Weather extremes

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.

Based on 18 years of daily weather observations (2005–2023), from the Peterborough Trent U station 6 km away. Updated through September 2023 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

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.

🔥 Hottest day
98°F Aug 1, 2006

That is about 19°F hotter than a normal August afternoon in Peterborough (typical high near 79°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.

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.

In plain terms

In a normal year, Peterborough's warmest days reach the low 80s°F and its coldest nights drop to the low 10s°F. But across the record it has gone as high as 98°F and as low as −27°F. A single day has delivered over 2 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
