“As is typical of December it was an eventful month as numerous Pacific systems pushed across southern BC,” wrote forecasters Ron Lakeman and Jesse Ellis in their monthly roundup of statistics.
The first half of the month was relatively mild and especially wet, with 112.6 mm of rain and wet snow recorded in the first 12 days. However, even with the almost 35 cm of snow that fell during that period, there was only a trace of snow on the ground by mid-month. A record daily high temperature of 10.5 degrees was set on the 9th. The coldest temperature was minus-8.9 degrees on the 17th.
In the second half of the month, temperatures were cooler and snow was still frequent but much lighter. The greatest daily amount was 11.6 cm on the 20th. The local snowpack was measured at 15 cm on New Year’s Eve.
The record for the most precipitation in December is 195.1 mm, set in 1996, of which 169.5 mm fell as snow. The driest year on record was 19.9 mm in 1985.
The warmest temperature ever recorded in December was 11.6 degrees on Dec. 27, 1980 and the coldest temperature was minus-30.6 on Dec. 30, 1968.
