That would actually be very uncommon. People talk about really hot,
humid weather like that a lot. "It was 110 degrees with 100%
humidity!" The example of 95F and 95% humidity would mean a
dew point of about 92. Last year a dew point reading of 88 was
recorded in MN, and that is one of the all time highest ever recorded
for the United States.
I grew up along I-95 and remember driving home from afternoon welding
class at NOVA in Alexandria and it coming to a stop at Springfield,
broiling in the 76 Scirocco with no AC.
In more relevant news, I'm about done with an initial prototype of a
window air scoop based on something I saw on the old Stan Wilder
website years ago. The AC on my '86 is not working and hasn't been
for several years awaiting an overhaul. I've always been
disappointed with the airflow in the van. It's like, I just can't
get enough to come inside! The low pressure area by the vent windows
and front windows is great for sucking air out, but there doesn't
seem to be enough overall exchange of air to prevent the heat from
really building up inside. My prototype is 1/4" (maybe
3/16"?) plywood cut to fit in the opening of the westy sliding
window on the passenger side. (Stan used plexi, and I will too if
this works well.) There's a hole cut in the board and affixed to the
outside of the hole is a 4" PVC "L." It's open end faces
forward. The board is cut to fit in the track such that it sinks
into the bottom track and slides into the front track, held there by
the window slid up against it's rear end. Quite secure on bottom and
front, and it has the screen behind it. My 1st test yesterday went
fine. It really did seem to blast in quite a bit of air at speeds of
40mph or higher, especially with the driver's vent or rollup window
opened to take advantage of that pressure drop. I just put some
additional adhesive on it and a coat of rattle can paint. I'm headed
toward Okeefenokee Swamp and Folkston Funnel in a couple days and
will likely get a good chance to test it in more serious heat than I
had yesterday.
