No, it makes things worse in humid climates.

Interested. Would evaporative cooling work _at all_ in humid climates?
Perhaps with some modifications? I think not but haven't tried.
Sleepbreeze.com.uk <http://Sleepbreeze.com.uk> does seem to work, but
that's one body, not one room.
Thanks,

David is right. You definitely need to have an exhaust vent. Swamp
cooling cools by moisture evaporating in dry air -- not by
creating increasingly swampy air. You must draw fresh dry air in,
and let the moist air out.
Since the moist, cooler air falls to the floor, it is best not to
depend upon a roof exhaust vent. A mid-height window, or open
door will do the trick.
RE: your test. You didn't tell us WHERE, what region, you were
conducting the test in. Were you in a region with 30% or less
relative humidity? If so, your test would be a good indicator of
the effectiveness of the evaporative cooling, once you have the
intake and exhaust set up correctly. If you were in a higher
humidity zone, there is no point in running the test. It simply
won't give you any indication of how the evaporative cooling will
work in low-humidity, desert conditions.
Hope that helps.
