Weather extremes
How extreme does Grand Island's weather get?
The hottest, coldest, wettest and snowiest days Grand Island 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 Grand Island has recorded — each shown against what a normal day that time of year looks like.
That is about 15°F hotter than a normal July afternoon in Grand Island (typical high near 82°F).
The three most extreme on record
About 34°F colder than a normal January night in Grand Island (typical low near 19°F).
The three most extreme on record

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.
Grand Island's record heat sits well above even a hot day for the season — July's 97°F is about 15°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.
