I am fortunate (and I know it) since in the morning I have either no wind or a mild tail-wind; in the afternoons I almost always have a decent tail-wind (off the ocean) heading east as the wind comes out of the west.
Okay, there have been exceptions to the above rule, but fortunately not very often.
When riding RAGBRAI several years ago I saw someone wearing a T-Shirt with the message "The Wind Doesn't Blow, it Sucks!" I rode some brutal all-day-long headwinds crossing Iowa.
