West Japan and East Japan reach peak of cedar pollen dispersal

There will be many warmer than average days this week, and in western and eastern Japan where pollen dispersal is in full swing, there is a risk that cedar pollen will be dispersed in large amounts. In a wide range, it is expected that there will be many days with the highest “very high number” among the 4 ranks of scattering forecast. It can be said that the scattering of cedar pollen is just entering the peak season.

Pollen is starting to fly all over the Tohoku region, and there are days when it is expected to be “heavy” in the southern part of the Tohoku region, where the scattering has begun in earnest.

Scattering peak forecast of cedar and cypress

In areas where the pollen started to disperse a little earlier, there are already large amounts of dispersal, and the peak of cedar pollen in Kanto and Kyushu is expected to continue until the latter half of March. In the Hokuriku and Tohoku regions, cedar pollen is expected to peak in mid-March.

In the second half of March, cedar pollen dispersal peaks gradually, and cypress pollen dispersal increases from western Japan.

From late March to mid-April, we expect to reach the peak of cypress pollen dispersal mainly in western and eastern Japan. If the temperature stays high, the peak may be earlier than expected, so please be careful if you are sensitive to cypress pollen.

From around March 1 (Wednesday), the weather is expected to go downhill as the front passes from the Sea of ​​Japan, and rain is expected to fall in many places.

After the low pressure system passes, the cold air will move southward, but it will be temporary, and it is expected that there will be more days with high temperatures in the second half of the week.

The amount of cedar pollen scattered may increase suddenly on the day following it rains, on days when the temperature rises, and on days when the wind blows strongly.

Cedar pollen is already scattered in earnest in Kyushu, Kanto, Chugoku-Shikoku, and parts of the Tokai region, but the area where pollen is scattered will expand even further in the second half of the week, and it is possible that it will become a full-scale scattering in areas where the pollen has already started.
