How extreme does West Seneca's weather get?

The hottest, coldest, wettest and snowiest days West Seneca has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 50+ years of daily weather observations (1971–present), from the Buffalo station 12 km away. Updated through June 2026 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

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.

West Seneca's record heat sits well above even a hot day for the season — July's 98°F is about 18°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, West Seneca's warmest days reach the low 80s°F and its coldest nights drop to the high 10s°F. But across the record it has gone as high as 98°F and as low as −18°F. A single day has delivered over 5 inches of rain or close to 34 inches of snow. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
