Small amounts of rain, wind, and snow should not impact your Internet connection. Large storms and high winds, however, are known to cause issues. High winds can knock down power and cable lines, freezing weather can destroy the existing copper lines underground, as well as cause issues for breakers, switches and other electromechanical components. Extreme heat can result in copper lines becoming frayed.Inclement weather can also indirectly affect Internet speed because if the weather is either uncomfortably hot or cold, people are more likely to stay inside and watch Netflix, play games, download music, etc. resulting in a server overload due to drastically increased usage in the area.
