-15 is rare in the lower mainland. the average low in december and january is above 0.
i agree with you though snow in the lower mainland is worse. wet snow sucks, and it is only made worse by the fact that no one in the city knows how to drive in the snow. luckily though it is rarely there for any longer than 3 days. vancouver doesnt get winter, plain and simple, and i wish i was still living there. 1 week of crapty snow sure beats 5 months of negative tempuratures, remembering to plug in your car and getting out 20 minutes before you leave to start it up
