What to Do During a Thunderstorm? Safe Behavior in the City, Mountains, and Near Water

Thunderstorm in the City

During a thunderstorm in the city, the most important thing is to quickly find safe shelter—preferably inside a solid building. It's best to avoid staying on the top floors, as lightning tends to strike the highest points of a structure. Instead, seek refuge on lower floors, away from windows.

Avoid standing under trees, streetlights, or power poles, as these can easily become targets for lightning strikes. If you are outdoors and hear thunder or see lightning, do not stay out on the streets—find a safe place to wait out the storm as quickly as possible.

At home, during a thunderstorm, remember to turn off electrical devices and unplug them from the power outlets, as a sudden lightning strike can cause power surges and damage your equipment. Also, avoid contact with water—do not use taps, wash dishes, or take a shower, as pipes can conduct electricity.

Thunderstorm in the Mountains

A thunderstorm in the mountains can be especially dangerous due to open spaces and exposed trails. The most important rule is to quickly descend to a lower, safer place. Climbing to peaks or staying on ridgelines during a storm is extremely risky because the highest points are the most vulnerable to lightning strikes.

During a thunderstorm, avoid standing near solitary trees, rocks, or other tall objects that can act as conductors for lightning. Instead, look for a depression in the terrain, such as a small ditch or hollow, where you can take cover.

In such situations, the best position is to crouch down with your feet together, wrapping your arms around your knees, trying to keep as little of your body in contact with the ground as possible. It’s important not to lie flat or stretch out on the ground.

When in the mountains during a storm, avoid camping in open areas. If the weather forecast predicts thunderstorms, it’s better to pitch your tent in a more sheltered location or temporarily move your campsite to a safer shelter during the bad weather.

Thunderstorm Near Water (Lake, River, Sea)

During a thunderstorm near water, the most important thing is to get out of the water immediately. Whether you’re kayaking, boating, or simply swimming in a lake or river, leave the water as quickly as possible. Water and metal parts of boats are very dangerous during a storm as they conduct electricity.

Once out of the water, find shelter on land as soon as possible—ideally in a solid building or a car. These are places that offer protection from lightning strikes.

Avoid standing on the beach, under trees, or near metal structures like masts or fences. These spots are particularly dangerous as lightning easily strikes tall, exposed objects.

If you can't find safe shelter, crouch down as low as possible with your feet together, minimizing your contact with the ground. Remember to avoid touching water and metal objects, as they increase the risk of electrocution.

What You Should Absolutely Not Do During a Thunderstorm

There are many behaviors during a thunderstorm that significantly increase the risk of being struck by lightning. First and foremost, never take shelter under a solitary tree—such places act like natural lightning rods and are among the most dangerous during electrical storms.

Also, avoid staying in open spaces without any cover. Lack of protection exposes you to direct lightning strikes or injuries from strong winds and hail.

Never hold metal objects such as bicycles, trekking poles, tools, or railings—metal is an excellent conductor of electricity and increases the risk of being struck.

At home, do not use electrical appliances plugged into the grid—a lightning strike can cause severe power surges that may damage your equipment and pose a danger to your health.

Lastly, never swim or stay in the water during a thunderstorm. Water conducts electricity very well, and being in it during lightning activity is one of the most dangerous things you can do.

Preparing for a Thunderstorm – What’s Good to Have on Hand

Good preparation for a thunderstorm means gathering essential items that may come in handy in an emergency. First and foremost, it's a good idea to have a flashlight and a power bank to ensure light and the ability to charge your phone even during power outages. Don’t forget to have a supply of water and food, especially if the storm lasts longer or causes transportation difficulties.

Your phone should be fully charged before the storm, but it’s best to avoid using it outdoors during lightning to reduce the risk of electric shock.

It’s also wise to have a first aid kit nearby—in case of minor injuries that might occur during the storm or evacuation.

Don’t forget to regularly check the weather forecast using a smartphone app or a radio. This way, you’ll stay updated on incoming storms and can prepare in advance.
