What the joke would be is that with the -3C treshold Stockholm can be considered "oceanic". In reality it has a permanent snow cover for two or even four months, and that doesn't feel very oceanic.
What do you think of my subtropical threshold (a hybrid between Köppen and Trewartha?)
* All months above 2C
* If warmest month above 22C and coldest above 2C it passes.
* If warmest month above 20C and coldest above 6C it passes.
* If warmest month above 18C and coldest month above 10C it passes.
* If all months above 12C it's always a subtropical climate.
It's not bad. Still better than Koppen's, though.
*All months above 5C I'd say.
*I agree with 22C, except for 2C (I'd make it 5C)
*I agree with that one
*Hm...Not sure about this one.
*As above

A joke on your description of my Xmas book yesterday, but with my name inserted "damn Swede" etc...
Besides permanent snow cover here (colder than Stockholm due to no UHI) is normally three weeks-a month. It certainly feels very transitional. Each degree makes a massive difference.

Anyway, I think I'd lower the isotherm to 21C.
I tried to balance the summer and winter warmth when doing that one
If a climate has hot summers and cool winters with frequent frosts but with daytime temps below freezing rare (DC, Baltimore) I think it should be let off the continental hook
As for the fourth and fifth points would you prefer no lower isotherm for the maritime subtropical climates, so that they would have to have warm summers (excluding Auckland and A Coruña)?
The hottest month is pretty much irrelevant for a subtropical climate. The main thing is the number of months above 10C, who should be at least 7, preferrably 8.
The threshold dividing Dfa/Dfb should be lower. Place a like update New York have much more in common with places like Chicago, Detroit, Indianapolis, Toronto, etc. then places like southern Scandinavia, the Canadian prairies, southern Siberia etc.
I think 6-7 months over 10C--Dfa
4-5 months over 10C--Dfb
Because an 11C average minimum for a summer month, doesn't indicate a climate primarily under the influence of subtropical mass.

Fair enough. But, to be fair, the common threshold is 22C (71.6F) nowadays. I'm going with that. Heck, I think the mean subtropical threshold should be lower (21C at least), though winter higher at around 5C at most.
I don't have any thoughts on what the threshold should be, as I think a climate only needs to be primarily under subtropical influence to be subtropical. If you're going to use Koppen though, you should stick to it, so 72F it is.

Wait, I thought you ridiculed the fact that Wollongong is an oceanic climate and "more" in the likes of London than Sydney. Remember that one?
Nope - I probably said that in order for Wollongong to be Oceanic, it's climate would need to be more like London than Sydney, which isn't the case.

Why wouldn't those places be excluded, if they don't meet any required threshold?

They're subtropical under both Trewartha's and mine though...
