Florida lightning and thunderstorm safety
What to do at beaches, parks, outdoor events, sports, and on the water, plus Florida's lightning season and official forecast links.
Hear thunder or see lightning? Stop and get to shelter.
If you hear thunder, get into a substantial enclosed building or a hard-topped enclosed vehicle, and stay there for 30 minutes after the last thunder.
- Get out of the water and off the beach, field, court, golf course, trail, or open boat.
- Go into a substantial, fully enclosed building or a hard-topped, enclosed motor vehicle with the windows shut.
- Stay sheltered for at least 30 minutes after the last thunder. If thunder is heard again, restart the wait.
The National Weather Service says thunder means lightning is close enough to pose a danger. Do not wait for rain, a phone alert, or a lightning strike nearby. Lightning can strike beyond the area where rain is falling. If an outing is planned, identify safe shelter before starting.

What counts as safe shelter?
A hard-topped, enclosed vehicle
A hard-topped vehicle with the windows closed can provide protection. Avoid touching metal parts connected to the vehicle's exterior. A convertible, golf cart, motorcycle, bicycle, or open-sided vehicle is not equivalent shelter.
Open or small structures
Do not treat a picnic pavilion, beach shack, dugout, bus stop, carport, open garage, tent, or small shed as lightning-safe shelter. A roof alone is not enough.
Exposed places and objects
Stay away from isolated trees, hilltops, open fields, fences, poles, water, and metal objects such as golf clubs or fishing rods. Do not shelter beneath a tree.
There is no fully safe outdoor place during a thunderstorm. If caught outside with no way to reach a building or hard-topped vehicle, move away from water, isolated trees, high ground, and metal objects. Keep the group spread apart. Crouching low with as little ground contact as possible is only a last-resort harm-reduction step. It does not make being outdoors safe. Continue toward proper shelter when it is safe to move.
Lightning safety by place and activity
At a Florida beach or pool
- Leave the water immediately when thunder is heard or lightning is seen.
- Move off the beach and away from pools, docks, piers, and shoreline structures.
- Go to a substantial enclosed building or hard-topped vehicle. A lifeguard stand, open pavilion, umbrella, or beach tent is not safe shelter.
- Wait 30 minutes after the last thunder before returning to the beach or water.
Follow lifeguard instructions and posted flags. The beach warning flags guide explains the colors. Surf and rip-current risks can remain after a storm has moved away.
In a park, campground, or on a trail
- Before setting out, find the nearest substantial building and note which trailheads or areas are exposed.
- At the first thunder or lightning, leave ridges, overlooks, open areas, water, and exposed trails for a building or hard-topped vehicle.
- Do not wait under a lone tree, picnic shelter, tent, or open-sided restroom.
- Stay sheltered for 30 minutes after the last thunder. Check park alerts before resuming.
Backcountry visitors should check the forecast, carry a way to receive alerts, and choose routes with a realistic way to exit.
At an outdoor sporting event
- Coaches, officials, and organizers should designate safe buildings or vehicles before play begins.
- Stop activity and move players, staff, and spectators to shelter as soon as thunder is heard or lightning is seen.
- Do not use bleachers, dugouts, tents, or an open concession stand as shelter.
- Resume only after at least 30 minutes have passed since the last thunder, consistent with the event's safety plan.
Do not return to the field just because rain has stopped or the sky looks brighter.
At an outdoor concert, festival, or attraction
- Know where the venue's enclosed shelters are and how staff will communicate a pause or evacuation.
- When directed, or when thunder is heard, leave stages, open plazas, water attractions, and exposed queues.
- Move calmly to a substantial building or enclosed vehicle. Avoid crowding under a tent or pavilion.
- Wait for the organizer's all-clear after the required 30-minute thunder-free period.
Check the organizer's weather policy before buying a ticket or traveling.
On a boat, dock, kayak, or paddleboard
- Check the marine forecast and radar before leaving shore. Postpone if thunderstorms are expected.
- Head for safe harbor early when storms are forecast nearby. Do not wait until lightning is overhead to begin a long crossing.
- Get off the water and into a substantial building or hard-topped vehicle as soon as it is safe to reach one.
- A small open boat offers little protection. If caught out, follow the vessel's safety plan and official Coast Guard and NWS guidance. In a boat with an enclosed cabin, stay inside and avoid metal and electrical equipment.
Thunderstorms can also bring sudden wind shifts, rough seas, waterspouts, heavy rain, and poor visibility. Florida boat and personal watercraft rules are in the boating and Jet Ski guide.
While driving in a thunderstorm
- Reduce speed, increase following distance, and turn on headlights when visibility is reduced.
- Never drive through standing or moving floodwater. Turn around and find another route.
- If visibility becomes unsafe, pull completely off the travel lane to a safe place if possible. Do not stop under a tree or beside a downed power line.
- Follow road-closure signs and official directions. Check Florida 511 for traffic incidents and closures.
Heavy rain can hide flooded pavement and debris. Do not use a phone while driving.
Florida lightning season: when storms are most common
Florida has thunderstorms in more than one season, but the greatest everyday lightning concern for many outdoor plans comes with the warm, humid months. As the sun heats the land, Atlantic and Gulf sea breezes can move inland and collide, helping storms form, often during the afternoon and evening in the peninsula.
National Weather Service climate information for east-central Florida describes a typical wet-season onset in late May, frequent summer showers and lightning, and a drier pattern in the cooler months. NWS Melbourne's published lightning climatology shows activity increasing in May, being especially active in June through August, and usually dropping in November and December. That lightning map is based on 1986-1995 observations, so treat it as historical seasonality. It is not a current-year forecast or an exact ranking for every county.
| Period | Typical planning pattern | What to do |
|---|---|---|
| January-April | Lightning is generally less frequent than in the summer wet season, but fronts can still bring thunderstorms, especially in North Florida and the Panhandle. | Check the local forecast before outdoor events, beach days, and boating. A lower seasonal risk does not make a storm safe. |
| May | Storm and lightning activity typically increases as heat, humidity, and sea-breeze storms build. | Begin checking the afternoon forecast and radar before parks, sports, and beach plans. |
| June-August | Frequent warm-season thunderstorms and lightning are common in many parts of Florida. Storms often develop in the afternoon or evening, but timing varies by location and day. | Plan outdoor activities earlier when possible. Identify shelter before arrival, and be ready to stop early. |
| September-October | Warm-season storms can continue. Tropical systems, fronts, and changing wind patterns can alter local storm timing. | Check forecasts, marine conditions, watches, warnings, and venue updates. Do not assume the end of summer means lightning is over. |
| November-December | Lightning activity generally decreases, though passing fronts and isolated storms still occur. | Keep the same thunder rule: seek shelter immediately and wait 30 minutes after the last thunder. |
This is a historical pattern, not a forecast. Florida is large. The Panhandle, North Florida, Central Florida, South Florida, the Atlantic coast, Gulf coast, and Keys can have different storm timing on the same day. Use the forecast for the exact location and marine zone.
Official forecasts, alerts, and marine conditions
Use more than one way to receive weather information, especially on a beach, trail, boat, or large outdoor venue. A lightning-specific warning may not be issued for every storm. If you hear thunder, act immediately even if the phone has no alert.

If someone is struck by lightning
Call 911. It is safe to touch the person and begin first aid. A lightning-strike victim does not carry an electrical charge. Do not delay help out of fear of being shocked.
- Make sure it is safe to reach the person. Move them only if they remain in immediate danger and it is safe to do so.
- Call 911 and follow the dispatcher's instructions.
- If the person is not breathing normally or has no pulse, begin CPR if trained or if the dispatcher is giving the steps. Use an AED as soon as one is available.
- Check for other injuries and continue care until emergency responders arrive.
Lightning injuries can be serious even when burns are not obvious. Get professional medical help.

Lightning safety myths that can get people hurt
- "It is not raining here." Lightning can strike outside the rain area. Thunder means seek shelter.
- "The storm moved past us." Wait 30 minutes after the last thunder before returning outside.
- "A pavilion or tent will keep us safe." Open structures do not provide the protection of a substantial enclosed building or hard-topped vehicle.
- "We can finish this point, hole, set, or song." Stop when thunder is heard or lightning is seen. Do not wait for a convenient break.
- "A phone warning will always arrive first." Alerts can be delayed, unavailable, or missed. Follow the thunder rule whether or not an alert appears.
- "The person who was struck is electrically charged." They are safe to touch. Call 911 and provide first aid.
Florida lightning questions
How far away can lightning strike?
Lightning can strike several miles from the thunderstorm and beyond the area where rain is falling. If you can hear thunder, the National Weather Service says you are close enough to be at risk; go to safe shelter.
How long should I wait after thunder before going outside?
Wait at least 30 minutes after the last thunder. If you hear thunder again, restart the 30-minute count.
Is a beach pavilion or picnic shelter safe during lightning?
No. Open pavilions, picnic shelters, beach shelters, dugouts, tents, and carports are not a substitute for a substantial enclosed building or hard-topped enclosed vehicle.
Can I touch someone who has been struck by lightning?
Yes. A lightning-strike victim does not carry an electrical charge. Call 911 immediately and provide first aid if it is safe to reach them.
What months have the most lightning in Florida?
Florida lightning activity generally increases in late spring and is highest during the summer wet season. NWS Melbourne's historical lightning climatology shows especially active conditions in June, July, and August. The pattern varies by region and year; use the current local forecast.
Is there a lightning warning for every thunderstorm?
No alert should be treated as a prerequisite for taking shelter. Forecasts and thunderstorm alerts are useful, but thunder itself is the cue to get indoors or into a hard-topped enclosed vehicle.
What should boaters do if a storm approaches?
Check marine forecasts before departure and head to safe harbor early when storms are forecast nearby. If caught out, follow your vessel's emergency plan and current NWS and Coast Guard guidance. A small open boat offers little protection from lightning.
