How Thunderstorms Affect the Internet

  • ADSL connections can be affected because cables found outside buildings are not well insulated

  • The saturation of the network that occurs on days with adverse weather phenomena is also one of the reasons that explains the poor connection

  • On hot days or when there is hail, the Internet connection can also be impaired

Weather conditions usually determine our mood and our performance. If it affects the human being, the climatic situation also affects technology. Surely you have noticed on occasion that, when it rains or the weather is bad, the WhatsApp message you just wrote takes longer than usual to reach the receiver. That’s because your Wi-Fi connection suffers for as long as it does.

One of the phenomena that causes the most slowdowns in the Internet signal is the electrical storm. Next, we will tell you the reasons that explain this impact on the network:

Reasons why the Internet is worse with a thunderstorm

First of all, about ADSL connections, it should be mentioned that phenomena such as rain or thunderstorms can have a negative effect on the Internet connection. Despite the fact that its installation is composed of a network of copper pair cables that are found in the subsoil and are isolated by air chambers, the derivations formed by the so-called lateral cables (which are what we see on the facades of buildings so that they reach homes) do not have an effective insulation.

Water and electricity are quite incompatible, which means that, if your connection is ADSL and it is raining or a storm is occurring, the signal slows down or it can even break down.

Second, the reason that can make the wifi work slower is network saturation. When a thunderstorm or other adverse weather phenomenon occurs, we are all usually covered in our house, so we spend our time connected to the Internet and that means that many more devices are being used and browsing the network at the same time.

There is routers that do not have enough capacity to cover these peak usage and the connection may be slower accordingly. However, over the years, these devices have been strengthened to prevent these problems from happening and that they are not oversized.

Ultimately, taking into account that what allows the diffusion of the Internet connection are radio waves that correspond to electromagnetic radiation, lightning from electrical storms in turn emit waves that can disrupt the spread of radio waves that facilitate the connection to the Internet.

If this occurs, it may cause the network operation to be inoperative in certain areas. However, it is less common for this to happen in those houses that have a router inside the home.

Other weather conditions, like heat, because an overheating of the Internet connection equipment makes the device work worse. It may also be that if hail falls in a very intense way, the connection is affected.
