Abstract: The properties of the thermal Abelian monopoles are studied in the deconfinement phase of the $SU(2)$ gluodynamics. To remove effects of Gribov copies, the simulated annealing algorithm is applied to fix the maximally Abelian gauge. To study the monopole profile, we complete the first computations of excess of the nonabelian action density as a function of the distance from the center of the thermal Abelian monopole. We have found that, starting from distances of around two lattice spacings, the chromoelectric and chromomagnetic action densities created by the monopole are equal to each other, from which we conclude that the monopole is a dyon. Furthermore, we find that the chromoelectric and chromomagnetic fields decrease exponentially with increasing distance. These findings were confirmed for different temperatures in the range $T/{T}_{c}\ensuremath{\in}(1.5,4.8)$.
