Temperature: finer regular network -> conservative & smooth surface.

Hi, guys.
I have an average monthly temperatures in 25km regular network. I need to interpolate this data, making it smooth but conservative (with contours passing through as many as possible point values). Now my surface looks very sharp...
Do I need to use bilinear interpolation (or any other tool) to make my network finer and only then to interpolate my values?
Or I need something like radial basis function (with spline-tension kernel) / kernel smoothing interpolation method?
Any tips on this type of data would be appreciate.
