After doing some quick research it looks like it is powdery mildew. I found some information below for you:

Signs of Powdery Mildew on Avocado Trees
Avocado powdery mildew is caused by a type of fungus called Oidium. The disease only affects the foliage of an avocado tree, not the fruit. However, if the infection goes untreated and becomes severe, it can weaken the tree. In general, powdery mildew is not considered a serious disease impacting avocado trees. You are most likely to see it during the drier months of the year. Signs that you may have powdery mildew will show on the leaves off your avocado tree. On younger leaves, look for darker green spots that are covered in a powdery substance. This is the fungus. On older leaves, the spots will become a brown or purple color with the powdery fungus. Eventually, the powdery substance disappears and brown, net-like markings are left behind on the underside of leaves with yellowish markings on the top of the leaves.

Treating Powdery Mildew on Avocado Trees
While it is not considered a serious infection on avocado trees, powdery mildew control and treatment is important for keeping your tree as healthy as possible. If you see any signs of the fungus, treat it immediately with an appropriate fungicide to eliminate and prevent it from spreading throughout the tree. Your local agricultural extension office or agrovet, can tell you what fungicide to use. Typically, a solution of sulfur is used for treating powdery mildew on avocados. Powdery mildew on avocado trees in your garden is nothing to be too worried about, but controlling infections like this is important for keeping your trees both healthy and attractive.
