Light does not have mass; this topic has been covered
in quite a few Mad Scientist questions already. See
or do a MadSci
search on
'photon mass'.
You don't weigh more on a sunny day because your weight is
the force that the Earth exerts on you due to gravity. This
doesn't change with the weather (even though we may talk about
the air feeling 'heavy'!)
