Hi, James.
This occurrence is normal when you use polynomials for fitting. The
simplest is to generate more points in the region of interest, i.e.,
use a finer sampling. Or, if you know the exact function describing
this "peak", you can fit it - FitFunction[], or use
FunctionInterpolation[]. Still, you can choose among different types
of polynomials
Method -> "Spline"/Method -> "Hermite", ...
but these are still polynomials.
