Climate (once again), Humidity

Another way to look at it, since I don't have a good measure for what
that means from a hard data perspective, is geographically.  If you are
in the US and live East of the Mississippi, you have at least a
seasonally humid, if not year round humid climate.  West of the
Mississippi is fairly uniformly dry until you get to the immediate
coastal areas. That coastal area being somewhat broader the further
north you travel and almost non existent if you go far enough South into
California on the west coast. 

If that is too vague, you may want to look at your typical dew points.
I would say of your dew points during the growing season are routinely
over 50F (and over 70f is no stranger) and you don't live somewhere that
temperatures often get over 100F you're in a reasonably moist area.

Here in the South East (US), my spring and fall dew points are usually
in the 50s and my air temperature is rarely over 75F.  Dew points in the
summer hover around 75F and my daytime highs are in the low 90s.  Here
we are bone dry in winter when it isn't raining, for the most part.
It's so humid that pressure treated decks that are treated annually with
weather sealant, rarely last 10 years without major repair.  Vinyl
siding mildews badly enough to require pressure washing once a year, and
any fabric or wood left in the shade has a nice coating of green algae
if it's been there more than a few weeks.  I think I'm humid:)

**I understand that 95% humidity at 95F is humid, but I am really 
interested in knowing what is a 'humid' climate. Where is the line 
drawn? When the books say something needs to grow in a humid climate, 
what is the definition?

**Yes, 95% and warm is a steambath.
On moist days here, even when we don't get above the 80's we think 
it's humid especially after working outside in it.
But, we're no spring chickens. :-(
