Lightning Safety on the Golf Course: The NWS Rules for When to Stop Play

How we wrote this: A plain-English summary of National Weather Service guidance on lightning safety for outdoor sports, checked October 29, 2026. Always follow course and Committee instructions.
Why golfers are at risk
The NWS estimates 20 to 25 million cloud-to-ground lightning flashes a year in the U.S. About 30 people are killed each year and hundreds more injured, and about two-thirds of deaths happen during outdoor recreation. Some strikes reach well away from the storm, where people think they're safe.
When to stop
A significant lightning threat extends about 6 to 10 miles from the base of a storm. Stop play and head for shelter:
- if you see lightning;
- if you hear thunder, which usually carries about 10 miles, so the storm is in range; or
- if the sky looks threatening, because storms can develop directly overhead.
The NWS says no place outside is safe when a thunderstorm is in the area.
Where to go
- Safe: a substantial building with wiring and plumbing, such as the clubhouse. Inside, stay away from windows, doors, corded phones, plumbing and anything electrical.
- Also good: a hard-topped metal vehicle with the windows closed.
- Not safe: small shelters, such as rain shelters and sheds.
Account for the time it takes to get everyone off the course.
When to resume
Wait at least 30 minutes after the last thunder.
For clubs and event organizers
The NWS recommends a written lightning safety plan, followed without exception:
- Check the forecast before the event, and consider postponing if storms are expected.
- Name a lightning monitor: not the starter or a referee busy with other jobs, but someone empowered to stop play.
- Set out how to suspend and resume play, and where people should go.
- Plan what to do if someone is struck.
Under the Rules of Golf, players may stop play if they reasonably believe there is danger from lightning; see Rule 5.
If someone is struck
Call 911. Victims don't carry an electrical charge, so you can help right away. Give CPR or use an AED if needed. If possible, move the person somewhere safer.
