November 2017 Summary

An average November for both temperature and precipitation

After the warmth of the last two months we finally experienced some cooler temperatures.  Overall, November was about half a degree cooler than average, but still within the average range (the last time we saw a month that was in the below average range was April 2016).

However, if you take a look at the temperature graph you can see that the 10th and 11th really stand out as abnormally cold days.  The temperature went down suddenly for about 36 hours and then just as suddenly came back up.  In fact, if you took out those two days the month would have ended up being a bit above average.

Although the 66.2 mm of precipitation was well below the average of 87.1 mm this was just enough to put November into the average range.  So going into the final month of the year the total precipitation for the year is 956.6 mm which is above the average of 832.9 mm.  This also means that we are already above the average for the year of 916.3 mm, and would only need an average December to end up above average for 2017.

Summary for November 2017:
Maximum Temperature 15.8°C
Minimum Temperature -12.3°C
Average Daily High Temperature 6.2°C (Long term average 6.3°C)
Average Daily Low Temperature -2.3°C (Long term average -1.4°C)
Total Precipitation 66.2 mm (Long term average 87.1 mm)

(Long term averages based on 1981-2010 data for the Waterloo-Wellington Airport)
