It is very hard to provide an useful insight without seeing the context. What is the rest of the tree like? Where are the infected leaves? Which part of the tree
Provide some context about water and weather. Also, could it be damage from someone using herbicides near by?

I doubt it is viral. Are you seeing any insect vectors on the plants. That is a wide range of temps but how often has it been close to 40c. I suggest this is heat stress. Label the infected leaves and see which new become affected. Also, check for insect vectors

David Hughes commented,
if it is viral there is no cure. The best you can do is remove vectors. But I would suggest it is hit stress
