本日は札幌国際スキー場山頂で快晴。午前7時の山頂気温は18.6℃、山麓は21.6℃と、山頂と山麓で3℃の気温差がある。日中は快晴が続き、正午には山頂で22.5℃まで気温が上昇する見込み。風は概ね穏やかで、最大突風も8.4m/s程度と弱い。視程は20km以上と良好で、夏山ハイキングには最適な一日となる。
地面コンディションは、降水が全くないためドライ。積雪もゼロであり、夏山用の登山靴で問題なく歩行可能だ。アイゼンやチェーンスパイク、ストックも不要。行動中の体感気温は山頂で20℃前後と予想されるが、札幌国際スキー場は標高差があるため、山頂付近での休憩時や風が吹いた際に体感気温が下がることを考慮し、速乾性ベースレイヤーの上に薄手のフリースや長袖シャツ、防風性のアウター(ウィンドシェル)を携行すること。
雷のリスクは降水確率0%のため極めて低い。強風による行動制限の懸念もなく、低体温症のリスクも現在の気温水準では低い。自動リスク判定でも顕著な警戒値は検出されていないが、山岳行動は常に変化する。特に山頂付近は風の影響を受けやすく、体感温度が変わりやすい。
夕方18時以降は曇りに変わり、夜間にかけて気温は14℃台まで低下する。日中の快適なコンディションから一転、日没後は冷え込むため、行動が長引く場合は保温着の準備を怠らないこと。視程低下の懸念はないが、日中のうちに周辺の地形を確認し、余裕を持った行動を心がけるべきだ。

Today at Sapporo Kokusai Ski Resort, the summit is clear. At 7 AM, the summit temperature is 18.6℃, while the base is 21.6℃, indicating a 3℃ difference between the summit and the base. Clear skies are expected to continue throughout the day, with the summit temperature projected to rise to 22.5℃ by noon. Winds will remain generally light, with maximum gusts around 8.4m/s, posing no significant risk. Visibility is excellent, exceeding 20km, making it an ideal day for summer hiking.
Ground conditions are dry due to no precipitation and zero snow depth. Standard summer hiking boots are sufficient for walking. Crampons, microspikes, and trekking poles are not required. The perceived temperature at the summit is expected to be around 20℃ during activity. However, given the elevation difference at Sapporo Kokusai Ski Resort, be prepared for cooler conditions at the summit, especially during breaks or when exposed to wind. It is advisable to carry a quick-drying base layer, a thin fleece or long-sleeved shirt, and a windshell as an outer layer.
The risk of lightning is extremely low with a 0% chance of precipitation. There is no concern for strong winds restricting movement, and the risk of hypothermia is low at current temperature levels. No significant alerts were detected by the automated risk assessment, but mountain conditions can always change. Be particularly mindful that the summit area is more exposed to wind, which can affect perceived temperatures.
The weather is forecast to turn cloudy after 6 PM, with temperatures dropping to the mid-14℃ range overnight. While daytime conditions are comfortable, prepare for cooler temperatures after sunset if your activity extends into the evening. While there are no concerns about reduced visibility, confirm the surrounding terrain during daylight hours and plan your activities with ample time.
