週末，臺灣仍受到太平洋高壓影響，整體天氣趨於穩定，各地以晴到多雲為主，高溫普遍落在33至35度，西部盆地與內陸地區更有機會飆升至36至37度；午後對流發展大多侷限於山區，降雨範圍零散，但若前往深山溪谷活動，仍要留意午後天氣變化；花東地區及恆春半島因位處在迎風面，將偶有局部短暫陣雨。整體來說，天氣相對穩定，高溫炎熱，提醒民眾外出務必做好防曬，多補充水分，避免中暑或熱傷害。

下週，預計太平洋高壓勢力略有減弱，臺灣位處高壓西南至南側邊緣，大環境仍以偏東風或東南風為主，期間隨東風波動偶有水氣接近，迎風面的東半部仍有地形性降雨機會，西半部則維持晴到多雲；午後各地山區及近山平地仍易有熱對流發展，帶來短暫雷陣雨。整體天氣型態仍偏向夏季型，白天氣溫持續偏高，西部地區高溫仍可能達36度或以上。

另外，菲律賓附近有一熱帶擾動逐漸往西方移動，預測週末至下週前期進入南海後朝越南方向發展，期間雖有機會增強為熱帶性低氣壓或颱風，但對臺灣沒有直接影響。

未來展望，八月底至九月初南方洋面仍存在新的熱帶系統生成可能，且在太平洋高壓勢力偏北的情況下，無法完全排除熱帶系統往臺灣靠近的機率，建議持續關注最新氣象資訊，目前距離時間仍久，預報不確定性高，後續變化仍須觀察。整體來看，短期內臺灣以高溫炎熱為主要特徵，午後山區熱對流降雨，戶外活動請加強防曬、防熱。
