How hot does it have to be to cook an egg in the sun?

According to the Library of Congress, it’s possible, but not probable, that you could fry an egg on a sidewalk during a hot day. Eggs need to reach a temperature of 158*F to cook through. Sidewalks can usually get up to 145*F. The hotter the day, the more likely your egg will fry.
