It also makes a huge difference if the wires are stranded or solid due to "skin effect". All distribution wiring is solid while patch cords are stranded. It all depends on what type of signal is in the cable.
F-, mr computer guy, sit down.
With lower temperature, resistance of cable is reduced and velocity of propagation is increased (speed of electric field propagation, and speed of current as a consequence).
Air temperature has negligent effect on 900MHz/1.8/1.9/2.4/5 GHz radio your wireless modem has, but precipitation does.
