A recent measurement of the optical conductivity in graphene [Gallagher, Yang, Lyu, Tian, Kou, Zhang, Watanabe, Taniguchi, and Wang, Science 364, 158 (2019)] offers a possibility of experimental determination of microscopic time scales describing scattering processes in the electronic fluid. In this paper, I report a theoretical calculation of the optical conductivity in graphene at arbitrary doping levels, within the whole ``hydrodynamic'' temperature range, and for arbitrary nonquantizing magnetic fields. The obtained results are in good agreement with the available experimental data.
