Weather extremes
How extreme does Penticton's weather get?
The hottest, coldest, wettest and snowiest days Penticton has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Penticton has recorded — each shown against what a normal day that time of year looks like.
That is about 37°F hotter than a normal June afternoon in Penticton (typical high near 75°F).
The three most extreme on record
About 49°F colder than a normal December night in Penticton (typical low near 22°F).
The three most extreme on record
More rain in a single day than Penticton usually gets in the whole month of August (typical August total about 0.4 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.
Penticton's record heat sits well above even a hot day for the season — June's 112°F is about 37°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.
