今日の十勝岳は快晴が広がり、山頂の視程は20km以上と遠くまで見渡せる。望岳台コースからの登高では、活火山特有の雄大な景観を存分に楽しめるだろう。
山頂の朝7時における体感は0.2℃。日中にかけて気温は上昇し、正午には7.2℃、15時には7.7℃まで上がる見込みだ。風は比較的穏やかだが、森林限界を越える稜線では、正午頃に突風が8.5m/sに達する時間帯があるため、体感温度の低下に注意が必要となる。
積雪はなく、地面はドライコンディション。岩稜露出が主となるため、滑落に注意し、足元をしっかり確認しながら進むこと。特に火山ガス濃度が高い新噴火口周辺では、風向きによってはガスに注意が必要だ。防寒着は速乾性のベース、保温性のミッド、防風・防水性のアウターの3枚重ねを基本とし、休憩時にはさらに保温着を羽織る準備を。手袋や帽子も忘れずに携行すること。低体温症のリスクは日中の活動中には低いが、休憩時や朝晩の冷え込みには十分な備えが必要だ。
日没後は気温が急速に低下し、深夜には0℃前後まで冷え込む。夜間の行動は避け、日中の明るい時間帯に下山を完了させる計画とすること。雷の発生は予測されておらず、行動中止を要するような強風も予報されていない。

Tokachidake presents clear skies today with excellent visibility exceeding 20km from the summit. Hikers ascending via the Bougakudai Course will be able to fully enjoy the magnificent scenery characteristic of this active volcano.
At 7 AM, the summit's feels-like temperature was 0.2°C. Temperatures are expected to rise throughout the day, reaching 7.2°C by noon and 7.7°C by 3 PM. While winds are generally light, gusts up to 8.5 m/s are anticipated around midday, particularly on exposed ridges above the tree line. Proper layering is crucial to manage the feels-like temperature effectively.
There is no snow cover, and ground conditions are dry with predominantly exposed rock. Hikers should be mindful of their footing to prevent slips and falls. Near the Shin-funkakou (New Crater), elevated volcanic gas concentrations can be a concern depending on wind direction, so remain vigilant. Essential clothing includes a moisture-wicking base layer, an insulating mid-layer, and a windproof/waterproof outer shell. Carry an additional warm layer, such as a down jacket, for breaks and colder periods. Gloves and a hat are also recommended. The risk of hypothermia is low during active daytime hiking, but it significantly increases during static periods or in the early morning and late evening when temperatures approach freezing.
Temperatures will drop rapidly after sunset, falling to around 0°C by midnight. Plan your descent to be completed during daylight hours to avoid the cold and ensure safety. No lightning activity or winds severe enough to necessitate halting operations are currently forecast.
