Record-breaking heat continues in western Japan; heavy rains in Tohoku and Hokuriku at the end of the rainy season (weather summary July 26, 2026 - August 1, 2026)

2026/08/06 18:44

This is a summary of the weather for this period (July 26th to August 1st, 2026).

#Summary of the weather for this period (July 26th to August 1st)
The average temperature was the hottest on record, mainly in western Japan, which was covered by an anticyclone, and some locations recorded extremely hot days. In northern Japan and Hokuriku, where there were many cloudy and rainy days due to the seasonal rain front, temperatures tended to be below normal.

Precipitation exceeded normal levels mainly in Tohoku and Hokuriku, which were susceptible to the effects of the seasonal rain front, and some places in Hokuriku experienced heavy rains during the period, breaking the highest in recorded history. On the other hand, western Japan was covered in high pressure for many days throughout the period, so there were many places where the total precipitation during the period was 0 mm.

Sunshine hours tended to exceed normal levels, with many sunny days in western Japan, which is covered by an anticyclone. Northern Japan and Hokuriku, which were susceptible to the effects of the rainy season front and humid air, tended to have many cloudy and rainy days, with temperatures well below normal.



[About the weather during this period]
#Characteristics of pressure distribution
On the 26th, the seasonal rain front stalled from the Sea of Japan to Hokuriku and Tohoku. A low pressure system formed just north of the front. On the 27th, the center of the high pressure system was almost stationary near the Chishima Islands. A front is stationary from the eastern seaboard of Japan to the area off the coast of Tokaido, and a low-pressure system above the front moves eastward east of Kanto. Typhoon No. 13 occurred near the Midway Islands. On the 28th, the center of high pressure became stationary east of the Kuril Islands. The front and the low pressure system gradually left the vicinity of Japan. A low-pressure system moved eastward across the Sea of Japan and became obscured on the 29th. A low-pressure front moved over the sea east of Japan, and a low-pressure system near Primorye approached northern Japan. On the 30th, the low pressure system near northern Japan continued to move south, and the low pressure system above the front left the area near Japan. On the 31st, a front became clear from the center of the low-pressure system moving over the continent, and the front approached the Tohoku region.On the 1st, a new low-pressure system formed near the Sea of Japan on the front and moved toward the Tohoku region. Typhoon No. 13 was very strong and moved westward near Minamitorishima. During this period, western Japan was widely covered by the Pacific anticyclone.

#Precipitation
On the 26th, rain clouds developed around Tohoku, Hokuriku, and Kanto due to the influence of moist air flowing near the front. Heavy rain of 90.5mm per hour was observed in Nanto Takamiya, Nanto City, Toyama Prefecture. On the 27th, rain clouds developed due to rising temperatures and humid air during the day, and heavy rain was observed in Haruno, Hamamatsu City, Shizuoka Prefecture, Unazuki, Kurobe City, Toyama Prefecture, and other areas. On the 28th, rain fell in Tohoku, Hokuriku, and other areas due to the effects of low atmospheric pressure in the upper atmosphere, cold air, and humid air, and extremely heavy rain of 63.0 mm per hour was observed in Tonami City, Toyama Prefecture. On the 29th, rain clouds developed over the Izu Islands near the front, and heavy rain was observed on Hachijo Island. Rain clouds have developed in inland areas of western and eastern Japan, with heavy rain occurring in Aoya, Tottori City, Tottori Prefecture. On the 30th, it rained mainly in northern Japan and Hokuriku, where there was a trough in atmospheric pressure, and extremely heavy rain of 53.5 mm per hour occurred in Obanazawa, Yamagata Prefecture. On the 31st, due to the influence of a front extending from the continent, heavy rain was observed in Muramatsu, Gosen City, and Miyayokami, Kamo City, Niigata Prefecture. On the 1st, the front continued to stay near Tohoku, bringing rain mainly to Tohoku and Hokuriku. In Tohoku, extremely heavy rain of over 50mm per hour was observed in places such as Kanayama-cho and Mamurogawa-cho in Yamagata Prefecture.

#Temperature
During the period, the center of the high pressure system was mostly located in the East China Sea, resulting in record-breaking heat mainly in western Japan. On the 26th, although there were no particularly hot spots, it was extremely hot at 39.4c in Nakamura, Shimanto City, Kochi Prefecture. On the 27th, the temperature reached 40.0c in Hita City, Oita Prefecture, which was an extremely hot day, 39.8c in Kurume City, Fukuoka Prefecture, and 39.1c in Akiota Town, Hiroshima Prefecture. On the 28th, Saga, Kuroshio Town, Kochi Prefecture, recorded a record high of 40.7 degrees Celsius, making it an extremely hot day. On the 29th, strong sunlight hit western and eastern Japan, making it extremely hot. It was an extremely hot day in Miyazaki, with the temperature rising to 38.8c. On the 30th, the severe heat continued from the Kanto region to the west. Temperatures along the Sea of Japan coast from Hokkaido to Niigata fell below normal due to the rain. On the 31st, it became dangerously hot mainly on the Pacific side, with a temperature of 39.6 C observed in Kamikitayama Village, Nara Prefecture, setting the highest temperature ever recorded. On the 1st, western and eastern Japan were still experiencing severe heat, with a temperature of 39.7 degrees Celsius recorded in Tenryu, Hamamatsu City, Shizuoka Prefecture. In Tokyo, the temperature rose to 36.5 degrees Celsius, making it the fourth consecutive day of extreme heat.

1-month forecast Western Japan continues to experience intense heat; Tohoku and Kanto regions experience calmer summer heat during the Obon holiday

2026/08/06 17:42

On the 6th (Thursday), the Japan Meteorological Agency announced the latest one-month forecast, which shows the weather outlook for the next month.



The average sea level pressure for the next month is expected to be lower than normal from the East China Sea to the south of Japan, and high pressure areas are expected from north China to the seas near the Kuril Islands.
For this reason, it is expected that there will be periods when the Sea of Japan side is likely to be covered by high pressure. Okinawa/Amami will be affected by typhoons at the beginning of the period.
Temperatures around 1,500 meters above the ground are higher than normal, especially in northern Japan, and the whole country is expected to be covered in warm air.



The average temperature over the next month is expected to be lower than normal, mainly in eastern Japan, from around the 8th to the 14th. In the Pacific Ocean side of the southern Tohoku region and the Kanto region, the intense heat will subside somewhat during the Obon holiday.



However, temperatures will tend to be higher than normal from the middle of August to the end of August. On the 6th (Thursday), the Japan Meteorological Agency announced an ``early weather advisory'' stating that the average temperature for five days starting around the 14th will be higher than normal in areas from Hokuriku to northern Kyushu.
Western Japan will experience higher than normal temperatures during this period, and the severe heat is likely to continue. In some places, the temperature could reach dangerously high, approaching 40 degrees Celsius. To avoid getting heatstroke, please continue to take precautions to prevent heatstroke on a daily basis.

From now on, areas on the Pacific coast are likely to be affected by humid air, and precipitation is expected to be at normal levels. On the Sea of Japan side, northern Japan, Hokuriku, and western Japan are likely to be covered by high-pressure systems, and precipitation will be at or below normal.

Heavy rain is expected in Okinawa/Amami due to Typhoon No. 13. As the typhoon moves slowly, the effects may last for a long time, so please be extremely cautious of landslides caused by heavy rain, flooding of low-lying areas, and rising and flooding rivers.
After that, even after Typhoon No. 13 leaves, the area is expected to be susceptible to the effects of humid air, so precipitation is expected to be higher than normal.
