However, an upper limit of 30–50 miles (48–80 km) is more common due to topography, trees on the horizon, low to mid-level clouds, and the fact that local visibilities are generally no more than 25 miles (40 km).
How do you know it’s heat lightning?
The sky will seem to flicker with light; and even on a seemingly clear night with stars, you may see flashes. No sound accompanies the flash, although if you are listening to an AM radio, you’ll hear crackles of static at the same time you see the flash.
How far is heat lightning?

Is it safe to swim during heat lightning?
A: Swimming during a thunderstorm is one of the most dangerous things you can do. Lightning regularly strikes water, and since water conducts electricity, a nearby lightning strike could kill or injure you. To be really safe, you should not swim in an indoor pool when lightning is around.
What’s the difference between heat lightning and regular lightning?

How do you tell how far away lightning is?
If you count the number of seconds between the flash of lightning and the sound of thunder, and then divide by 5, you’ll get the distance in miles to the lightning: 5 seconds = 1 mile, 15 seconds = 3 miles, 0 seconds = very close. Keep in mind that you should be in a safe place while counting.
Is there ever thunder without lightning?
No, it is not possible to have thunder without lightning. Thunder starts as a shockwave from the explosively expanding lightning channel when a large current causes rapid heating.

Many people believe heat lightning is produced by hot and humid conditions, lighting up the night sky without any rain or thunder in the immediate area. This theory is completely false, and heat lightning does not actually exist.
Why does heat lightning have no thunder?
The movement of sound in the atmosphere depends on the properties of the air, such as temperature and density. Because temperature and density change with height, the sound of thunder is refracted through the troposphere. This refraction results in spaces through which the thunder does not propagate.
Has anyone ever died from lightning in a pool?
Lightning can also travel through any metal wires or bars in concrete walls or flooring.” So it sounds plausible that it could happen to you. But according to Aquatic Safety Research Group, “There are no documented reports of fatal lightning strikes at indoor swimming pools. None!Jul 12, 2017.

What are the four types of lightning?

What color is heat lightning?
A related term, heat lightning, is any lightning (IC or CG) or lightning-induced illumination that is too far away for the thunder to be heard. It may have reddish (“heat”) color, like sunsets, because of scattering of blue light.

Can you get struck by lightning in a tent?
Tents are often equipped with aluminum poles which resemble blunt-head LPS air terminals (lightning rods). If the tent stands higher than nearby objects or is under a tree, you could be at an increased risk of being struck by lightning or suffering exposure to sideflash or ground current—all which can be deadly.
How loud is lightning up close?
A clap of thunder typically registers at about 120 dB in close proximity to the ground stroke. This is 10 times louder than a garbage truck or pneumatic jackhammer drill. By comparison, sitting in front of speakers at a rock concert can expose you to a continuous 120+ dB level.
