Trees create a cooling effect past shading the area. It’s a combination of shade and evaporative cooling.
Trees will shade far more surface area than just a window. I’ve got 9 around my house. They block direct sun through the windows all summer. While not blocking any light in the winter. They also keep the siding and sections of the roof cool.
