Don't Drown," and the advice is the same for a rental: do not drive through water that you cannot see the bottom of. The depth is hard to judge, the pavement may be missing, and water can disable a car or enter the engine intake. A low supercar is particularly vulnerable, as are cars with air intakes or electrical components near the ground. Flood damage is expensive and can lead to a total loss.
Check your agreement for the exact wording on water damage. Flood or water damage is a common exclusion from rental waivers, and you may be liable for the car's full value if you drive into water. Our insurance guide explains how to read these clauses and what to ask the company in advance.
If a hurricane or tropical storm is forecast
- Call the rental company early. Ask about changing or cancelling dates, the refund policy and whether it will allow you to return the car early.
- Check your accommodation and your evacuation zone. Miami-Dade County publishes evacuation zone information. If an evacuation order covers your hotel, you may have to leave quickly.
- Do not park in a flood-prone spot. A covered upper level (not the open roof deck) of a solid parking garage is better than an open lot near the water, and low garage basements should be avoided.
- Fill the tank. Long queues at gas stations and local shortages are common before a storm, and premium fuel for a supercar may be the first to run out.
- Document the car. Take photographs before and after storm exposure, as in the pickup and return checklist.
- Do not drive during dangerous conditions. Sheltering in place is almost always safer than driving through a tropical storm.
Heat and sun
South Florida summers are hot and humid, and the interior of a car left in the sun gets hotter than the air. A dark-leather supercar can be uncomfortable to enter, and a closed car heats fast. Use a sunshade when you can, park in shade or in a garage, and bring water. Check the air conditioning before you accept the car, and ask the company what to do if a warning light comes on in the heat.
Planning your trip around the weather
If you are flexible, schedule scenic drives in the morning and keep afternoons for indoor activities. Some of the loops in our scenic drives guide are best done early for this reason. The seasons and events guide compares the busy winter market with the quieter, rainier months.
Frequently Asked Questions
When is hurricane season in Florida?
The Atlantic hurricane season runs from June 1 to November 30, according to the National Hurricane Center. Most storm impacts in Florida occur in the late summer and early fall.
Can a car rental be cancelled because of a hurricane?
Policies vary by company. Ask about weather-related changes and refunds when you book, and get the answer in writing.
Where should I park a rental if a storm is coming?
On a covered upper level (not the open roof deck) of a solid parking garage away from the water, rather than on the street, in an open lot or in a basement. Tell the rental company where the car is.
What are king tides?
They are the highest tides of the year, usually in the fall, and they can flood low streets in parts of South Florida even without rain.
Is it safe to drive a convertible in summer rain?
Short tropical showers are manageable if you close the roof in time, but lightning and flooded streets are real risks. Pull over and wait out heavy storms.
