There are two answers to this:

(1) Use double quotes instead of curlies:

#!/bin/csh -f
set title = "This is a title"
ncl year=2014 month=5 title=\""$title"\" myscript.ncl

(2) If you need this often, you may want to try a wrapper script for
ncl, called nclsh, (see gzipped attachment) which - if put in PATH - may
be called like ncl, but passes any command line options as NCL args,
creating quotes internally:

#!/bin/csh -f

set title = "This is a title"
nclsh --year=2014 --month=5 --title="$title" myscript.ncl
