Based off a shoutbox discussion where we were talking about the line that demarcates subtropical zones in various regions of the world such as Australia and the eastern US (usually tends to be around 35ΒΊ north or south of the equator).
However, the western US with all its mountain valleys is a little more debatable. You could easily make a case for Redding, CA being subtropical (40.5ΒΊN) (and a few would even argue Brookings, OR at 42ΒΊN). It could also be argued, however, that Redding is too high in latitude and gets too many cold fronts off the Gulf of Alaska to be subtropical, and that its weather systems are mostly temperate in nature, even if its temperature profile is closer to that of a subtropical climate.
That being said, where is the northernmost extent of western US subtropical climates?

I have difficulty calling any Mediterranean climate subtropical.
To me, tropical climates are defined by the convection of warm, humid air driven by diurnal heating. By extension, subtropical climates should have at least at least some of the year where this is a notable feature. Mediterranean climates lack this; their winter convection is linked to different mechanisms. Whence they are not subtropical no matter how warm they may be.
TL; DR: subtropical index has summer warm rain.

None. The west coast has no true subtropical climates, theyβre all variants of Mediterranean climates.
Now Iβd say a subtropical temp profile extends up to about Roseburg, OR at 43 N but thatβs a clear Mediterranean climate.

Now Iβd say a subtropical temp profile extends up to about Roseburg, OR at 43 N but thatβs a clear Mediterranean climate. Roseburg is incredibly warm/mild. The geography there is the main culprit, as any quick/easy pathway for cold air to advect to Roseburg just simply doesn't exist. Very specific setups are required there, in a region (western PNW) where specific setups are required for cold weather.  |

Redding, as it meets my requirements for the subtropical label:
β’ > 9 months with > 10Β° C means
β’ 12 months with > 10Β° C maxima
β’ > 6 months with > 20Β° C maxima
β’ Coldest month > 6Β° C in means (and of course > 10Β° C in maxima)
β’ Warmest month > 18Β° C in means
β’ Annual mean > 15Β° C
Redding is what I term, Mediterranean Subtropical (subtropical climate with a med precip pattern). Same type as Perth, but obviously a more continental variant.

Mediterranean climates are subtropical.

Mediterranean climates are subtropical. Interesting. Would you say that Eureka, California, is subtropical? |

Why don't you consider Mediterranean climates subtropical? Too me, subtropical means having tropical like weather in summer which humid and wettish. Mediterranean climates have summers resembling arid climates rather than tropical climates. So while they can have subtropical temps, I would consider them to be a different grouping. |

Tropical and subtropical are only describing temperature regimes in my opinion. There are dry tropical climates (Aden for example) as well as wet ones, and the same applies to subtropical climates.
