10 Things You Should Always Do During a Thunderstorm

Thunderstorms can turn dangerous fast. Lightning doesn’t give you a warning, and making the wrong move could put you or your family in harm’s way. These storms are unpredictable, and treating them lightly is a risk you don’t want to take.

I get it—sometimes it’s tempting to shrug it off and think, “What are the chances?” But the reality is, lightning doesn’t care about odds. A little caution goes a long way in keeping you and the people you care about safe. Here’s what you absolutely need to avoid when the sky starts to roar.

Spread Out During a Storm

Huddling together during a thunderstorm might feel comforting, but it’s actually more dangerous. Staying close increases the risk of multiple people being hurt if lightning strikes nearby. By separating from others, you reduce the chance of injuries caused by ground currents or side flashes.

It’s one of those tips that seems counterintuitive but makes a big difference. When the weather turns stormy, make sure everyone in your group knows to spread out and stay alert. And if you can, brush up on cloud patterns to recognize when a storm might be brewing—it’s always better to be ahead of the game.

Bring Your Pets Inside

Leaving your pet outside during a thunderstorm is a big no. If your dog is chained to a tree or left in a doghouse, they’re just as vulnerable to lightning as you would be in the same spot. Wooden doghouses or trees won’t protect them from the risks of a storm.

The best option? Bring them inside where it’s safe. Your furry friends are part of the family, and they rely on you to keep them out of harm’s way. A cozy spot indoors is all they need until the storm passes, and it’s peace of mind for you, too.

Wait Before Heading Back Outside

Just because the storm seems to have passed doesn’t mean it’s safe to go outside. The CDC’s “30-30” rule recommends waiting at least 30 minutes after the last clap of thunder before heading back out. Lightning can still strike even after the skies clear, so patience is key here.

It’s easy to get antsy, especially if there’s something you need to do outside. But sticking to this guideline can keep you safe. Use the time to regroup, check the weather forecast, or just enjoy a little downtime while you wait for the all-clear.

Don’t Worry About Metal Accessories

Spending time fiddling with metal items during a thunderstorm isn’t worth it. The National Weather Service says that while metal conducts electricity, it doesn’t necessarily attract lightning. Your priority should be getting to safety—not removing your watch or belt.

That said, avoid holding anything metal above shoulder level, as the CDC notes it can increase your risk of being struck. If you’re outside, skip metal fences, railings, or bleachers on your way to shelter. Focus on getting indoors quickly, where you’ll be much safer than trying to avoid every metal object along the way.

Step Back from the Windows

Windows might seem like the perfect spot to watch a storm roll through, but they’re more dangerous than you think. A lot of windows have metal parts, and if lightning strikes nearby, that metal can conduct electricity. On top of that, strong winds can send debris flying right into the glass, which could shatter and cause some serious harm.

It’s one of those things you don’t really think about until it happens. Stay safe by moving to an interior space during the storm. You can always admire the view once the skies clear, but in the moment, it’s better to be cautious.

Unplug Your Devices

Leaving your gadgets plugged in during a thunderstorm is a gamble you don’t want to take. Lightning can cause surges that fry electronics in seconds, and even the best surge protector isn’t guaranteed to save them. Unplugging your laptop, TV, and other devices takes just a minute but could save you a lot of frustration (and money).

It’s one of those “better safe than sorry” situations. Even if the storm looks like it’s staying off in the distance, it’s worth a quick check to unplug anything important.

Don’t Take Cover Under Trees

Standing under a tree during a thunderstorm might feel like the natural thing to do, especially if you’re caught in the rain. But according to John Jensenius, a lightning safety specialist with NOAA, it’s “extremely risky.” Trees are often the tallest objects around, making them a prime target for lightning strikes. The real danger? The current can jump from the tree to you, especially since the human body is a better conductor than wood.

Avoid Wide Open Spaces

Standing out in the open during a thunderstorm isn’t any safer than hiding under a tree. The CDC advises steering clear of wide, open spaces like parks, golf courses, or even your backyard. These areas leave you exposed, making you the tallest—and most vulnerable—target for a lightning strike.

Skip the Shower During a Storm

Taking a shower during a thunderstorm might seem harmless, but trust me, it’s not worth the risk. If lightning strikes nearby, the electrical current can travel through your pipes, and with water being such a good conductor, you could get seriously hurt. No one wants their shower to come with a side of danger.

As a mom, I know how tempting it is to sneak in a shower while the kids are busy—or at least not actively tearing the house apart. But during a storm, it’s just not the time. Stay dry, wait it out, and maybe use those few minutes to cuddle with the little ones or grab a snack.

Don’t Park Yourself on Concrete

Sitting on concrete during a thunderstorm? Big no-no. A lot of concrete has metal reinforcements like rebar or mesh inside, which basically makes it a lightning magnet. If the storm gets too close, you’re way better off avoiding anything that might conduct electricity.

It’s like when you’re watching your boys play outside and you sit on the patio steps for “just a minute.” Next thing you know, the storm rolls in, and you’re in the danger zone without even realizing it.
