宮之浦岳：宮之浦岳穏やかな晴天。稜線は快適

宮之浦岳は現在快晴、山頂気温16.7℃、体感17.5℃と快適な状況です。風はほぼ無風に近く、視程3.6kmで周囲の展望も良好です。日中にかけて気温は18℃前後で推移し、風も最大突風6.2m/s程度と弱く、穏やかな登山日和が続くでしょう。午前中はほぼ晴れ、午後には薄曇りとなりますが、降水確率は低い状態です。地面コンディションは、降水予報がないため基本的にドライと推測されます。しかし宮之浦岳は年4000mmを超える異常な多雨地帯です。過去の降水状況によっては、花之江河湿原周辺や沢沿いには湿った箇所やぬかるみが残っている可能性も考慮し、足元には注意が必要です。装備としては、アイゼンやチェーンスパイクは不要です。万一の天候変化に備え、軽量な雨具は携行してください。体感気温は日中を通じて18℃前後で推移するため、ベースレイヤーには速乾性のTシャツ、ミッドレイヤーには薄手のフリースや化繊ジャケット、アウターには防風性のある軽量シェルがあれば十分です。行動中は暑くなるため、着脱しやすいレイヤリングを心がけてください。雷や強風のリスクは低く、低体温症の懸念も小さいですが、夜間は14.9℃まで冷え込むため、停滞する場合は防寒対策を怠らないでください。
