In the distance, you witness lightning but hear no accompanying thunder. Could it be a glitch in the matrix? Not exactly. What you observed is commonly known as heat lightning. However, the truth is that heat lightning is not a real phenomenon. What you’re really witnessing is regular lightning occurring at such a distance that the sound of the thunder doesn’t reach your location. The term “heat lightning” is often used because distant thunderstorms are more prevalent during the summer months, and people are typically outdoors in warmer weather conditions to witness this occurrence.
There’s nothing particularly unique about heat lightning. As someone who has lived in Florida near the Gulf Coast, I frequently encountered so-called heat lightning during the evenings. Thunderstorms often occur on the Atlantic coast or in the Atlantic Ocean, over 100 miles away, making it impossible for me to hear the thunder. Those closer to the storm, however, would be able to hear the thunder.
Heat lightning poses minimal risk as it usually occurs many miles away from where you are situated. Nevertheless, storms can shift and move closer to your location, so if you do hear thunder, it is essential to seek shelter indoors. Additionally, factors such as mountains, hills, or dense foliage can dampen the sound of thunder. The atmosphere itself can also impact the transmission of sound, with phenomena like warm air aloft (inversion) potentially carrying soundwaves from thunder further than usual.
