The easiest way to do this would be to use a command-line utility from
one of the third-party packages that support netCDF data, such as NCO 
(or NCL or CDO).  For NCO, one of the averager tools ncea or ncra 
would be appropriate.  

There may also be a simple way to do this in MATLAB, but we don't have 
access to MATLAB here, so we are not familiar with it.
