One month forecast: High temperature trend continues nationwide; heavy precipitation expected on the Pacific side of eastern Japan and western Japan

Today, the 2nd (Thursday), the Japan Meteorological Agency announced the one-month forecast for April 4th to May 3rd.

The Pacific side of eastern Japan and western Japan will be susceptible to the effects of low pressure systems and fronts around the beginning of the period, and will experience more precipitation than normal. Okinawa and Amami are expected to be easily covered by high pressure because the gradient of atmospheric pressure is gentle.
The temperature at an altitude of approximately 1,500 meters is expected to be higher than normal nationwide, as westerly winds tend to flow further north than normal, making it more likely to be covered by warm air.



As a result, temperatures will remain high across the country over the next month.
From this weekend until the beginning of next week, many places will have higher than average temperatures, and the weather is expected to be as warm as May, especially in northern and eastern Japan. Even in central Tokyo, the highest temperature is expected to be 25 degrees Celsius on the 6th (Monday), making it the first summer day of the year. Widespread rain is expected over the weekend, but those planning to exercise indoors should take precautions against the heat.
The trend of high temperatures is expected to continue into the second half of Golden Week, with many days being warmer than normal, and it may be necessary to take measures against the heat during the Golden Week holidays.
Please be careful about your daily physical condition as the risk of heat stroke may increase when you are not yet used to the heat.
On the other hand, the cherry blossom front is moving smoothly into northern Japan, and even in northern Japan, many places are expected to bloom earlier than normal. It's a good idea to make your cherry blossom viewing plans early.

Due to the effects of low pressure and fronts, precipitation over the next month is expected to be higher than normal on the Pacific side of eastern Japan and western Japan, and at or above normal on the Sea of Japan side of eastern Japan.
The Pacific side of eastern Japan and western Japan have been less affected by low pressure and fronts since mid-November last year, so precipitation has been low. With heavy rainfall expected over the next month, the impact will be somewhat resolved, but it is possible that the effects of the low rainfall to date may remain.
In northern Japan, there are days when the weather is not clear during the first half of the period, but there are many sunny days in the second half.
