My personal definition of a subtropical climate would be:

*Coldest month above 5C (e.g. Paris & London excluded, Tokyo, Hong Kong, Sydney, etc. included)
*Warmest month above 22C
*No dry season

So IMHO Sydney should "pass" the criteria, but barely, due to its coolish summers; so would Sochi (once again barely due to winters almost too cold to qualify); Shanghai would not and NYC would clearly not.

My definition of a subtropical climate is irrelevant just like everyone else.

All i'm saying is that if you want to classify San francisco as Subtropical Victoria should pass and i know there is a difference in winter temps but otherwise....

And i think because of the tropical isotherm is 18ºc i think 18 should be the subtropical isotherm but thats just my opinion

It's all in the look of a place to me. Many different palm species, bananas, avocados, a wide range of citrus etc, a big range of flowering plants during the coldest months. Lots of bee activity, and insects in general during the coldest months. Plenty of convective weather and cloud activity during winter- fair weather/towering cumulus.

Imo a climate needs these things to be subtropical. Exceptions can be made for otherwise warm climates, that experience infrequent killing frosts, but not for mild winter climates, that are generally to cold to support these things.

I don't see hot summers as essential. It should first be warm enough in winter.

Edit: On second thoughts - summer should be warm enough for summer vegetables.

Buenos aires is the perfect example of subtropical climate, it fits everyone criteria.

would Nice be subtropical?
what would be the difference between a subtropical and a mediterranean climate? the dry and wet season?

Absolutely! That would be the perfect example indeed, IMO.

Nope, Nice wouldn't; although temperatures fit perfectly, as you said, the big difference is in the rainfall patterns: July sees only 12mm of rainfall on average, and is almost completely dry most years (2mm this year), which is compensated by huge, once-in-the-month downpours once every few years (last year it rained 23mm in only a couple of hours) - conclusion is you can safely say that there is a very reliable dry season in Nice during summer, and that disqualifies it from the subtropical group.
But then again your are right, BA is "the" typical subtropical climate, with a winter average of 10.something°C, a summer average of 25°C and solid amounts of rainfall every month.

Joe90's description seems pretty much identical to a tropical landscape to me.

Really? So you wouldn't consider somewhere with a dry and sunny winter to be subtropical then (like southern or central Queensland)? I'm also surprised people don't consider mediterranean climates to be subtropical. I personally think rainfall shouldn't have anything to do whether a climate is classified as subtropical or not. Even desert climates that meet the temperature criteria should be labeled as a "subtropical desert climate", in my opinion.

So if you don't think subtropical climates should have a dry season, what sort of climate would you consider somewhere like Mackay to have?
