Japan Meteorological Agency 1-Month Forecast Temperatures will be above normal, but the season will continue

The Japanese islands are easily covered by warm air, and temperatures tend to be high throughout the country. The average temperature for the month is expected to be above normal, with an 80% chance of it being higher from Tohoku to Kanto-Koshin and Okinawa.

In particular, early weather information regarding high temperatures has been announced for Tohoku, Kyushu, and Okinawa, as the average temperature for the five days starting around October 30 (Wednesday) is likely to be significantly higher than the usual

The temperature is high throughout the month, but there are times when the temperature drops, especially in northern Japan, due to temporary cold air moving south. Temperature changes can be large.

In addition, although the temperature is higher than normal, in November the normal temperature itself drops significantly in different places. The normal maximum temperature in central Tokyo is 16.6 ℃ in mid-November, while in Osaka it is 17.6 ℃, below 20 ℃. The season is progressing, although it is slower than usual.

▼ Seasonal maximum temperature in November (standard value)
Early Late Middle
Sendai 16.3 ℃ 13.9 ℃ 12.0 ℃
Tokyo 18.6 ℃ 16.6 ℃ 14.9 ℃
Osaka 20.0 ℃ 17.6 ℃ 15.9 ℃

In southeastern Japan, the Pacific high pressure system to the east is still sluggish, and there are many days when the area around western and eastern Japan becomes a “pressure pool” with relatively low weight.

Autumn water fronts usually become dead, and if the front becomes more active due to the influence of moist air, there is a risk that the rain will become heavier.

In Tohoku, eastern Japan, Kinki, and Chugoku-Shikoku, monthly precipitation is expected to be at or above normal.

Also, in October, as in September, it is possible that a typhoon will form in the southern seas of Japan and affect Japan. In addition to the autumn water front, it is also necessary to take into account the movements of typhoons.

High pressure will dominate from mainland China to the Sea of ​​Okhotsk, while areas around Honshu will be more susceptible to low pressure and frontal effects.

Western Japan, the Tokai region, and the Kanto region are expected to have fewer sunny days and more precipitation compared to normal years. Since Hokkaido is covered with high pressure, precipitation on the Sea of ​​Japan side will be at or below normal.

Even in October, typhoons are still appearing over the sea south of Japan, and it is likely that frontal activity will increase. It is possible that the rain will get heavier even in November, so don’t let your guard down.
