So in an average winter (Dec, Jan, Feb), which city is more prone to cold snaps relative to their average temperatures Miami or Vancouver? Or put another way, which place has a higher standard deviation in temperatures for winter?
Here is some data to help you decide:
The best way of finding out is to scour the cities' respective data, by checking what their average annual lows are, and compare these to their normal daily lows. Ideally, you should aim for a 30-year period, but even 15 years would give you a good idea.
Avg montly mean temp std deviation in Miami for the three winter months is 1.7C(3F).
Avg montly mean temp std deviation in Vancouver for the three winter months is 1.7C.
They have the same exact monthly mean temp std deviation for the three coldest months.
The link you provided for Miami is not correct in the comparison with Vancouver. Enviro Canada gives the montly mean temp std deviation for Jan, Feb, etc. The link you gave for Miami that I saw gives the daily max and min std deviation. Can't compare the two without looking at the montly mean temp. Daily temps fluctuate more than monthly temps.
This is the link you need to compare Vancouver to Miami on montly std deviation.
Miami has more volatile swings in winter than anywhere in the immediate West Coast but even the coldest of cold snaps in Miami (48/27 F was the coldest day ever recorded) would feel warmer than a typical winter day in Vancouver (45/35 F under cold, overcast drizzle with a breeze) because of the clear skies, bright sunshine, and higher sun angle and lack of wind.
Besides, Miami would bounce back to about 60 the next day, 70 the day afterwards, and probably back close to their norms of 76/60 by the third day (beachable weather!) while Vancouver will be stuck with cold overcast until about June!
Does Vancouver get a breeze on a typical winter day? - I wouldn't have thought so, otherwise it wouldn't be as cloudy.
Winds here most of the year tend to be quite light except if there is a large storm coming. We get bad windstorms usually once every 3-5 years. The last one we had was at the end of August.

That's pathetic.
