I have heard the term heat index before
and wonder if someone could explain it to me. I am thinking it is the sum
when you add the air temperature and the humidity percent. Is this
true? And once you have this heat index number, then how do you use
it? What steps do you take with your riding the higher the number
is? And what number is the cut off for not riding at all?
Thanks,
Laura, where humidity is never much of a
factor out West, but heat sure is
