The Okinawa Meteorological Observatory announced today, June 25 (Sunday), that the rainy season is believed to have ended in the Okinawa region. Summer is coming four days later than normal and five days later than last year.
This year, the rainy season ended earlier in Okinawa than anywhere else in Japan.
At the end of the rainy season, which is slightly later than usual
The overhang of the Pacific anticyclone has strengthened, and there are many sunny places in the Okinawa region. The Okinawa Meteorological Observatory announced the end of the rainy season because it is expected that there will continue to be many sunny days over the next week as the Pacific anticyclone continues to cover the area.

The end of the rainy season in Okinawa
4 days later than normal, 5 days later than last year
・After the rainy season, there is a period of “transition” of about 5 days on average.
・As a result of consideration of the actual weather progress from spring to summer, the date may be revised.
In normal years, the rainy season ends around June 21st, so the rainy season ends a little later. June 23rd, “Memorial Day” has the impression that it will be blazing hot, but this year it is a little later than that. However, the Sakishima Islands have been covered by the Pacific high-pressure system for about a week, and the main island of Okinawa and the Daito Island region have been sunny since yesterday, so many people may have the impression that midsummer has already begun. I can’t.
In terms of duration, this year’s rainy season began on May 18, making it a little shorter than the average year of about one month and one week (preliminary figures). This year, due to the effects of Typhoon No. 2 and the subsequent stagnation of the seasonal rain front, it rained more than usual in Naha and the main island of Okinawa. On the other hand, the Sakishima Islands and the Daito Island region experienced less rainfall than normal.

Future weather forecast
According to the weather news forecast, it is expected that the midsummer sunshine will continue to reach various parts of Okinawa. There is a possibility of sudden showers like in summer, but unlike the rainy season, most of the rain will be short-lived.
Midsummer days with maximum temperatures of 30°C or higher are expected to continue in various places, and hot nights with temperatures of 25°C or higher are expected to continue in the mornings and evenings. Be careful of heat stroke and strong UV rays.
When will the rainy season end nationwide?
The Amami region of Kagoshima Prefecture is also expected to continue to be covered by the Pacific anticyclone, so it is expected that the meteorological observatory will announce the end of the rainy season in the near future.
From Kyushu to Tohoku, the rainy season is in full swing. According to Weathernews’ forecast for this year’s rainy season, the rainy season is expected to end around mid-July in Kyushu and Kanto-Koshin, and around the end of July in Hokuriku and Tohoku.
In the first half of July, the seasonal rain front will be active and rainfall will increase, so please be prepared for heavy rain. In the second half of July, the Pacific High is expected to expand northward, and the stagnant position of the Baiu front will move northward and become unclear.
Preliminary figures for the start and end of the rainy season may be revised in the fall
The rainy season is a time when disasters are likely to occur due to heavy rain and is of great public concern. I am making an announcement.
Since this is just a preliminary report using forecasts, final values used in statistics such as normal values may be updated in the fall, taking into account actual weather conditions.
Last year, the dates for the start and end of the rainy season were significantly revised in the fall, and in some areas, there was a major revision of more than 20 days.

How has the Pacific anticyclone contributed to the sunny weather in the Okinawa region?
The Okinawa Meteorological Observatory announced today that the rainy season has ended in the Okinawa region. This year, the rainy season ended earlier in Okinawa compared to other parts of Japan.
The Pacific anticyclone has strengthened, resulting in many sunny days in the Okinawa region. The observatory predicts that there will continue to be sunny weather over the next week due to the coverage of the Pacific anticyclone.
In terms of timing, the end of the rainy season is slightly later than usual. Typically, the rainy season ends around June 21st, but this year it ended a little later. While June 23rd, known as “Memorial Day,” is usually very hot, this year’s temperatures were delayed. However, the Sakishima Islands have been experiencing sunny weather for about a week, giving the impression that midsummer has already arrived.
The duration of this year’s rainy season was slightly shorter than the average, starting on May 18. This was due to the impact of Typhoon No. 2 and the subsequent stagnation of the seasonal rain front. Naha and the main island of Okinawa received more rainfall than usual, while the Sakishima Islands and the Daito Island region experienced less rainfall.
The weather forecast for Okinawa predicts that the midsummer sunshine will continue, with the possibility of
It seems like nature has decided to take its time bidding farewell to the rainy season in Okinawa this year. Mother Nature’s unpredictable ways remind us to embrace the unexpected and cherish every change of season.
It’s fascinating to see how the weather patterns are changing over the years. The extended rainy season in Okinawa might have some implications for the region’s agriculture and tourism.
