The air around a lightning strike is about 54,000° Fahrenheit (30,000° Celsius), which is six times hotter than the surface of the sun. The reason it is hot is because it is an atmospheric discharge of electricity. How lightning initially forms is up for debate between most weather experts and meteorologists. Lightning can also form around volcanic eruptions.

Lightning is a discharge of electricity through a very poor conductor (air). The resistive effect of this poor conductor causes heat. It is the same as how a coil in an electric heater works. The coil is resistive to the electricity and produces heat. The filament in a light bulb is resistive and produces light as well as heat. The power comes from the tremendous amount of charged (negative to positive) particles being conducted through this electrical path.
