Does Weather Affect Cell Service?
Could rain, snow, or hot weather affect your cell phone signal?
Cellular network traffic is carried on radio waves, and so cell reception can be affected by any atmospheric condition that might similarly affect a terrestrial radio signal.
In fact, weather can have a direct or an indirect effect on 4G cell signal, but won’t really affect cell signals under 2GHz. An example of a direct effect would be a thunderstorm when lightning causes electrical interference with cell signals.
An indirect effect of weather on cell reception could be caused by a change of season, say from winter to spring.
For example, in a single-story home or office building surrounded by trees, this could mean better indoor cell reception in winter when bare trees are less of an obstacle to incoming and outgoing signals.
With the coming of spring, the surrounding trees bud out and then produce leaves. This increased foliage can diffuse, weaken, and even block cell signals traveling to and from the cell tower. Of course, this can negatively affect cell service for those inside the building, although not directly attributable to the weather conditions of the present day.
