Perhaps I should have been clearer with the title with this thread... I really meant Oceanic (Cfb) climates and not climates with some oceanic influence.

If you're using Koppen's classification, there's nothing to debate. The definitions are a given, you could think they should be something else; but then you're creating another classification system

I thought your original question was perfectly clear. The answer is that yes, Cfb climates can have a bit of snow cover from time-to-time. However, snow cover is not ever the norm for winter.

All this is self-evident. The problem arises when people inappropriately conflate a bit of temporary snow cover with an entrenched months-long snow pack. These are two totally different scenarios and result in two fundamentally different climates.

The other problem arises when people think oceanic influence equates to a Cfb climate. Most climates have some or even a lot of oceanic influence; that doesn't mean they're all compelled to be labeled Cfb or even prefixed with an "oceanic" qualifier. Longyearbyen is warm for latitude because of a far-away ocean but its winters are in no way Oceanic or even oceanic.

Oceanic implies a range within the Koppen classification: therefore some will be snow free (or even close to frostproof) while others will get a significant number of snow cover days. It's just like how both San Francisco and Rome are both considered Mediterranean while being drastically different in seasonality and overall feel.

Sure, but snow will never be the dominant pattern in winter. If it is the dominant pattern then it's not Oceanic.

It would alternate between cold rain and snow but snow can dominate during colder segments of winter in borderline places such as this:

Juneau is borderline though; as such it proves my point. As soon as the balance tips towards snow and ice: poof! There goes your Oceanic.

Good points but I guess I also wonder at what point of snow cover does a climate switch from oceanic to semi-continental to continental. Is it one week? two weeks? a month? three months? And can a Cfb climate have one winter that is semi-continental and another that is not? For instance, Vancouver's coldest month on record was January 1950 with an average high of -2 (28F) and a low of -9C (16F) which would qualify as full blown continental. Does that mean that Vancouver is not a true oceanic climate like London or Dublin because they have never had a month like that?

Altitude is a difficult variable to incorporate into the matrix.
