It was another warm month at an incredible 3.6 degrees higher than average. You have to go back to October of 2007 to find a month that was this much above average. As well, it was the warmest November since 2001 and the 5th warmest since records began in the region (the warmest was 1931 at 4.3 degrees above average).
Up until the last couple of days of the month it was looking like a dry month, however an amazing 51 mm on the 29th put us in the above average range. The final total was 106.6 mm compared to an average of 82.3 mm.
There has now been 1047.6 mm of precipitation this year, well over the average of 932.9 mm and the third most ever recorded for the end of November. However, we will have to get over 140 mm in December to beat the all time annual record.
Summary for November 2011:
Maximum Temperature 17.7°C
Minimum Temperature -4.6°C
Average Daily High Temperature 9.8°C (Long term average 5.6°C)
Average Daily Low Temperature 1.6°C (Long term average -1.6°C)
Total Precipitation 106.6 mm (Long term average 82.3 mm)
(Long term averages based on 1971-2000 data for the Waterloo Wellington Airport)

Global Warming...
was any snow recorded?
Our autumn has been consistently above average of late. The last three November's barely recorded any snow. Now, if only it was true for spring as well...
May I know where you get the long-term averages? Are they the newly computed 1981-2010 averages?
A bit late answering these:
Re: Global warming...
I always say that one particular month or even one season is too short a time to attribute anything to climate change. However the more we see the anticipated pattern of future climate change in the current readings the more it is looking that way.
Re: was any snow recorded?
We only got a trace of snow one day at our measurement sites.
Re: long-term averages.
As stated at the bottom of each summary they are currently the 1971-2000 averages. Once Environment Canada changes to 1981-2010 as their standard we will change as well.
