Post Oh Nuts! Here comes winter
The inevitable is upon us - colder mornings. Here in northern Kyushu the local temperature depends mostly on location relative to the sea/ocean and also the mountains. The interior gets the lowest recordings of course, while the coastlines, islands, and urban heat islands remain the warmest. In this map FUK is Fukuoka, a large city of 1.3 million folk coming in at 8 C, SASA is Sasaguri, the town I live in of 30,000 that is at the base of the local mountains coming in at 5.2 C, and KIK is Kikuchi City, a small city near Kikuchi Gorge coming in at 2.7 C. Not shown are areas of high elevation which are considerably colder. In my own area where some of the peaks can get up to 1000 meters, they definitely saw frost this morning. I'm also sure that Kikuchi Gorge was near or below freezing this morning. It's all down hill from here I'm afraid. The next warm temperatures we'll see won't come 'til late February at earliest.

Bad as that sounds, here's what I (& my plants) had to contend with this morning!
Two inches of heavy wet snow!

Cheers, Barrie.

Barrie, thank god I won't have to deal with anything like that for another month or so! Honestly, days remain very nice here, just the mornings are cool, and the rains have yet to kick in. Once they do, things get gloomy around here until February.

Brrrr!

No sign of winter here yet. In fact November has been warmer than average, especially at night. November should average 19 by day and 12 by night, but so far we've averaged 21 by day and 16.5 at night. Today reached 24/25 in many areas (more on my balcony, but that definitely doesn't count as an official recording as it's very sheltered and has an aluminium awning over it).

We're supposed to have two fronts passing through next week which will bring a temporary halt to the glorious autumn sunshine. Temperatures aren't forecast to fall too much though...maybe 18-20C days. A southerly wind and cloud-cover tomorrow night might keep the minimum temperature at or above 18C.

I'm not really expecting winter until January/February. I'm hoping for another frost-free season, with a handful of nights below 5C being the worst. But frost down to -6C isn't impossible: we're uncomfortably close to central and eastern Europe.

Currently 17.7C at 9pm. I don't think I need worry about frost tonight.

Barrie, after less than a year here I've already forgotten what cold is! If you fancy moving to Greece I'll give you free Greek lessons and lots of plants and cuttings!

Four years until retirement. Sounds inviting although it's much too far from home and family. I doubt my wife would be on board with the idea.
I suspect a few winter months in Arizona would be much closer and no language barrier. There's 10's of thousands of snow birds there each winter so we'd have plenty of company.

Cheers, Barrie.

I'm less than a 4 hour flight from the UK, so friends and family have no problem getting here and - not surprisingly - seem quite keen to come!

I'll bet! :D Here, a 2½ hr flight and you're in the sunniest place on earth, Yuma Arizona.

Cheers, Barrie.

Coldest morning yet, down to 3.1 C in my area. Crystalline frost on the open fields and cars. Boo Hoo!

Athens remains unusually mild for the time of year, with an overnight low of 19.9C (68F). You know something's seriously wrong with the weather when you open the patio windows on a late November morning to let the warm air in.

They're linking this weather with the same shift in the jet stream which is bringing the snow to other parts of Europe.

Dave ... what would the average be if 19°C is higher than normal? If it's 15°C you'd still be in fine shape really.

Our brief visit from old man winter is over for now. Calm and sunny (snow melted) and 10°C. Now, it's back out into the garden!

Cheers, Barrie.

The average November night is 12C (54F), and the average December night is 8C, so I guess 10C (50F) would be normal now. Last night was almost 10C above that.

In fact we've only had one night this month which dropped to 12C, and the average low so far this month is over 16C (61F). It'll be quite a shock to the system when winter finally arrives here!

According to one on-line source, based purely on correlations between past weather events, Greece usually gets a cold snap about 40 days after the UK gets affected by a 'blocking high' in winter. That would mean we're due for a cold spell in mid January....which is when we'd expect some cold weather anyway.

Dave and Barrie, both your situations show the ups-downsy nature of short term cycles. Definitely odd stuff, but I'm sure not unprecedented historically. Boy, what I wouldn't do for a 18 degree night now though...

Here we mostly have been seeing odd weather in terms of wet or dry periods, many of which have been out of sync with norms, and also above normal temperature cycles, especially in summer and late winter. Things have definitely changed a lot in the past 20 years. The trend is surely warmer highs, year round, a loss of snow fall and pack, and disturbances in the summer monsoon cycle some years. Looking at the climate data for just about anywhere in Japan (urban centers or in the Japanese Alps) there is an unmistakable heating trend since the onset of WWII or there abouts.

Dave ... I guess all you can say is, enjoy the weather while you can, which is what most of us do anyway in our own climates. Hope the 40 day cycle isn't nasty by Greek standards if it does develop.

Tom ... sounds like your area is experincing noticable changes beyond what would be considerd reasonable / normal? Our region seems to have changes but to a lesser extent (so far). The older I get the less tollerable I am to change :lol:
Hey ... an 18°C night would be fine but I'd be thinking of what repercussions of such an event.

Cheers, Barrie.

Barrie, I'm not sure if it is typical or not. Here's the graphed data for the years 1890 to 2006 showing average annual temperature for Fukuoka City. There has been a pretty steady increase overall since 1940-45. This same pattern holds for Kyushu and no doubt much of Japan.

Weather's always going to be above or below average more often than it is exactly average! The UK is very prone to 'cold snaps' because the Gulf Stream normally keeps it so much milder than you'd expect for that latitude. If a 'blocking high' develops in winter (as it often does) then the Atlantic depressions can't bring the mild air, and the UK gets a taste of what being at 55 degrees North really should feel like.

Greece is quite prone to shifts in weather too, especially in winter. 'Normal' conditions are affected mostly by the relatively mild Mediterranean sea around us. But Africa is just south of us, and we often benefit from warm southerlies; just as often, however, we can be affected by cold northerlies from our neighbours in Bulgaria and the former Yugoslavia.

You mean in terms of plants not going dormant before cold weather strikes? Yes, it must have an effect some years. Some plants go dormant simply because of natural cycles, or shorter days, or lower light levels (or a combination), but there are still lots of others in active (but slow) growth: hibiscus rosa-sinensis, epiphyllums, colocasia, alocasia to name but a few. Everything's in pots though, so I can bring things indoors if necessary.
