Not sure what standards you intended to follow, but there no Convention 
attribute.

Default parser doesnt identify the month coordinate as time. You can fix like:

<?xml version="1.0" encoding="UTF-8"?>
<netcdf xmlns="http://www.unidata.ucar.edu/namespaces/netcdf/ncml-2.2"; 
location="D:/test/wells/30YrAvgMo.nc">
  <variable name="month">
    <attribute name="_CoordinateAxisType" value="Time" />
  </variable>
</netcdf>


( Better would be to use CF, and use climatological calendar, see section 4.4.1 
of here:

  http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.4/cf-conventions.html

but we have not yet implemented this. but if you are writing long-term 
archives, we should get on this.)
