2026年8月8日(土)・9日(日)・10日(月)の3日予報。47都道府県の代表都市を日本語と英語で読み、カードは表示時に最新データを取得します。土曜は本州から九州で真夏の暑さが続き、日差しの強い時間だけでなく、湿度の高い朝晩にも熱中症への備えが必要です。山沿いと内陸では、午後に積乱雲が急発達して局地的な雷雨となる可能性があります。日曜は雲の広がる地域が増え、短時間の強い雨や雷を伴う所がある見込みです。月曜は予報の不確実性がやや高まりますが、暑さと湿気が続く一方、前線や湿った空気の影響を受ける場所では雨具が役立ちます。沖縄・南西諸島と沿岸部では、天気だけでなく風、波、航空便・船便も確認してください。数値は代表都市の計画用データで、警報ではありません。気象庁の警報・注意報、熱中症警戒アラート、自治体の避難情報を最優先にしてください。

Japan.co.jp Weather Desk / Nationwide planning page for August 8–10, 2026, checked August 7 at 9:02 a.m. JST. Saturday keeps midsummer heat and humidity across much of Honshu, Shikoku and Kyushu, with heat precautions needed after sunset as well as during the day. Afternoon convection may bring sudden showers, lightning and locally intense rain, especially near mountains and inland areas. Sunday becomes cloudier in more regions, with a continued risk of brief heavy rain and thunderstorms. Confidence is lower by Monday, but the broad planning message remains heat plus humidity, with rain gear useful where fronts or moist air become influential. In Okinawa, the Nansei Islands and coastal districts, check wind, waves and air or sea transport as well as the sky forecast. The cards below request August 8–10 data from Open-Meteo whenever the page loads. They are representative-city guidance, not warnings; JMA and local governments remain authoritative for forecasts, alerts and emergency instructions.

大切なメモ:下のカードは、ブラウザでOpen-Meteoの3日予報を取得して更新します。気象庁の警報・注意報、土砂災害警戒情報、熱中症警戒アラート、台風情報、自治体の避難情報は必ず公式発表を確認してください。危険な暑さでは不要な外出や運動を減らし、夜間も冷房を使ってください。短時間の強い雨や雷雨では、地下道、増水した川、崖、木の下を避けてください。海や山へ出かける前には、風、波、雷、交通機関の最新情報も確認してください。
Important note: Cards update in-browser using Open-Meteo forecast data. Always check JMA and local governments for official forecasts, warnings, landslide information, heatstroke alerts, tropical-cyclone information and evacuation instructions. Reduce nonessential outdoor activity during dangerous heat and use cooling at night. During sudden heavy rain or thunderstorms, avoid underpasses, swollen rivers, steep slopes and isolated trees. Check wind, waves, lightning and transport updates before coastal or mountain travel.

Forecast source: This page was prepared for August 8–10 and checked on August 7 at 9:02 a.m. JST. It requests Open-Meteo daily forecast data in the browser for representative cities in all 47 prefectures, so card values can change whenever the page is loaded. Check the Japan Meteorological Agency’s official forecasts, warnings and advisories, tropical-cyclone map and early warning information, the Ministry of the Environment’s heatstroke alerts, and local-government instructions before acting.

Weather desk context: The three-day planning outlook emphasizes persistent midsummer heat and humidity, including warm nights, together with the possibility of isolated afternoon thunderstorms and short bursts of intense rain. Cloud and rain coverage can shift quickly where moist air, sea breezes, terrain and frontal boundaries interact. By Monday, location-specific confidence is lower than on Saturday, so the live cards and official updates matter more than a fixed national summary. Okinawa, the Nansei Islands, coastal districts and mountain areas require particular attention to wind, waves, lightning and transport conditions. Representative-city values do not describe an entire prefecture, are not official warnings and cannot predict local damage or evacuation orders.
