Is these statements about temperature true?

[no idea]

Northern summers are hotter than southern summers.
Northern winters are colder than southern winters.

The Earth is closer to the Sun when it's summer in the south. I can't answer if this is the main reason the summer is hotter in the south though.

The earth is at aphelion - our farthest distance from the sun - in July, and perihelion - closest to the sun - in January.

Consequently, N Hemisphere winters are milder, and summers cooler, than those in the S Hemisphere. (In other words, those statements, No Idea, are the wrong way around :) )
