A typhoon-turned-extratropical cyclone causes flooding in the east of Japan [Marine summary (June 28, 2026-July 4, 2026)]

2026/07/08 01:09

On June 28, an extratropical cyclone that changed from Typhoon No. 7 moved east-northeast in the east of Japan, accompanied by a front. As a result of this, the waves rose from the east of Japan to the south of Japan, and there was a storm in the east of Japan.
Sea surface temperatures continued to be significantly higher than normal off the southeastern coast of Hokkaido, reaching a maximum of 5 C above normal.

Below is the ocean summary (June 28 - July 4, 2026)



#Pressure distribution and waves
On the 28th, an extratropical cyclone that changed from Typhoon No. 7 moved east-northeast in the east of Japan. A front extending from the low pressure system passed through the south of Japan and extended into southern China. Waves were rising from the east of Japan to the south of Japan, and there was a storm in the east of Japan.
From the 29th to the 30th, the seasonal rain front remained stationary from south of Kyushu to south of Honshu.
On July 1st, a low pressure front formed in the Yellow Sea and moved east-northeast, causing waves to rise in the Yellow Sea.
On the 2nd, the rainy season front stalled near Honshu. A low pressure system moved eastward near Wakasa Bay. Waves increased off the coast of San'in, west of Kyushu, and from Shikoku to Tokai.
On the 3rd and 4th, a low-pressure system accompanied by a front moved away from east of Japan to far east of Japan. In the east of Japan, waves increased around low pressure systems and fronts.



#Sea surface temperature
In the Japanese waters, areas with higher than normal sea surface temperatures have expanded.
The sea area from the East China Sea to the Nansei Islands and south of Japan continued to be at normal levels.
The waters off the southeast coast of the Kanto region continued to be slightly lower than normal, and the waters near Chichijima continued to be slightly higher than normal.
The eastern part of the Kanto region continued to be slightly lower than normal, and the waters off Sanriku continued to be slightly higher than normal.

Today is Tanabata. What's the weather like tonight Let's look for "Orihime Star", "Hiko Star", and "Milky Way"

2026/07/07 11:42

#Let's look for ``Orihime Star'', ``Hiko Star'', and ``Milky Way''
Today, July 7th (Tuesday), just after 9:00 p.m., if you look up at the eastern sky, you will see the ``Summer Triangle.''
The three stars of the ``Summer Triangle'' are extremely bright ``1st magnitude stars'' among all the stars.



Among these three stars, two particularly bright stars are "Orihime Star" and "Hikoboshi".
The bright star that rises first and can be seen from a high place and is to the north is "Orihime Star".
Orihime star is called Vega in the constellation Lyra in the West, and Hikoboshi is called Altair in the constellation Aquila.
In addition to Orihime Star and Hiko Star, another bright star is Deneb in the Cygnus constellation.
Also, where the air is clear and there are no city lights, you can enjoy the Milky Way.
The Milky Way flows from Deneb through the Summer Triangle and between Vega and Altair.

#What's the weather on Tanabata night
Today, July 7th (Tuesday) at 9pm, Okinawa will be covered by a Pacific anticyclone, and the night will be clear, so Orihime, Hikoboshi, and the Milky Way will be visible in many places.
The seasonal rain front is expected to slowly move south over the southern coast of Honshu, but western Japan will be covered in clouds due to the moist air, and there will be some showers.
On the East China Sea side of Kyushu, there seems to be a chance to peek at the starry sky of Tanabata through the gaps in the clouds.



Parts of the Tokai region will also be sunny, so you can enjoy the starry sky of Tanabata, but there will be showers along the mountains.
There are a lot of clouds in the Kanto region, and the sky is likely to be unlucky for observation.
The Sea of Japan side of Hokuriku and Tohoku, and near the Oshima Peninsula in Hokkaido, there are places where you can see Orihime Star, Hikoboshi, and the Milky Way.

#The 25th is a new moon; the influence of moonlight is small, making it easier to see the Milky Way.
The Stars of Tanabata can be seen past July 7th and into August.
This year, there will be a new moon on July 25th (Saturday), so the influence of moonlight will be less during the new moon, making it easier to see the Milky Way.

Today's weather on the 7th (Tuesday): Widespread cloud-dominated sky; heat stroke warning mainly in western Japan

2026/07/07 06:26

On Tanabata, the 7th (Tuesday), the rainy season front is expected to move south of Honshu, and the front's activity will weaken. However, the weather will not recover clearly, and clouds will likely spread throughout the day.



In Hokkaido, there are times when the sun reaches southern Hokkaido, but the sky looks like clouds tend to spread. There is a possibility of rain showers, so it's a good idea to bring a foldable umbrella with you when you go out.
It will be sunny in many places on the Sea of Japan side of Tohoku and Hokuriku. On the other hand, there are many clouds on the Pacific side of Tohoku, and there is a possibility of showers here as well.

Clouds are expected to spread throughout the day in the Kanto region. Although it is not extremely hot during the day, it can feel a bit humid. It is a good idea to choose clothes that are breathable.

There will be periods of sunshine during the day from the Tokai region to western Japan, but the day will be dominated by clouds. Be careful of sudden changes in weather especially along the mountains. The temperature in many places exceeds 30 degrees Celsius, so you'll feel hot and humid. Please take measures to prevent heatstroke, such as drinking plenty of water.

The summer sky seems to be widening in Okinawa. Please continue to be careful of heat stroke.
