That area is in shade then the heat that is effecting the area is coming via breeze or it is reflected heat not direct from sun. If you like the observation then you need a windbreak to modify the ecology. Trellis and vine can be along where the reflected heat is coming from which in photograph one seems the wall. Huge wall and if it is yours then a few Rose/Bougainvillea ramblers/vines will would give a dramatic effect.
Again in photograph one I see a gap between the house and the wall, either the hot breeze is entering or exiting from there. Some modification is required there also. Maybe a few small fruit trees if that area has sun and if not then some shade loving tall bushes and a few small shade loving trees should break the force plus further cool down the area.
I also see three lanky scraggly trees there. How about some tree surgery/pruning to make them a bit lower and more bushy. Maybe dig around their base and mix in a bit of organic fertilizer.
This Eriobotrya japonica due to little sun will go tall, lanky and snap in strong wind. Not much fruit either. Could you shift it along the wall. Let it enjoy the reflected heat. Loves heat.
Just observations and rambling.

Arif.
