Well, yes, that would be something to see.  I predict that this will
show up in a SotM presentation, or on a third-party web service before
it is adopted, if ever, for osm.org.

One problem that would arise for anybody offering this service, is
that users will be tempted to reload often to see the current tide, to
just watch the water go up and down.  So you'll serve many more tiles
per user than a "typical" tile set.  Now, if you could render the
tides in the client, by fetching real time depth data, or by loading a
tide chart separately, ...
