The hottest, coldest, wettest and snowiest days Trnava has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 15 years of daily weather observations (2010–present), from the Jaslovske Bohunice station 13 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Trnava
has recorded — each shown against what a normal day that time of year
looks like.

In plain terms
Across the record, Trnava has reached as high as 100°F and as low as 0°F. A single day has delivered over 3 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
