Trieste's weather extremes
The hottest, coldest, wettest and snowiest days Trieste 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 Trieste has recorded — each shown against what a normal day that time of year looks like.
That is about 17°F hotter than a normal August afternoon in Trieste (typical high near 85°F).

About 26°F colder than a normal December night in Trieste (typical low near 33°F).
The three most extreme on record
More rain in a single day than Trieste usually gets in the whole month of September (typical September total about 6.9 in).

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.
Trieste's record heat sits well above even a hot day for the season — August's 102°F is about 17°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.
