Maybe, but if you're trying to appear folksy by using region-dependent seasonal identifiers rather than, you know, dates AND you're happy that instantly means 10% of your readers will be confounded by that, then I guess go for it.

I'll note that about 40% of the earth's population lives in the tropics, where seasons also don't break down the same way they do for the author - typically that demographic will recognise two identifiable seasons through the year.
