Comment(by hamish):
as long as it works and is understandable by you, I wouldn't be too
concerned with how elegant the outer loops are. that's not the
computationally expensive part.
if your map names are longer than ~10 chars in total, beware that the
maximum command line length may be 4096 chars on some OSs. so eg it may be
better to sum months to get the full year instead of summing up 365 maps
directly. (although if you can it might be interesting to compare results
of doing it both ways, in the past I'd gotten two slightly different
answers by doing that which confused me)
