End of main Es season?

It is now early September, which the UK Met Office calls the start of autumn. Nights are starting  to draw in and the days are shorter. With another day with no signs here of Es on 6m and 10m, I think we are definitely at the end of the Es season in the Northern Hemisphere. Yes there will still be some Es but nothing like the scale in the summer. Today, only UK spots on 10m WSPR and 6m JT65. Let us hope the F2 this autumn is not too bad on 10m. I think tomorrow I shall switch to 10m JT65.
