白山山頂は薄曇り、体感気温は7.7℃。山麓との気温差は9.2℃と大きく、標高による冷え込みを実感する。日中は薄曇りからほぼ晴れへ移行し、12時には気温11.2℃まで上昇する見込み。風は終日穏やかで、日中の行動は比較的快適に進められるだろう。
地面は積雪がなくドライが基本となる。しかし、「砂防新道」のような利用者が多いルートでは、日中の気温上昇や早朝の湿気で部分的にウェットや泥濘となる箇所も予想される。登山靴の選択と足元に注意が必要だ。アイゼンやチェーンスパイクは不要。雨具、防寒着、手袋、帽子は必ず携行すること。
午後は15時頃から再び曇りとなり、降水確率は98%と高いが降水量は0mm予報。これは濃いガスや霧が発生し、視界不良となる可能性を示唆する。「御前峰」や「大汝峰」といった「三峰」の稜線では、道迷いのリスクが増す。早めの行動開始で、午前中の視界が良い時間帯に主要な区間を通過したい。雷、強風のリスクは低いが、低体温症対策として止まった際の防寒は怠らないこと。
夜間は快晴から薄曇りへ移行し、気温は7℃前後まで冷え込むが風は弱い。

Conditions generally good — Conduct standard mountain safety measures
Shirayama summit currently experiences light cloud cover with a feels-like temperature of 7.7℃. There's a significant 9.2℃ difference from the base, emphasizing the elevation's cooling effect and requiring proper preparation. Conditions are expected to transition from light cloud to mostly sunny by midday, with temperatures reaching 11.2℃ around 12:00. Winds will remain light throughout the day, with gusts up to 7m/s, making daytime activities relatively comfortable and pleasant for ascending.
Ground conditions are primarily dry, with no snow cover reported. However, on heavily trafficked routes like the "Sabou Shindo" trail, expect some sections to become wet or muddy due to daytime warming and early morning moisture. Appropriate hiking footwear with good grip is essential, and vigilance for slippery footing is advised, especially on descent. Crampons or microspikes are not necessary for today's conditions. Always carry waterproof outerwear, warm mid-layers, gloves, and a hat to adapt to changing mountain conditions.
Cloud cover is forecast to return around 15:00, with a 98% chance of precipitation but 0mm of rainfall. This indicates a high likelihood of dense fog or mist, potentially leading to poor visibility. On exposed ridges of the "Three Peaks" such as "Gozen-mine" and "O-nanji-mine," the risk of disorientation and getting lost increases significantly under such conditions. It is strongly recommended to start early to complete critical sections during the morning's better visibility. While the risk of thunderstorms and strong winds is low, be prepared for hypothermia if you stop for extended periods, even in mild temperatures, by adding layers.
Overnight, the weather will shift from clear skies to light cloud, with temperatures dropping to around 7℃, but winds will remain light, offering a calm evening.
