No he's not.

13. Does humidity or being near a large water body affect on wind chill?

When we tested the new Wind Chill Temperature Index (WCTI), our researchers
applied the new index to 12 test subjects. The results of the tests showed
that relative humidity was an insignificant weather parameter, less than one
degree at worst. To simplify the calculation, relative humidity was left out
of the formula.

We did research a wet wind chill or blowing water spray. This research was
to simulate a person near a body of water or a mariner. These findings are
being finalized and may be incorporated for the winter season 2003-2004.
