Ever found yourself on a perfect summer day lounging by the pool or at the beach, when suddenly the sky darkens, and the unmistakable rumble of thunder shatters the tranquility? It’s a common scenario that leaves many of us in a conundrum: Should we brave the ominous clouds and stay in the water, or should we pack up our things and seek shelter? After all, what are the odds that we would be in any real danger?
Swimming during a thunderstorm is highly dangerous and should be avoided. The risks are numerous and serious. From the potential of getting struck by lightning, to the ripple effect of storm-induced water hazards, the dangers are both immediate and far-reaching. No leisurely swim is worth risking your safety and potentially your life.
In this article, we will take a deep dive into the reasons why swimming during a thunderstorm is a bad idea.
Why It’s Not Safe to Swim During a Thunderstorm
Risk of Being Struck by Lightning
The most significant and immediate danger of swimming during a thunderstorm is the potential to be struck by lightning. This is because water is a fantastic conductor of electricity. When a lightning bolt strikes the surface of a body of water, the electrical current disperses in all directions, potentially covering large areas.
If you happen to be swimming during this time, you could be electrocuted, even if the lightning bolt hits the water quite far from where you are. The human body is mostly made of water, which means we, too, conduct electricity rather well, making us prime targets for a dispersed electrical charge.
The severity of injuries can range from burns and cardiac arrest to severe neurological damage, and unfortunately, it can also result in instant death.
Shockwave Injuries
Lightning strikes are powerful events. When they hit water, they cause an immediate and dramatic increase in temperature, leading to a rapid expansion and contraction of the water – a phenomenon known as a shockwave.
This shockwave moves through the water at an extremely high speed and can cause a variety of physical injuries to anyone swimming in its path. The force of the shockwave can rupture eardrums, which not only is painful and disorientating but can also compromise your balance.
It can also cause blunt force trauma injuries similar to what you might experience in an explosion, including potential internal injuries. Imagine being punched from every direction at once, and you’ll have an idea of what a shockwave might feel like.
Drowning Due to Panic or Disorientation
A thunderstorm is a chaotic event – loud claps of thunder, blinding flashes of lightning, rapid changes in weather conditions. For a swimmer, this chaos can be not only unsettling but also disorienting.
A sudden, loud clap of thunder can trigger a fight-or-flight response. In water, this can lead to panicked, uncontrolled movements, which increase the risk of inhaling water and drowning.
Additionally, the sudden brightness from a lightning flash can temporarily impair vision, making it difficult to navigate in the water, increasing the risk of accidents and making it harder to reach safety.
Decreased Visibility
During a thunderstorm, heavy rain can significantly reduce visibility both in and around the water. This reduced visibility can be hazardous for several reasons.
Firstly, it makes it more difficult for you to spot hazards in the water, such as floating debris, rocks, or other swimmers. Colliding with such hazards can lead to injuries.
Secondly, it can make it harder for you to navigate your way back to shore or spot safety equipment or exits from the water.
Lastly, if you’re in trouble, decreased visibility makes it harder for others to see you and provide assistance, increasing the risk of a bad situation becoming worse.
Dangerous Sea or Lake Conditions
Thunderstorms often bring with them strong winds and heavy rain, causing water conditions to deteriorate rapidly. Seas, lakes, and even rivers can become choppy, with larger than usual waves making it difficult to swim or float. These conditions can rapidly exhaust even experienced swimmers.
Additionally, in coastal waters, thunderstorms can cause rip currents – powerful, narrow channels of fast-moving water. These currents can pull swimmers away from the shore quickly and without warning. Fighting against a rip current is near impossible and can lead to exhaustion and drowning.
Inaccessibility of Help
During a thunderstorm, the availability of help in case of an emergency might be significantly reduced. Lifeguards, if present, may have taken shelter from the storm, and other potential rescuers might be fewer in number as people generally avoid water during such weather.
The reduced visibility and hazardous conditions also make it difficult for any rescuer to reach someone in trouble in the water quickly. Plus, thunderstorms can disrupt communication systems, making it harder to call for help or for emergency services to coordinate a rescue operation. This lack of available help increases the risk of a minor problem escalating into a serious one.
Frequently Asked Questions
Can lightning strike me if I’m swimming in a pool during a thunderstorm?
Yes, it can. If lightning strikes the water in a swimming pool, the electrical charge can disperse across the water and potentially electrocute anyone swimming in it. Pools, especially those made of concrete or metal, can also conduct the electricity from a nearby lightning strike, posing a risk to swimmers.
Moreover, if you’re swimming, your head might be the highest point in an otherwise flat area, making you a possible target for a direct strike. Therefore, it’s crucial to exit the water at the first sign of a thunderstorm, even if it seems distant.
What should I do if I’m caught swimming during a thunderstorm?
If you’re swimming and a thunderstorm approaches, the safest action is to get out of the water as soon as possible. Once you’re out of the water, seek shelter immediately. Avoid standing under tall, isolated objects like trees or poles, as they can attract lightning.
If you’re at the beach, head to your vehicle if it’s safe to do so, or find a substantial building to take shelter in. Remember to stay away from windows, electrical equipment, and plumbing, as these can also conduct electricity if lightning strikes the building.
How far away does a thunderstorm have to be to make swimming unsafe?
The “30/30 Rule” is a helpful guideline for this situation. If the time between a flash of lightning and the sound of thunder is 30 seconds or less, the thunderstorm is close enough to pose a threat, and you should seek shelter. This typically corresponds to a distance of about six miles. However, lightning can strike from further away, so if you hear thunder at all, it’s safer to stay out of the water.
Can I swim indoors during a thunderstorm?
While an indoor pool is safer than an outdoor one during a thunderstorm, it’s not entirely risk-free. Lightning can travel through plumbing and electrical systems, so if a building gets struck by lightning, it can potentially electrify the water in an indoor pool. It’s best to avoid swimming during a thunderstorm, regardless of whether the pool is indoors or outdoors.
Are certain types of bodies of water more dangerous than others during a thunderstorm?
In terms of lightning strikes, all bodies of water pose a risk as they all conduct electricity. However, larger bodies of water like oceans and lakes might be more dangerous due to the additional hazards they present during a thunderstorm. These include larger waves, strong winds, and rapid currents, all of which can make swimming more difficult and increase the risk of drowning.
Additionally, it’s often more difficult to quickly get out of a large body of water and find shelter than it is with smaller bodies of water, like swimming pools.
What are the risks of swimming soon after a thunderstorm?
While the risk of lightning strikes decreases once a thunderstorm has passed, other hazards may remain. The water could be churned up, making it more difficult to swim. Debris washed into the water during the storm could pose a risk of injury.
In coastal areas, rip currents caused by the storm could remain a threat. Also, heavy rain can wash contaminants and pathogens into bodies of water, increasing the risk of waterborne diseases.
How long should I wait after a thunderstorm before it’s safe to swim again?
As a continuation of the “30/30 Rule”, you should wait at least 30 minutes after the last sound of thunder before going back into the water. This gives enough time for the thunderstorm to move away and reduces the risk of a lightning strike.
Remember the 30/30 “rule” is just a rule of thumb. The danger is not necessarily gone the second 30 minutes have passed. Use your best judgment and if you still feel unsafe, then err on the side of caution and stay out of the water.
As mentioned above, there may still be residual effects left by the thunderstorm that can be hazardous. Always assess the conditions before deciding to swim again. Check for debris or other hazards in the water, and be aware that rip currents and other dangerous water conditions can persist for some time after a storm.
