Weather extremes
How extreme does Chatham's weather get?
The hottest, coldest, wettest and snowiest days Chatham 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 Chatham 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 Chatham (typical high near 81°F).
The three most extreme on record
About 41°F colder than a normal February night in Chatham (typical low near 16°F).
The three most extreme on record
About 88% of a typical July's rain in a single day (Chatham averages roughly 3.4 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.
Chatham's record heat sits well above even a hot day for the season — July's 96°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.
