You're saving the entire workspace. Why don't you pass in some variable names (in single quotes) to save only what you really really need. How large are these variables? Hundreds of millions of bytes? Also, you forgot to tell us the exact error message or exact code, so I'm going to refer you to this: http://www.mathworks.com/matlabcentral/answers/6200-tutorial-how-to-ask-a-question-on-answers-and-get-a-fast-answer

Some versions of the save function really don't react well to structures.

MATLAB: Creating an array for Multiple variables

 yearno = 2005:2015;
 for mo = 1:12
   for yearidx = 1 : length(yearno)
     year = yearno(yearidx);
     [dttm{mo,yearidx}, timemin{mo,yearidx}, wnddatenum{mo,yearidx}, wndspeed{mo,yearidx}, wnddir{mo,yearidx}, pres{mo,yearidx}, temp{mo,yearidx}] = RdNCDCData(filename, mo, year, iminsamp);
   end
 end

Afterwards, to find a given year,

yearidx = find(yearno == 2009);    %for example

and then you can access the variables by month and yearidx

temp2009 = temp(:,find(yearno == 2009));     %would be all 12 months for 2009
