It seems a bit early to be talking about the Japanese winter again, but I suppose with many people heading over here to Japan next season, they may be interested!!

Japan is hot and humid during the summer, a fact that sometimes surprise people who only head to a cold(ish) Japan in the winter. In Tokyo, for example, the average August maximums are around 32 degrees, and overnight minimums around 25-26. The humidity is generally between 55% and 85% on clear sunny days.
There is a rainy season in June/July (about 3 weeks) and a typhoon season around September.

The seasons in Japan are distinct and sometimes quite abrupt. So for example, the 32-35 degree days will suddenly stop around 1st/3rd week in September, with 28-30 the norm.
Towards winter, the maximums will generally change from around 12-15 degreesin last Nove/Dec down to 6-10 just before Christmas.


At the moment, it's been a bit above average for August in Tokyo (32.5), but it's been very dry, with only 25mm of rain in the first 22 days of August.(the average is around 180mm) however, the humidity is still around normal for August.

The air in Tokyo (and even away from the cities) is generally hazy in summer, because of the humidity. Winter is the clearest, because the humidity is so low. I'd say that from Yokohama, you can see Mt Fuji(70km away) probably 20 days a month in winter. In summer, it's unusual to see Mt Fuji more than one or two days a month, from May to September.

However, Fuji has been visible for the last three mornings, and not just visible, but crystal clear!!!!! And I've seen Fuji probably 10-12 days so far this August.

What does this mean? I have no idea!!

As we approach the season, I'll give some updates, and if I get time, I'll post some info on winter wind direction and snowfall, based mountain topology.

Re: Japan 2012-2013 the coming snow season

I am in Myoko at the moment working on my lodge. Thankfully, from one of your posts on another thread I was warned that Japan would be hot and humid in August.

Whilst not as hot as Sydney or Brisbane, the humidity is amazing. The concrete walls in my basement are wet, the mirrors have condensation on them, the outside of my car windscreen has condensation when I drive at night etc.

The mountains across the valley are hidden by a haze. Surprisingly the mountains are quite blue, almost like the those in Australia wrt colour.

After battling a jungle in Frenchs Forest for 10 years I am now battling a jungle here. I was thinking that with respect to the insects I would not have as many bitey things, especially ticks. Wrong! Whilst we have flies in Australia we don't have the variety of bitey things that are finding me here. To my surprise, considering how wet it is, I have not encountered any leaches.

I will be coming back for 2 weeks in October abd I am glad to read that it will be much cooler.

Re: Japan 2012-2013 the coming snow season

It's not as hot at Myoko because of elevation...

You must look out for those insects that hang out near grass after dark. they bite below the knee and you get blood blisters that take two weeks to heal.

The haze is evident even outside of the city, which is why three clear, haze free days is unusual in Tokyo.

To late! Though they should be healed enough to wear my ski boots next week.

Semantics Sandy
I was talking about the surf..Ideally for decent waves you want the typhoon to move like this.

The typhoon is not passing anywhere near Miyazaki.

So swell ain't weather...? I'm interested in all sorts of weather...
I reckon a whole lot of other peeps are as well.
Ive always watched how the cyclone season progresses in SE queensland and how that relates to snow here.

It seems as though there exists a strong ridge of high pressure over Japan for the past yonks. With predominantly offshore winds.
Hence why its been so clear in some of the cities.
Japan has had great waves this year i've heard...
It had great waves last year...With an awesome winter following.

Actually Sandy, it is a direct hit with Japan. Just not Honshu or any of the other large islands. But it passes right of the Ryukyu Islands, all of which are Japan.

This is usual for Japan. Off shore SW winds are the normal prevailing winds in summer. That doesn't explain the clear air visibility, as the humidity is just as high as normal, and the temperatures are close to normal.

I am surprised that there is still a stationary boundary off to the NW of Japan this late in August, however.

Regarding the stationary boundary, I'm wondering if it's been a blocker for air movement in the SE / NW direction.... it's been very dry in Tokyo, and perhaps this may explain some of it.

hence the lows have been skirting it lower than usual
longer fetch..better surf season down south.

If it doesn't rain or rain much in Yokohama today, it will be the second driest August on record. There's only been 18mm of rain so far this month.
Same applies to Tokyo with only 25mm. The average seems to be around 160mm.

In spite of the lack of rain, the humidity is no different to usual.
e.g.
This morning 6am:

Tokyo 27.8 degrees (a low of 27.6), 81% Rel humidity
Yokohama 26.5 degrees (a low of 26.3), 88% Rel humidity



This morning 7am:

Tokyo 28.0 degrees, 80% Rel humidity
Yokohama 27.9 degrees, 80% Rel humidity

Sandy, Used to live in Osaki in Shinagawa and in Kyoto. That August weather is horrible, but should end soon :).
As you know, Oct 1 is close and everyone starts wearing their coats and the weather follows.

Indeed!!! I'm looking forward to the step change in the weather, when it drops from 32-34 degrees, down to 27-30, just for starters!!!! It will probably in the next 2-3 weeks.

It's true as they say, that the Japanese tend to dress by season rather than temperature!!!!!

So Tokyo &amp; Yokohama have the 2nd driest August on record.....

And then the first two days of September yield twice as much rain as the entire month of August!!!!

The locals at Myoko have told me that because they have had a dry summer they expect above average snow falls again this winter. Not sure if we actually want this though as it was a bit of a surprise to see the amount of roof damage there was from the snow.

Don't always listen to the locals...... I was told that if there are a lot of stink bugs, you get a lot of snow. Has there been many stink bugs this summer in Myoko ? Not may in Nozawa.

We have had an incredible amount of dragonflies in Darwin this dry season.Does this bode well for Myoko snow?
