Comparison to recent months of DECEMBER at Alberniweather

MOST SIMILAR ALBERNIWEATHER DECEMBER TO THIS MONTH?  2011

December 2011 was quite similar with its cool temps, but it was a lot rainier. There was not a perfect match to December 2017 in my records. Maybe that just proves how special that Christmas Eve snow was!
