Japan Meteorological Agency Announcements

• Entering the rainy season in the Kanto Koshin region.
• 8 days earlier than last year and 1 day earlier than normal.

• There is an average “change” period of about 5 days in the rainy season.
• The due date may be revised as a result of consideration of the actual weather conditions from spring to summer.

Future Weather Forecast

Although the Baiu front will move to the south after tomorrow 7th (Tuesday), it is expected that cloudy and rainy days will continue. It is highly possible that the next Baiu front will move north after next weekend.

Regarding the end of the rainy season, in the Kanto Koshin region, it is mid-July in normal years, but there is a possibility that the end of the rainy season will be earlier this year due to the influence of La Niña.

Even if the rainy season is short, it may be a torrential rain, so you cannot be alert. Especially from the latter half of June to the beginning of July, frontal activities are expected to become active, so please take measures against the heavy rain season as soon as possible.

Expectation of Rains In Various Places

In the area from Kyushu to Tokai, it is expected that the rainy season will be delayed from the normal year. As the fronts move south this week, it is possible that the rainy season in each area will start after the next weekend at the earliest.

However, during this period when it is easily affected by moist air, the atmospheric conditions may become unstable, so please check the daily weather forecast.
