Es selectivity

So far today, I have had just spots from Austria on 10m WSPR and nothing at all on 8m FT8. 

Es can be very selective. Sometimes a station a few kilometres away spots a lot, whereas at your QTH there is nothing. Also, the openings can be widespread or in just one direction.

Although I may be factually wrong, my impression is openings to more northerly directions are more common later in the Es season. Southern stations are there, but the feeeling I get is that more northern stations are more frequent.
