Weather extremes
How extreme does Sierra Vista's weather get?
The hottest, coldest, wettest and snowiest days Sierra Vista 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 Sierra Vista has recorded — each shown against what a normal day that time of year looks like.
That is about 16°F hotter than a normal June afternoon in Sierra Vista (typical high near 94°F).

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.
Sierra Vista's record heat sits well above even a hot day for the season — June's 110°F is about 16°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.
