Golden Week (GW) will start this weekend. Weathernews has announced the weather forecast for April 29th (Friday) to May 8th (Sunday).

This year’s Golden Week holidays make it easier to pass through low pressure systems and troughs in a short cycle. The sunny weather tends to be short-lived, and it is possible that it will rain extensively. The temperature is expected to remain at or slightly higher than normal.

Trends in weather and temperature

From late April to early May, it is predicted that the high pressure will tend to be stronger than usual in the Pacific Ocean east of Japan, and it is expected that warm and moist air will continue to flow into the Japanese archipelago from the south.

It is expected that there will be rainy days due to the influence of this moist air. It can also be a widespread and heavy rain. Also, if you are planning leisure in mountains or rivers where the weather changes easily even on a sunny day, be sure to check the weather forecast carefully in case of lightning strikes or flash floods.

In addition, cold air easily flows from the early to middle stages of Golden Week, mainly in northern Japan, and it is unlikely that the temperature will be extremely high in western and eastern Japan. Warm air flows in from the south at the end of Golden Week, and when it is sunny, it may be as hot as 30 degrees Celsius. It seems good to take measures against heat and ultraviolet rays with a hat and diligent hydration. At this time of year, the temperature difference between morning and evening and daytime becomes large. It is recommended that you prepare something to put on when you go out, as it will make you sick easily.

Northern Japan

Umbrellas are likely to come into play in northern Japan. From May 1st (Sun) to 2nd (Mon) and 4th (Wed) to 5th (Thurs), it is expected that it will rain easily due to the influence of the trough accompanied by cold air. In addition, cold air easily flows from the first half to the middle of GW, and the temperature is expected to be about the same as normal or slightly lower.

In Hokkaido, it seems that you can enjoy the cherry blossoms in full bloom during the Golden Week period in southern Hokkaido and Sapporo city. It seems that there are many places in Central Hokkaido, Northern Hokkaido, and Eastern Hokkaido that are in full bloom in the latter half of Golden Week.

Eastern Japan

In eastern Japan, it is expected that there will be many places where it will rain due to the influence of low pressure around April 29 (Friday) and May 1 (Sunday). The end of the period is expected to be sunny on some days, but it can also be cloudy or rainy under the influence of moist air.

It is expected that the high temperature tendency before the Golden Week holidays will settle down once, but it seems that there will be days when it feels hot and humid in the daytime.

West Japan

In western Japan, it is expected to rain extensively around April 29 (Friday) and May 1 (Sunday). On other days, it is expected that there will be more cloudy and rainy days in southern areas such as southern Kyushu and Shikoku, and there is a risk that rainfall will increase during the period in southern Kyushu. Please be careful about heavy rain just in case.

It is not expected to be extremely hot when it rains, but it is expected that the temperature will be high on many days despite the lack of sunlight.

Okinawa / Amami

In Okinawa and Amami, there are many cloudy and rainy days throughout the Golden Week period, and it is expected that the weather will be rainy and rainy every day, especially after May 1st (Sun). The rainy season starts from the beginning to the middle of May every year, but it seems that the rainy season will continue during the Golden Week period.

The temperature is about the same as normal, and it seems that the days will continue to be dull.

Choose clothes that match the temperature

◆ 25 ℃ or higher: Short-sleeved shirt
It’s hot in the sun, and if you walk a little, you may get sweaty. The short sleeves feel comfortable.

◆ Less than 25 ℃: Long-sleeved shirt
The breeze feels a little cool, and it’s safe to have a long-sleeved shirt.

◆ Less than 20 ℃: Cardigan
Wearing vests, thin cardigans, etc. on long-sleeved shirts is useful.

◆ Less than 16 ℃: Sweater
I feel warmth in the sun. Go out lightly with a soft sweater.
