It was quite cool tonight;this is quite humid área.
The humidity is always 65% or more, unless there´s south wind that lets everything dry in hours.
I go always early morning and I come back with the outside of my shoes quite wet.It´s not a bad spot, south south/west orientation.
I have seen a Young oak like 50 m from the plants with powdery mildew no issues with that I think; more worried with mould.
Last year autum was quite dry, will see this year.
