[re Vancouver]

One factor may be that their northerlies will be considerably colder
than ours, since IIRC the orientation of the coast is such that winds
from that direction will have had a long land track (and before that
probably over Arctic Ocean ice).


I think it is the influence of ocean currents. Because the Pacific is
so much larger than the Atlantic, its eastern boundary current is
cold. *Seehttp://www.kidsgeo.com/images/ocean-current.jpg


Cheers, Alastair.


This map on Wikipedia tells a rather different story:

It suggests that Vancouver would benefit from the relatively warm Alaska
Current. See also:

http://en.wikipedia.org/wiki/Alaska_Current


Note that it is relatively warm! The Wikipedia entry states "Alaska
Current water is characterized by temperatures above 39°F (4°C)"


True, but I imagine that would be its temperature by the time it had
reached the Gulf of Alaska, and that it would still be several degrees
warmer off Vancouver.
