Weather can have a negative effect on cellular radio waves, thereby affecting mobile signals. A thunderstorm could damage adjacent cell sites, but how do certain conditions affect radio waves from being transmitted from your mobile device to the tower?

Direct Impacts Of Weather On Cellular Signals

  1. Lightning that emerges from thunderstorms results in power interference.
  2. When the airborne water molecule level is high, it can send back the electromagnetic waves and change their direction. As a result of it, the signals will possibly become spottier.

Indirect Impacts

  1. Tree leaves obstruct, diffuse or compromise both inward and outward signals in the summertime.
  2. Speedy winds damage the primary cell site both structurally and electrically.

There are more examples to give you than the ones mentioned above. Anyhow, without further ado, let us take a look at the possible effects of each weather condition on the signal.

Snow And Hail

It is believed that snow has no direct effect on it. However, if snowfall results in issues such as an outage, or more load on cellular towers, then it could affect the signal. When more individuals are stuck inside their buildings, the use of mobile phones will increase. This could then put such a strain on the towers that it negatively affects cellular performance.

Hailstones and snowflakes comprise ice that is less reflective and dense as compared to water, so these will not likely change the direction of the electromagnetic waves. Heavy snowfall does not usually cause signal issues, but sometimes it could.


A thunderstorm or rainstorm is the weather condition likeliest to have a negative impact on cellular reception. A large number of drops of rain could bring about negative variations in the signal. So when downpour gets heavier, the chance of your reception being affected will also go up.

Water Vapor In The Air

The atmospheric vapor can be in the form of fog, rain, snow, and humidity. It can impede or spread out radio waves, which then possibly brings about poor cellular reception. The process of the water-conducting electricity can refract and/or reflect radio waves too. Water can absorb energy from these electromagnetic waves and then turn it into heat, resulting in propagation delay.

How Water Vapor Makes Cellular Signal Weaker

It takes more time for the cellular signal to transmit between cell sites, and the signal would appear on a mobile device as reduced reception, intermittent, or zero reception. The existence of some atmospheric moisture could make signal transmission easier. Conversely, excessive moisture can be an interference.

Fog And Clouds

Both are a mass of water vapor in the atmosphere, so these might refract radio waves, thereby impacting cellular signals. However, this does not always happen. Some individuals get better cellular service in foggy days. Water vapor could make the existing signal better provided that the latter is not extremely strong.

Other Conditions


There is no evidence that every form of strong wind has a direct effect on cellular signals. It can come in the forms of a squall, gale, breeze, hurricane, and storm. Now, could all of these types of winds indirectly affect it? Yes. Speedy winds could damage adjacent cell sites and electrical lines, which may then cause reduced signals. Then again, it is important to note that it is an indirect effect of the weather condition.


Excessively hot or cold weather conditions usually have no impact on cellular signals. The factor that would cause the issue is variations in water vapor in the atmosphere. When the weather is too hot, such as in a desert, or extremely cold, the vapor fades away or freezes. As a result, enough amount of it does not exist in the atmosphere to facilitate the electromagnetic waves, but this will possibly not affect the signal considerably.

Solar Flares

A solar flare could bring about variations in cellular reception too. This event may interfere with the usual functioning of electronic communication devices such as mobile phones, and it may indirectly make the reception patchy.

In What Way Can You Overcome Cellular Signal Issues

In the event of cellular coverage dropping when there is a weather phenomenon in the area of your house, you might wonder how to boost mobile signal. A good solution may be a cell phone signal booster. It may help you to successfully deal with the effects that inclement weather has on the cellular signal. This product does not create a signal. Rather, it takes the signal available outside a building and boosts it to provide you with a better and more reliable output.

This increase in the strength of the signal may help you to telephone with better clarity and browse the web quicker. The increase is generally referred to as the ‘gain’ of the signal booster.
