I will come with my family on Borovets (hotel Flora residence), on 27.January, for 7 nights.
I saw on some sites that the weather is going to change to very very cold (-10C). Does someone know more about forecast?
Believe me -10'C is nothing. Wait until you are on the mountain in an exposed area and you add the windchill factor to that -10'C and that will very easily become -20'C or colder.
Apparently my boss has just told me that depending on how much moisture in the air will depend on how cold it "feels" eg in Scotland it could be -2 and would feel really really cold, but in Bulgaria you could feel warm at this temp. I'm confused, must have been off that day at school!!
