I mean there is not a truly Mediterranean vibe in terms of climate, but there is some few Cfa influences, like Genoa, Italy.


The climate of Barcelona is characterized as follows:
There is a very low daily temperature range in every month of the year, which is lower than 8º C throughout the year.

There is a main rainy season during early autumn by few convective downpours, although most days use to be sunny and dry.
There is a secondary rainfall peak in spring season characterized by light to moderate showers well distributed in more days than autumn peak one.

There is a main dry season in summer, even though moderate to heavy convective showers by thunderstorms are not rare.
Then, there is a secondary dry season in winter as well.

The city often experiences strong temperature drops when northerlies in mid winter that makes it a relatively cold city by truly Mediterranean standards. In fact, from 1st to 7th February 2015, the average temperature measured 5º C.

Snow happens once or two every year in the neighborghoods that cover the hills near Collserola:

Winter frost often happens in the surroundings to the city when cold air is coming from inland to the coast by the mouth of the two rivers which border the city, just Besós in the north and Llobregat in the south (near the airport).

Summer tend to be too muggy with lots of tropical nights. On the other hand, highs hardly ever reach 30º C.
The city sometimes experiences heavy convective downpours during dry season. For instance, on 31th July 2002 there was more than 200 mm in three hours.

Thus, there are some oaks near Badalona, which are located very close to the sea.

The map posted above means that between those two black lines northweesterlies are lighter, which often implies that humid winds coming from the sea can spread away inland way better, and then summer thunderstorms are more likely.
So, in all those areas there are lots of forests, and not only Mediterranean ones, but some other like oaks, who are not typical Mediterranean trees at all.

It's just the opposite in those areas marked by red arrows, where gusty winds really turn the ground dry, so everything looks way more Mediterranean there.

I guess someone driving from Lyon, France, to Barcelone via Marseille, would notice how evertything looks dry all the way from Marseille to Figueres, then he would see how it changes to a beautiful mix of Mediterranean forest together with some few Eurosiberian forest.

Finally, if he continues driving away south to Tarragona, he would noticed how everything turns dry again like a real Mediterranean landscape.

I also made a thread about some Mediterranean cities NOT really having the Csa climate:

Would you consider these cities to be Mediterranean?

Is the dry season weak enough in summer that the vegetation stays close to green?

California, which has a strong summer dry season has oak forests. Though different from temperate oak trees found in the northern US or in England.

I have a bunch of photos, but it's hard to tell the tree. These might be oaks?

Believe me, CA has oak trees. The poison oak I always got hiking is testimony to that.

Poison oak is not an oak.

It goes against Cfa to say that it's driest in summer (as a season), and the lower diurnal range leans more towards being a Oceanic feature. The winter frost is of no importance.

It's just a marginal Mediterranean climate, leaning towards being a very warm Oceanic climate.

Barcelona's precipitations pattern is very similar to that of my city.
It is not "mediterranean" by definition and it belongs to the "humid subtropical" definition, but it's still more similar to other mediterranean cities than real humid subtropical climates that can be found in United States, China or Japan. Koppen put intermediate climates such this one in the large undefined pot of Cfa, which includes both Barcelona, Taipei and Orlando.
Now it's true that Barcelona hasn't a dry season, but grouping it with Tapei...doesn't work very well.
Taipei - Wikipedia, the free encyclopedia

There are many areas that are generally pictured as "mediterranean" but actually don't qualify according to Koppen: they aren't "extreme" mediterranean climates with summer drought and huge rainfall in winter: Catalonia (Barcelona, Tarragona), Provence (Arles, Nimes), Tuscany (Florence, Pisa, Siena, Grosseto), Abruzzo (Pescara), Apulia (Bari), Macedonia (Thessaloniki, Kavala).
On the contrary, Genoa qualifies as mediterranean thanks to its very rainy winter, despite summer is the same of Barcelona.
