Nowra and Raleigh are the most subtropical of these in my estimation. I'd give the edge to Nowra overall as it's slightly warmer (about half a degree C) and, more importantly, has no dormancy period (every month has a 24 hr mean well above 10 C). But most of all, Raleigh has regular hard freezes that would be fatal to most subtropical plants (looks like they can expect to go below -10 C most years). But Nowra's record lows are barely below freezing.
But that's just my subjective view. Raleigh has significantly higher summer heat and humidity (mean summer dewpoints around 20 C versus about 15 C in Nowra). This gives the summers much more of a tropical feel, which some would say is more important to the "subtropicality" of a climate than a handful of cold nights per year.

Since Nowra's climate echoes Sydney's, I would have to say that this is somewhat untrue. Plants do go dormant here. And I don't mean leaf loss (deciduousness). Some evergreen plants do tend to "stop" growing in the winter, where they don't sprout any new leaves. And I mean just some species, especially the species that have winter dormancy. My native wisteria and Pandoreana, for example, were pretty dormant this winter. As if they froze in time. And now, in spring, they've just started growing new leaves. |

My native wisteria and Pandoreana, for example, were pretty dormant this winter. As if they froze in time. And now, in spring, they've just started growing new leaves. A quick look at the 5 coldest months for each location ( after all the subject is 'subtropicality', or in simple terms warmth ) Robbinsville - 5 coldest months means = 6.0c Goulburn - 5 coldest months means = 7.8c Raleigh - 5 coldest months means = 8.3c Nowra - 5 coldest months means = 13.8c Asheville - 5 coldest months means = 6.5c Braidwood - 5 coldest months means = 7.4c I will concede Nowra has a nominally subtropical climate, but can't see it for the other sites, no matter what happens in the 7 warmer months. Those 5 cooler/colder months don't cut it for 'subtropicality' in my view ( coming from a bloke who lives at 12.4*S, so might have a built in bias or 2..... ) As I've said previously, Aussies perhaps hold a a different perception of the term 'subtropical' Canberra - 5 coldest months means = 8.2c Armidale - 5 coldest months means = 8,2c Orange - 5 coldest months means = 6.9c Bathurst - 5 coldest months means = 7.9c Tamworth - 5 coldest months means = 11.5c Warwick - 5 coldest months means = 12.7c |

Robbinsville and Asheville are too cold to be subtropical (using a 5 C threshold). But the rest seem to fit the bill.

I would say Nowra and Raleigh are the solidly subtropical climates on this list. Raleigh just has more downwards variability in the cool season where the mean min temps and record lows are colder due to our continental nature, However, Raleigh has significant potential for some warm days in mid-winter (our mean max temp for Jan is 72'F).
I see people arguing the subtropicality of Nowra because the summers don't have super hot average temps in the summer but the summer doesn't have to be incredibly hot, or even have average high temps past lets say 86'F to be subtropical. Nowra's winters are quintessential subtropical for sure.

I'd say Nowra is the most subtropical.

I really hate to split hairs but Raleigh latitude is at 35.8'N (or 35.7796° N if you want to get specific) - I just noticed the latitude listed was 35.6'N - I mean it's close but just had to correct you brother, I'm sorry.

Fair enough...I'm a stats/data type bloke and like the numbers to be right as well. Small thing, but yep, its 35.8'N.  |

Nowra=Subtropical (cold month 6°C to 17.9°C, and 4+ months 18°C+)
Goulburn=Warm Oceanic (cold month 6°C to 17.9°C, and 3 or fewer months 18°C+)
Braidwood=Cool Oceanic (cold month 0°C to 5.9°C, and 3 or fewer months 18°C+)
Raleigh, Robbinsville and Asheville=
Temperate Transistional (cold month 0°C to 5.9°C, and 4+ months 18°C+)

Nowra's winters are quintessential subtropical for sure. My subtropical definitions are more in line with the old-school Cev myself haha; you're now a bit more lenient than I am. I'd say Raleigh and Nowra are indeed the two most subtropical climates of this bunch - but I'd consider both of them merely on the cusp as opposed to firmly within the zone. Raleigh's January mean of 5.5'C is very borderline IMO, though y'all's summers are indeed firmly subtropical. In the case of Nowra, it's the opposite: summers are the same as my location, and I think having a legit warm summer is just as important as having a mild winter for making a climate truly subtropical as opposed to merely a warmer variant of temperate oceanic. |

Robinsville, Raleigh, and Nowra can be classified as "subtropical" imo.

For me: Raleigh and Nowra are subtropical
