We consider a non-autonomous two-dimensional Newton-Boussinesq equation with singularly oscillating external forces depending on a small parameter $ \varepsilon $. We prove the existence of the uniform attractor $ A^\varepsilon $ when the Prandtl number $ P_r>1 $. Furthermore, under suitable translation-compactness and divergence type condition assumptions on the external forces, we obtain the uniform (with respect to $ \varepsilon $) boundedness of the related uniform attractors $ A^\varepsilon $ as well as the convergence of the attractor $ A^\varepsilon $ to the attractor $ A^0 $ as $ \varepsilon\rightarrow 0^+ $.
