槍ヶ岳：槍ヶ岳穂先は午前中勝負午後から天候下り坂

午前中の槍ヶ岳は快晴が続き、視界は20km以上と良好だ。山頂現況気温1.8℃、体感は-1.4℃だが、12時頃には突風を伴い体感-9.7℃まで冷え込む。山麓との気温差は約10℃あり、山頂の寒さを甘く見ないこと。適切な防寒対策が必須となる。日中の槍ヶ岳は岩稜が露出しており、概ねドライコンディションが続く。穂先の鎖場や梯子の通過は午前中のうちに済ませたい。午後15時頃から弱い霧雨が始まり、岩が濡れて滑りやすくなるため、山頂直下の落石や滑落リスクが増す。濡れた岩場での行動は細心の注意を払うこと。必要な防寒レイヤリングは、吸湿速乾性ベースレイヤー、フリース等のミッドレイヤー、防水透湿性シェルアウター。停滞時や風が強まる時間帯には薄手ダウンジャケットを重ね着する。手袋、帽子も必須だ。雨具は午後からの霧雨、夜間の雪に備え必ず携行すること。アイゼンやチェーンスパイクは不要。雷のリスクは低いが、午後から天候は下り坂。夜間21時頃から弱い雪が降り始め、深夜0時頃には積雪0.5cm程度の雪となる見込み。低体温症のリスクは常にあるため、行動中はこまめな水分・行動食補給を心がけ、無理のない計画で行動すること。
