Wet or Damp Location?

From the National Electric Code
Dry Locations:
A location not normally subject to dampness or wetness.
A location classified as dry may be temporarily subject to
dampness or wetness, as in the case of a building under
Damp Location:
Locations protected from weather and not subject to
saturation with water or other liquids but subject to
moderate degrees of moisture. Examples of such locations
include partially protected locations under canopies,
marquees, roofed pen porches, and like locations, and
interior locations subject to moderated degrees of moisture,
such as basements, some barns, and some cold storage
Wet Locations:
Installations underground or in concrete slabs or masonry in
direct contact with the earth; in locations subject to saturation
with water or other liquids, such as vehicle washing areas;
and in unprotected locations exposed to weather.
From UL Standard Publication 1598
Dry Locations:
A location not normally subject to dampness, but may include
a location subject to temporary dampness, as in the case of a
building under construction, provided ventilation is adequate
to prevent an accumulation of moisture.
Damp Location:
An exterior or interior location that is normally or periodically
subject to condensation of moisture in, on, or adjacent to,
electrical equipment, and includes partially protected locations.
Wet Locations:
A location in which water or other liquid can drip, splash,
or flow on or against electrical equipment.
A wet location luminaire shall be constructed to prevent the
accumulation of water on live parts, electrical components,
or conductors not identified for use in contact with wate .
A luminaire that permits water to enter the luminaire (during the
rain test of Clause 16.5.2 or the sprinkler test of Clause 16.5.3)
shall be provided with a drain hole (Clause 13.4.3).
So, would the lights under this sloped soffit/eave considered a "wet" or "damp" location?

I would say a damp area regarding any fixture choices.
