The farthest-inland oceanic climate I have found so far is Frankfurt (https://en.wikipedia.org/wiki/Frankfurt), approximately 350km from the nearest point of coastline (near Bergen op Zoom in the Netherlands) but I was wondering if anyone here knew of any others farther from bodies of water.

Budapest?

Basically any climate in Bavaria, southern Czech Republic and central Hungary should fall within oceanic under Köppen. A nasty one is the one in Skara, Sweden; more than 100 km from the Atlantic Ocean, aided by a large interior lake. Skara is north of 58 degrees latitude. In south Småland there are several similar oceanic climates in Sweden such as Ljungby and Växjö at around 56-57 degrees latitude, which is kinda impressive that they are not continental at such a latitude and inland.

Depends on if you go by Koppen's dumb -3C threshold.

For places like Skara, it would be best to wait for SMHI's official 1981-2010 data. Since they are crap, they won't release that data until the rest of the world releases 1991-2020 data.

Skara is oceanic by 2002-2015 in the monthly reports SMHI release (http://www.smhi.se/klimatdata/meteorologi/2.1240). Unfortunately the SMHI's data delivery for long-range averages is pretty dull.

Having said that, their next release is in fact 1991-2020. The 1961-1990 numbers for Northern Europe are hopelessly inaccurate due to a severe cold spell that it in fact was.

Personally I rate -2 C as a good isotherm for oceanic, because snow cover usually thaws fairly quickly in such a climate. The small town that I live in is just around it. Winters are so evenly distributed (south of the Greater Stockholm region but within range).

Since I moved here in 2002, around 50 % of winters have had a 'proper' winter month. Only 2006 and 2010 saw significant snow cover in March.

Last winter saw the first three weeks of January resembling a cold wave with average highs of -4 and lows of -12. Very continental. But then the last week saw averages similar to your hometown over in England (!) so it ended up avg high -2 and low -8 for the coldest January since the https://en.wikipedia.org/wiki/2010_Swedish_cold_waves (author pats himself onto head)

Most other winters follow a strange pattern. Severe seasonal lag keeping Christmas green. New years' night has been above freezing six years in a row and this is not anywhere near Sweden's southern tip nor super-maritime. In fact, even inland areas like Örebro has experienced this.

Then for two weeks in January highs fall below freezing but cloudy nights keep lows in check. Most of the time a minor snow cover builds up, but is melted away as soon as the warmer maritime air from England breaks through early February. What then follows is the most dull oceanic month. Clear weather is frequent often bringing the nights below -7, but days below freezing are few and far between, with only the occasional Arctic blast moderating averages. The general feeling of February is + 2 day -4 night on a normal occasion.

So, the climate is clearly heavily modified by the Gulf Stream, but also cooled and warmed somewhat over land in winter and summer. The adjacent Baltic Sea also helps moderating the lows in what otherwise would be a stonewall continental climate.

So it is not easy to define southern Sweden. Örebro is around -3 in recent decades, but the general feeling about that place is continental. Here nearer the coast though... semi-continental climate slightly leaning oceanic.

I hope this account from a resident cleared things up a bit!

Well even the 2002-2015 averages would be record breaking cold here.

Yeah, I think so. I'll try and compare the December 2010 values for UK with January averages for 'maritime Sweden'.

Bradford: 2.3/-3.7
Sheffield 2.7/-1.9
Durham 2.7/-3.4
Shawbury 2.0/-5.8
London 3.9/-1.5
Cardiff 3.9/-3.4
Glasgow 1.6/-4.4
Oxford 2.7/-2.2
Braemar 0.8/-8.1
Wick 3.5/-2.9
Lerwick 3.7/-1.2

Only place with a 2010 humid continental year was Braemar.

In Sweden it's more like this in a normal January around the northerly fringes of the below snowline areas:

Norrköping 0.8/-4.3
Skara 0.6/-4.1
Örebro 0.3/-5.6
Växjö 0.4/-3.7
Ljungby 0.7/-4.0
Kalmar 2.0/-3.4

So in other words, by no means a safe winter except maybe in Örebro - and there are times there is no need to use gloves on January 15!

Having said that in December 2010 (http://data.smhi.se/met/climate/time...ec10.pdf?66120) Sweden looked like this.

Norrköping -4.8/-11.7
Skara -5.0/-12.0
Örebro -5.6/-13.7
Växjö -4.7/-10.4
Ljungby -4.8/-13.4
Kalmar -3.2/-11.4

But it's also well worth a look at this the extreme lows of January 2008 (http://data.smhi.se/met/climate/time...an08.pdf?66120)

Norrköping -6.6
Skara -6.1
Örebro -8.8
Växjö -5.5
Ljungby -6.4
Kalmar -4.8

That's also pretty whooping for a 'continental area' that it's even possible. So there is why I'd consider the entire south of Sweden a maritime transitional climate!

Would still consider nearly all of them continental, just wish maritime influences. Coming from an actual maritime winter, it would feel very, very cold. In December 2010, we had snow most of the month despite averages higher than an average January in Sweden, so I presume an average January in southern Sweden would be cold enough for the snow to stock around most of the time.

Where is your line for maritime? 0, -1 or -2?

Some deep-south climates of Sweden go above 0 even during the 1961-1990 obsolete averages.

(Falsterbo, Malmö and Helsingborg). In effect they're interior locations due to the small straits that separate Sweden and the Danish isles from Denmark's mainland (Jutland).

Well, they'd be true transitional climates.

I consider even the 0c line ridiculous for oceanic climates. An oceanic climate should not have freezing winter lows, let alone means!
