November 2025 Summary

The second snowiest November with average temperature and precipitation

It was never really warm or very cold during November, although there were a couple of cooler spells that resulted in the average for the month being 0.7 degrees below average (but this is within the average range).

A large snowfall at the end of the month brought the total precipitation up to 82.4 mm, not too far above the average of 71.9 mm.  However, it was still the second wettest November in the past decade.  The total precipitation for the year of 830.0 mm is just a whisker below the average of 832.9 mm.  

Not only did we have a very early first snowfall on Nov 9, but also over 30 cm on Nov 28.  This put the total for the month at 59 cm, well above the average of 11 cm and more than any November snowfall in recent history.  The only November I could find with more was way back in 1950 when they had 105.4 cm, including an impressive 61 cm on Nov 24.

Summary for November 2025:

Maximum Temperature 13.4°C
Minimum Temperature -6.6°C
Average Daily High Temperature 6.3°C (Long term average 7.2°C)
Average Daily Low Temperature -1.2°C (Long term average -0.8°C)
Total Precipitation 82.4 mm (Long term average 71.9 mm)

(Long term averages based on 1998-2024 data from the Soulis Memorial Weather Station at the University of Waterloo)

Are the instruments that measure precipitation temperature etc. working? I have tried to check after heavy rainfall and snowfall and the instruments say zero.

To the user above, I agree. For me, too, the instruments say zero. Also, for the March 4 2023 snowstorm, that winter's data for that day shows 0 cm of snow during that snowstorm. That's a huge error. I wonder why the data is missing considering Kitchener got 25 cm? Reports say Waterloo got 27 cm. That's why it's hard to believe anything anymore considering the discrepancies that abound.

The 61 cm of snow recorded on 24-Nov-1950 at the relatively nearby (and closed) Kitchener weather station is the largest 1 day snowfall on record for this area. That snowstorm produced large amounts across a good part of southern Ontario and neighbouring states.
