2027年日本春季花粉飛散預測:西日本增加、東日本減少

日本氣象公司公布預測,九州、中國、四國地區花粉量恐大幅增加,關東與東北地區則顯著減少。

Quick Look

日本氣象公司公布2027年春季花粉預測,呈現「東少西多」趨勢。受去年夏季氣候影響,九州、中國、四國地區花粉量預計增加,其中宮崎縣恐達今年2.05倍;關東與東北地區則顯著減少,東北地區預估僅為今年的3成。

Why It Matters

花粉量受前一年夏季日照與氣溫影響,日照充足且氣溫高會促進雄花生長。花粉飛散量通常呈現一年多、一年少的交替特性。

日本氣象公司10月1日公布2027年春季花粉飛散預測,呈現「東邊少、西邊多」的趨勢。北海道到近畿地區的花粉量將比2026年減少,九州、中國、四國地區則會增加。

日本氣象公司指出,花粉量的關鍵在於前一年夏天的日照與氣溫。日照充足、氣溫越高,越能促進隔年花粉來源的雄花生長。今年夏天東日本日照時間低於平均,氣溫也比往年低,反觀西日本晴天多、氣溫偏高,加上花粉本就有「一年多、一年少」交替的特性,今年北日本、東日本、近畿量多,西日本量少,明年將反轉。

預估明年春季,關東地區花粉量僅為今年的5成,東北地區更僅剩3成左右,大幅減少;但九州等地則會達到1.5倍以上,成為重災區。

若以都道府縣來看,差距更明顯,明年春季,青森縣僅剩今年的0.16倍、東京0.34倍、京都0.43倍;相對地,宮崎縣飆至2.05倍、大分1.87倍、山口1.82倍。東日本民眾可稍鬆口氣,西日本民眾仍需提早準備抗過敏措施。
