Molecules of water are made up of an atom of oxygen and two atoms of hydrogen. They connected in an V-like shape, with the oxygen molecule at the bottom of the V. The hydrogen atoms are positive ions, meaning that they are essentially just protons, while the oxygen atom includes electrons. The bottom of the V has a slight negative charge because of the electrons, while the prongs of the V have slight positive charges because of the protons. That means that the prongs of one molecule are weakly attracted to the bottoms of other molecules. This creates a weak, mutable attraction between molecules, and gives them a weak tendency to want to stay close to one another. This gives water surface tension, makes it take longer to evaporate, and creates the "wet" sensation when water comes into contact with a solid.
Smart enough?

Acutally water is wet because its a liquid
its no longer wet when it becomes steam
(unless it condesates -> ie back to liquid)
it also isn't wet (technically) when its ice, its dry, however mostly when ice, the surroundings are hot enough to make the surface wet too...
so.. yeah water is wet because its liquid - this means its chemical properties give it a movable shape that - due to gravity falls across surfaces to fill the bottom of any container that it pours into...
as someone else suggested surface tension, I would like to mention that it seems more like a side-effect of having a "skin" at the top of the water... its how the molecules hold together exhibiting some what would otherwise be considered as unusal properties of its own
oh and soap, it makes water even wetter, by breaking down the hydrogen bonds between the water molecules...

Water is wet because of the molecular configuration of the water atoms. As you know, water is H2O, but what is important is that they are arranged asymmetrically.
O
/ \
H H
So, Even though the entire molecule is electrically neutral, there H side is slightly more positive than the O side. This slight difference is what gives to water its viscosity properties and also explains the surficial tension.
Most solids have also this slight charge difference at the surface (at the discontinuity) and are either slightly + or slightly - which will attract water molecules causing to be wet. A substance that is completely neutral at its surface (like Teflon) does not attract water molecules and it does not get wet.
Liquids like mercury do not get most objects wet for the same reason.
Now do your part. Compare the shape of a water drop in different objects.
Best regards.

All solvents wet to one degree or another. They are first broken into 2 groups - ionic and non ionic.
If I said "I shall not take a bath today the water is isnt wet enough" what am I saying? :)
Since temperature also affects wetting and solubility I might be saying the water is too cold.
;)

Water is wet because it is adhesive; it sticks to things.

Wet is just a feeling that your brain registers; if your brain isn't functioning properly, it might as well tell you that water is dry.

It has to do with surface tension, I think
