> (in the shade apparently, why?) Because the effect of the sun induces massive, extremely localized variations in apparent temperature. Are you wearing a black shirt or a white shirt? That changes apparent sun temperature. What is the color of the ground you're standing on? What is the material, for that matter? Note that all of these effects will only increase the temperature (during daytime, at least). The shade temperature is thus a good indicator of what the coolest possible outdoor environment will be.
