The temperature dependence of the dynamical evolution of rigid holographic bright solitons in photorefractive dissipative systems based on two-wave mixing is studies. Numerical results show that the stability of rigid holographic bright solitons in such systems depends strongly on the crystal temperature. The soliton formed at a given temperature can propagate stably in the crystal over a distance that is long enough. The input solitary beam can evolve into a stable soliton and propagate in the crystal when the temperature drift is quite small, whereasit will not evolve into a stable soliton and its intensity becomes increasing or decreasing with propagation if the temperature difference is large. A potential application of temperature properties of rigid holographic solitons in optical attenuators or repeaters is discussed.
