Cerknica's weather extremes
The hottest, coldest, wettest and snowiest days Cerknica has recorded — the outer limits of what its weather can do. This station's daily record ended in 2023, so these are historical extremes from that period, not records updated to today.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Cerknica has recorded — each shown against what a normal day that time of year looks like.
That is about 21°F hotter than a normal August afternoon in Cerknica (typical high near 76°F).
The three most extreme on record
About 50°F colder than a normal January night in Cerknica (typical low near 23°F).
The three most extreme on record
About 85% of a typical November's rain in a single day (Cerknica averages roughly 6.6 in across the month).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Cerknica's record heat sits well above even a hot day for the season — August's 97°F is about 21°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

Methodology & sources
Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Postojna, a weather station, about 13 km from the city centre. The underlying daily records come from NOAA's global station network.
