Making Average() formula ignore months with too much blanks

Hello everyone, I trying to make my Average() array formula ignore months, which have more than 5 blanks to simply ignore it, does anyone have a clue how to do this?
In the example that I show you, the second month should be excluded, because the values in column R have too much blank cells in that month.

P.S.
If using the blanks is too difficult, values in column N below 5 would respond in the same way (if there more than 5 cells with values less than "5").
