Weather extremes

How extreme does Banja Luka's weather get?

The hottest, coldest, wettest and snowiest days Banja Luka has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 25 years of daily weather observations (2001–present), from the Banja Luka station. Updated through May 2026 — 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 Banja Luka has recorded — each shown against what a normal day that time of year looks like.

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.

Banja Luka's record heat sits well above even a hot day for the season — July's 107°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.

In plain terms

In a normal year, Banja Luka's warmest days reach the high 80s°F and its coldest nights drop to the high 20s°F. But across the record it has gone as high as 107°F and as low as −9°F. A single day has delivered over 12 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
Methodology & sources

Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.

Precipitation — 1991–2020 normals computed from 12 years of daily observations at Banja Luka, a weather station, inside the city. The underlying daily records come from NOAA's global station network.
