Weather extremes
How extreme does Gillette's weather get?
The hottest, coldest, wettest and snowiest days Gillette 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 Gillette has recorded — each shown against what a normal day that time of year looks like.
That is about 21°F hotter than a normal July afternoon in Gillette (typical high near 86°F).
The three most extreme on record
About 53°F colder than a normal December night in Gillette (typical low near 16°F).
The three most extreme on record
About 99% of a typical May's rain in a single day (Gillette averages roughly 3.3 in across the month).
The three most extreme on record
Close to a whole typical April's snow in one day (Gillette averages about 9 in across the month).

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.
Gillette'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.
