If you look at Julia[0] they have quite a lot of performance benchmarks and you will see that Fortran is always at or near the top. What is really important, from a numerical code point of view, is that with Fortran it is easy to be at the top by operating on matrices and vectors etc. You do not have to torture your mind and think too much to optimize your code, "remove the IF in the loops" is often just what you need. I am writing code in Fortran 77/90 every day, I really really enjoy it. Calling your Fortran code from Python is also so easy that you can really have clear cut between data management in Python and computational work in Fortran.
