The explosion itself is not the source of the heat emitted from a nuclear detonation. Instead the heat is the source of the explosion. Compare this with thunder following a lightning strike. In the nuclear bomb temperatures of about 20 million degrees fahrenheit are produced causing the emission of x-rays which ionizes the air preventing any more light or IR emission until the bomb cools enough that it no longer is emitting x-rays. In lightning the temperature of the ionized conducting air channel is only about 90000 degrees fahrenheit.

As to the temperature of things around the fireball from a nuclear detonation, directly beneath the fireball temperatures can reach about 7000 degrees fahrenheit. To give an example by which to compare this heat, free flowing magma, or melted rock, averages a high of 4000 degrees fahrenheit.
