30 Sep 2018 – Last night, “he cold pole was minus 7.9, so a new record of the cold of September came,

but if there was no fog, it would even have minus 11,” wrote meteorologist Arnold Jakubczyk on Twitter.

In the night from Saturday to Sunday the cold record for this month fell in the Czarny Dunajec to minus 7.9 degrees.

“Black Dunajec today was -5.8 at 2 m and – 9.2 at the ground.” Normally a shock, because the record was broken in September,” he reports.

On the night of 25/26 September 2018 the lowest temperature was measured at Kasprowy Wierch – minus 6.6 degrees.
