Precipitation-wise, it really depended where you were in British Columbia whether or not you had a wet December or January.
The south coast had a very dry December followed by a somewhat dry January. On average, December at Vancouver airport records roughly 162 mm of precipitation (rain and snow combined). This December, the airport only picked up about 77 mm; about half the normal amount.
January was a bit wetter in Vancouver recording about 142 mm of precipitation with the normal amount being about 168 mm (80% of normal).
If you look at central and northern coastal sections of B.C., though, December was very wet. Prince Rupert picked up 370 mm of precipitation in December with the climate normal being about 294 mm. January was on the drier side with 106 mm recorded compared to the normal 276 mm. January did end off on a foggy note for many southern B.C. residents.
