The tempreture at the center of a nuclear explosion depends on the yield of the weapon. Or whether the weapon is an atom bomb which relies on nuclear fission to detonate or a hydrogen bomb which uses both fusion and fission. Those are all factors that play a role in the temperature at the center of a nuke but the temperature at the core of the explosion is always between 50 and 150 million degrees Fahrenheit. any person around the point of which the bomb was detonated, would literally be instantly vaporized to nothing, its also odd because you either vaporize to nothing or in some cases get petrified. that's why sometimes the temperature of a nuclear weapon is referred to as the black body temperature, because there were cases in which peoples bodies were turned black like charcoal and hard as a rock. So the temperature of the center of a nuclear bomb can reach temperatures hotter than the core of our sun. the sun reaches nuclear fusion through gravity and so burns at a mere 15 million degrees Fahrenheit, on the other hand a thermonuclear bomb, once detonated can only have a significant reaction rate only if it has a far higher temperature (as much as ten times higher than the sun) because it has to occur where the air pressure is very low.
The whole world is setting new record temperatures every
day/night. The GPNW has recorded most days over
90 degrees..ever 12 and atleast 2-more before a cool
down as we get above the jet-stream. Just the 1st August
and for sure we add to the total. Iran having some summer
weather you hope like hell you never expierence.

How hot is a nuclear explosion?
