[One-Month Forecast] Temperatures are expected to be higher than average across eastern and western Japan as the region remains prone to being covered by warm air; conditions are also likely to be influenced by low-pressure systems and fronts.

2026/11/12 17:54

The Japan Meteorological Agency (JMA) released its one-month forecast today, Thursday the 12th, covering the period from November 14 to December 13.

Over the next month, the entire country is likely to be covered by warm air, with temperatures expected to be higher than average, particularly across eastern and western Japan.
Additionally, as the country will be prone to the influence of low-pressure systems and fronts-especially during the early part of this period-precipitation is expected to be above average along the Pacific coast of northern Japan and the Sea of Japan coast of eastern Japan. Along the Sea of Japan coasts of northern and western Japan, precipitation will likely be near or above average.



Regarding the one-month average sea-level pressure (left chart), higher-than-normal pressure is expected south of Okinawa, while a trough (an area of ??low pressure) is forecast to extend from the Sea of Japan toward Hokkaido. The entire country is likely to be affected by low-pressure systems and fronts, particularly during the beginning of the period.

Temperatures at an altitude of approximately 1,500 meters (right chart) are expected to be higher than average, especially over eastern Japan, as the region is likely to be covered by warm air. Conversely, a slight negative deviation is indicated for the Sea of Okhotsk, while in western Japan, Okinawa, and the Amami region, temperatures will remain close to the seasonal average, with the possibility of occasional influence from cold air.



alt=""Image"" width=""500"" height=""281"" /> This forecast covers the expected average temperatures, precipitation, and sunshine duration for the next month, along with weekly average temperature projections (including the probability of occurrence in %).

As the country is likely to be covered by warm air, temperatures over the next month are expected to be above average in Eastern and Western Japan, and near or above average in Northern Japan, Okinawa, and the Amami region.

Due to the anticipated influence of low-pressure systems and fronts-particularly early in the period-precipitation over the next month is expected to be above average along the Pacific coast of Northern Japan and the Sea of Japan side of Eastern Japan. Across the Sea of Japan side of Northern to Western Japan, precipitation is likely to be near or above average. On the Sea of Japan side of Eastern Japan, more cloudy or rainy days than usual are expected.

Sunshine duration over the next month is expected to be below average along the Pacific coast of Northern Japan, and near or below average along the Pacific coast of Eastern to Western Japan. Fewer sunny days than usual are anticipated along the Pacific coast of Northern and Eastern Japan. In Western Japan (Pacific side), while the weather will shift in a cycle every few days, there will likely be fewer sunny days compared to a typical year.

This past week, many areas-especially in Northern Japan-experienced temperatures below average due to the influence of a strong cold air mass. Looking ahead, however, there will be days where temperatures rise above average, particularly across Eastern and Western Japan. That said, cold air may still occasionally push southward, causing temperatures to drop; please adjust your clothing accordingly to stay healthy amidst these temperature fluctuations.

Furthermore, the region is expected to be susceptible to the influence of low-pressure systems and fronts, especially early in the period. Around the 18th-19th, a low-pressure system is forecast to develop rapidly as it moves across the Sea of Japan, which may lead to stronger rain and wind. In Northern Japan, snowfall could also reduce visibility in some areas. Please check the latest weather forecast daily.

Weather forecast for the Chugoku region: Sunshine is expected until tomorrow, the 13th, but the weather will deteriorate from the 14th onwards.

2026/11/12 16:40

"Here is the weather forecast for the Chugoku region.
Today, the area around Japan is under the influence of a high-pressure system.



The Chugoku region has been mostly clear, with plenty of sunshine. There is no risk of rain tonight.



Tomorrow, while some areas may see clouds in the morning, the day is expected to be generally clear. High temperatures will exceed 20C in many places-warmer than the seasonal average.



Looking ahead, a front will approach from the west on Saturday the 14th, leading to a deterioration in the weather. Rain may begin in some areas by the afternoon, and widespread rain is expected on Sunday the 15th.

" />

On Monday the 16th, a winter-type pressure pattern will develop, bringing rain to areas along the Sea of Japan coast.
From Tuesday the 17th through Wednesday the 18th, a low-pressure system accompanied by a front is expected to move across the Sea of Japan while intensifying rapidly, leading to widespread rain once again. Winds will also strengthen, likely resulting in driving, slanted rain. As the front passes, there is a possibility of heavy rain or thunderstorms, so please be sure to check for the latest updates.
On Thursday the 19th, a winter-type pressure pattern will return, bringing rain to the Sea of Japan side of the region. Temperatures are expected to drop significantly, so you will likely need a warm outer layer.
That concludes the weather forecast for the Chugoku region.

Weather for this weekend: Conditions to deteriorate from the west, with rain expected across a wide area on Sunday.

2026/11/12 14:06

This coming weekend, from Saturday the 14th to Sunday the 15th, a weather front and a low-pressure system will approach from the west, causing conditions to deteriorate, starting in Western Japan. If you are planning any outings, Saturday is the better choice.



Today, Thursday the 12th, much of Japan is under the influence of a high-pressure system, resulting in clear skies across many areas. Tomorrow, Friday the 13th, while clouds may develop in some places, the high-pressure system will persist, keeping skies mostly clear.
Looking ahead to the weekend, a weather front and a low-pressure system are expected to approach, leading to a decline in weather conditions, beginning in Western Japan.

On Saturday the 14th, a low-pressure system is expected to form along a front and move eastward. By the afternoon, rain will likely begin to fall in Kyushu, Okinawa, and the Chugoku region.
On Sunday the 15th, the low-pressure system is forecast to travel across the Sea of Japan and pass near Northern Japan. A cold front extending from this system will sweep across much of Honshu, bringing rain to a wide area stretching from the Tohoku region down to Okinawa. Hokkaido is also expected to see an increase in cloud cover.


As a weather front and an area of low pressure pass through, rainfall may intensify in some places. Winds are also likely to pick up, especially along the coast, so you will probably need a sturdy umbrella.
Additionally, warm, moist air will flow toward the front and the low-pressure system, making atmospheric conditions unstable-particularly across the Okinawa and Kyushu regions. Please be on the lookout for lightning, sudden gusts of wind, and intense, short-lived downpours.





Daily high temperatures are expected to be around or above the seasonal average. Even though clouds may spread across the sky, warm air brought in by southerly winds will keep temperatures on the higher side.
Expect highs of around 10C in Hokkaido, over 15C in many parts of the Tohoku region, and around 20C across the Hokuriku, Kanto, and western Japan regions.
Be sure to adjust your clothing appropriately to avoid falling ill due to temperature fluctuations.

From Calm Sunshine to a Dramatic Change: Weekend Rain and Stronger Rain and Winds Expected by Midweek Next Week (Weather Commentary by Meteorologist Junko Miyake)

eather conditions will remain sunny through Friday, but rain is expected to spread from the west over the weekend.

First, let's take a look at the current weather distribution.

As of 11:00 a.m. today, many areas across western and eastern Japan, as well as the Pacific side of northern Japan, are enjoying clear skies.

Some rain is falling along the Sea of Japan side of northern Japan, but it is generally light, with rainfall amounts of around 1 to 2 millimeters per hour.

High pressure will continue to cover the region through tonight, bringing mostly sunny weather to much of Honshu.

This high-pressure system extends across the continent, forming an elongated ridge of high pressure.

Sunny conditions are expected to continue across much of Japan through Friday.

However, weather conditions will begin to deteriorate from the west starting Saturday.

A front and low-pressure system will approach from the continent, and rain is expected to gradually begin across Kyushu during Saturday afternoon.

The system will then strengthen somewhat as it moves across Japan with its associated front.

As a result, widespread rain is expected on Sunday, November 15.

Around Tuesday, November 17, a similar pressure pattern to that of Saturday, November 14, is expected to develop, with another front and low-pressure system approaching from the west.

However, the low-pressure system expected next week is forecast to intensify rapidly near Honshu.

Compared to the system affecting Japan this weekend, next week's low is expected to be stronger and may bring heavier rain and stronger winds nationwide.

Please pay close attention to forecasts for rain and wind next week.

Detailed forecasts for each region follow.

For the rest of today, Thursday, sunny weather will continue in many areas.

Temperatures will rise to around 20C during the day, bringing mild and pleasant autumn conditions.

On Friday, although there will be some clouds, generally sunny weather is expected to continue.

Temperatures will rise even higher than today, and from the Kanto region westward, it may be comfortable enough to spend the daytime outdoors wearing just a long-sleeved shirt.

Now for the weekly outlook.

On Saturday, November 14, rain will gradually begin across Kyushu.

As the day progresses, the area of rain will steadily expand eastward.

By Sunday, November 15, widespread rain is expected from Kyushu to the Tohoku region.

Warm southerly winds will accompany the system, meaning that even in Tohoku, precipitation is expected to fall mainly as rain rather than snow.

On Monday, November 16, colder air will move in, and snow is expected in Sapporo.

Wednesday, November 18, a developing low-pressure system may bring stronger rain and winds across the country.

Please continue to monitor the latest weather information.
