Thanks again, Bernie.
I poked around the web after writing and found quite a bit of data -mostly
about fisheries along the North American west coast. The annual variations

background expertise than I can apply.
For the casually interested, this was a useful, albeit short, read:

... particularly the paragraphs about rising winter temperatures which
I've definitely experienced over my 15 years in this location.
There's nothing quite like a brisk -35=B0C week or two to clear the nostril=

and hold the bark beetles at bay --seems to be a thing of the past.
I feel safe in betting on August ;)
