I think that the way it is "supposed" to be, from exf_fields.h, is:

c     All surface forcing fields are defined at the center of
c     each grid (the rVel location in model/inc/GRID.h) with
c     one exception.  When both ALLOW_BULKFORMULAE and
c     USE_EXF_INTERPOLATION are undefined, ustress and vstress are
c     defined at the Southwest C-grid U and V points, respectively.
