I am saying that I have been to Pamporovo for the last 18 years and until 4 years ago the real snow arrived early to mid January, but over the past few years it has moved about 4 weeks.
Ask anybody who has been early Jan recently.
March last year was fantastic and I would expect that again this year.
Fact seems to be that the Pamps season is getting shorter and shorter as by the end of March/early April the temps rise and the days become much sunnier,a problem caused by its southerly position
