Peterborough's weather extremes
The hottest, coldest, wettest and snowiest days Peterborough has recorded — the outer limits of what its weather can do. This station's daily record ended in 2023, so these are historical extremes from that period, not records updated to today.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Peterborough has recorded — each shown against what a normal day that time of year looks like.
That is about 19°F hotter than a normal August afternoon in Peterborough (typical high near 79°F).
The three most extreme on record
About 37°F colder than a normal February night in Peterborough (typical low near 10°F).
The three most extreme on record
About 91% of a typical January's rain in a single day (Peterborough averages roughly 2.6 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.
Peterborough's record heat sits well above even a hot day for the season — August's 98°F is about 19°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.
