are black holes super cold?

My thought was black holes are so powerful that nothing escapes so they must be very cold. 

Secondly if some heat escapes does  escape does that mean the area around a black hole is Super hot?

Thank you for your answers.

The temperature of a black hole (due to Hawking radiation) depends on its mass: the more massive it is, the colder it appears to be. Astrophysical black holes are quite cold; a black hole with 5 times the mass of the Sun is about 10^-8 K, meaning that radiation is entirely undetectable. Tiny black holes that could conceivably be created by high energy cosmic ray collisions would be much hotter and evaporate very quickly.
