日本の最高気温41.8℃を伊勢崎市で観測！観測史上いちばん暑い夏に

Japan's New Heat Record and Its Hottest Summer

音声・ゲームはこちらから

1A thermometer in Isesaki, Gunma Prefecture, read 41.8 degrees Celsius at 2:26 p.m. on August 5, 2025. It was the highest temperature ever officially recorded in Japan. The old national record had stood for only a week. A city in Hyogo Prefecture had reached 41.2 degrees on July 30.

2The heat was not limited to one city. That day, 14 observation points in five prefectures hit 40 degrees or more, the largest number on a single day since records began. Heatstroke alerts were issued in almost every prefecture. People were urged to use air conditioners and avoid going outside during the day.

3After the season ended, the Japan Meteorological Agency confirmed a new record for the whole summer. The average temperature from June to August was 2.36 degrees above normal. It was the hottest summer since statistics started in 1898. The previous record summers, in 2023 and 2024, were 1.76 degrees above normal.

4Over the year, temperatures of 40 degrees or higher were recorded at 30 locations in 13 prefectures. These readings came on nine different days. That was the largest number of locations since comparable data began in 2010.

5The agency said the westerly jet stream flowed farther north than usual, bringing warm air over Japan. June and July both set records for their months. August was 1.84 degrees above normal, the second-highest figure for that month. Of 153 weather stations, 132 recorded their hottest summer on record.

全文訳

12025年8月5日午後2時26分、群馬県伊勢崎市の温度計は41.8℃を示しました。これは日本で公式に記録された中で最も高い気温でした。それまでの国内記録は、わずか1週間しか保たれていませんでした。7月30日に兵庫県の市が41.2℃を記録したばかりだったのです。

2暑さは1つの市にとどまりませんでした。その日、5つの府県の14地点で40℃以上となり、1日の数としては統計開始以来最多となりました。ほぼすべての都道府県で熱中症の警戒情報が出されました。人々はエアコンを使い、日中の外出を控えるよう強く呼びかけられました。

3夏が終わると、気象庁は夏全体でも新記録になったことを確認しました。6月から8月の平均気温は、平年より2.36℃高くなりました。1898年に統計が始まって以来、最も暑い夏でした。それまでの記録だった2023年と2024年の夏は、平年より1.76℃高い程度でした。

4この年は、13の府県の30地点で40℃以上の気温が記録されました。これらの記録は、9つの異なる日に観測されました。これは比較できるデータがそろう2010年以降で、最も多い地点数でした。

5気象庁は、偏西風がいつもより北を流れ、日本に暖かい空気を運んできたと説明しました。6月と7月は、どちらもその月としての記録を更新しました。8月は平年より1.84℃高く、8月としては2番目に高い数字でした。153の気象観測所のうち132か所で、観測史上最も暑い夏となりました。

文法ポイント：過去完了（had + 過去分詞）

過去のある時点までに起きていたことを表す。本文の the old national record had stood for only a week は「8月5日の時点で、前の記録は1週間しか続いていなかった」という意味。
