Although Portsmouth is quite close to a csb.. pretty much the only place in the UK close to anything other than cfb.

Some years we can be csa,csb, or cfa

Portsmouth has defo had a csb like climate this year! That's not that rare. Think the last time we had a csa may have been in 2006, but a csa climate like year is very rare, (around every 5 years). cfa, not sure if I can remember this kinda climate in Britain before? In general though I would say we're mostly oceanic and we are controlled by the sea climate wise. You know Melbourne is considered an oceanic climate, you'd think it's more of a csb wouldn't you?

Yeah but I thought Koppen, which classifies Washington DC as humid subtropical, is crap? What does Trewartha say about Portsmouth?

Would you mind posting your monthly averages. You say your climate is humid subtropical, I would like to see the data. People go beserk when the same is said about Washington DC using Koppen.

The data on wiki looks like crap as it is not from a national weather service. I have climvis data from NOAA that list your averages from 1981-2010 as

Dec 44.9/33.3F
Jan 43.4/30.9F
Feb 48.6/32.7


If these are close to being correct, your climate average mean temp for the three winter months is 39F. And Washington DC is 38.2F.



What are your national weather service averages from the airport and not the middle of the city?

In all fairness, Portsmouth does have characteristics of a cool summer Mediterranean climate. It has a clear trend of drier summers which are close to 3x drier than the wettest month in July. It also has winters that are only 2C or 3C cooler than Nice and summers with around 250 hours of sunshine in each month. It definitely has some cool-summer Mediterranean characteristics.

Washington on the other hand features lows below freezing, sees snow each winter pretty regularly, there is no comparison here. You can argue that the word 'subtropical' is the issue, but it isn't just that. Washington as a cfa climate by definition is nowhere near the climate of say Brisbane, they are just totally different. Even climates in the middle of the cfa spectrum hold no similarity.

Bologna has a Cfa climate. Here you have the averages for Bologna airport 1971-2000:
Stazione meteorologica di Bologna Borgo Panigale - Wikipedia

Washington DC seems an extra continental version of Bologna, with hotter summers and much colder winter extremes.

I would be very reluctant to say a climate is humid subtropical if any month's average low is below freezing

And extremes are not used in any way to define a climate in Koppen.



I find it a little hypocritical that many Europeans jump all over the idea of DC being identified as subtropical by Koppen, and yet your city has a month with an avg low temp below freezing (I've heard people from Europe say no way if one month is below freezing on the low). The fact remains, on averages your climate is barely warmer than DC in winter, and is cooler on annual mean.
