Why does your skin give off more heat when you have sunburn?

When sunburned skin looks pink or red, it's not because the skin's surface itself is burned, but because blood has concentrated in that area to repair and replace skin cells damaged by UV radiation. That concentration of blood just below the skin's surface is also what causes it to feel warm to the touch.
