伊吹山山頂は現在、強い雨が降り体感気温は10.2℃。山麓との気温差は約8℃と大きく、標高が上がるにつれて体感は急激に低下する。午前9時までは強い雨が続き、降水量はさらに増える。表登山道(上野登山口からのルート)は広範囲で深い泥濘状態となる。防水性の高い登山靴と上下セパレートの雨具は必須、泥濘対策としてゲイターの着用も推奨する。
体感気温は日中を通して10℃前後で推移する。特に午後3時には突風17.9m/sが予報されており、気温14.5℃でも体感はさらに下がる。ベースレイヤーは速乾性、ミッドレイヤーはフリースや薄手のダウン、アウターには防水透湿性のレインウェアを着用し、濡れることによる低体温症に厳重な警戒が必要だ。現況の視程は2.6kmだが、強い雨と高い湿度により、山頂付近では霧が発生しやすく、伊吹山特有のリスクである霧での道迷いに注意が必要となる。
午前中の強い雨と泥濘、午後の強風を考慮すると、本日の登山は非常に厳しいコンディションだ。特に表登山道の一気登りは、泥濘による足元の不安定さと体力の消耗が著しい。初心者は今日の行動を控え、経験者も細心の注意を払い、無理のない計画を立てること。雷の兆候は見られないが、強風による行動困難や低体温症のリスクは高い。
午後からは天候が回復し、12時には雨が止み、15時にはほぼ晴れとなる予報だ。しかし、夕方にかけても突風は17m/s前後で吹き荒れるため、風対策は継続して必要となる。

Currently, Mount Ibuki summit experiences heavy rain with a felt temperature of 10.2 degrees Celsius. There is a significant temperature difference of about 8 degrees Celsius between the summit and the base, indicating a rapid drop in perceived temperature with altitude gain. Heavy rain is expected to continue until 9 AM, further increasing precipitation. The Omote Tozan-do (Ueno Tozanguchi route) will be extensively muddy. Waterproof hiking boots and a separate rain suit are essential, and gaiters are recommended for mud protection.
The felt temperature will remain around 10 degrees Celsius throughout the day. A strong gust of 17.9 m/s is forecasted for 3 PM, which will further lower the felt temperature even with an actual air temperature of 14.5 degrees Celsius. Wear a quick-drying base layer, a fleece or thin down jacket as a mid-layer, and a waterproof-breathable rain jacket as an outer layer. Be extremely vigilant against hypothermia due to getting wet. Although current visibility is 2.6 km, heavy rain and high humidity make fog formation highly likely near the summit, posing a significant risk of getting lost in the fog, a unique hazard of Mount Ibuki.
Considering the heavy rain and muddy conditions in the morning, and strong winds in the afternoon, today's climbing conditions are very challenging. The steep ascent of the Omote Tozan-do will be particularly demanding due to unstable footing from mud and significant physical exertion. Novice climbers should refrain from hiking today, and even experienced climbers must proceed with extreme caution and a conservative plan. While no lightning is forecasted, the risks of strong winds hindering movement and hypothermia are high.
Weather is expected to improve in the afternoon, with rain stopping by 12 PM and mostly clear skies by 3 PM. However, strong gusts of around 17 m/s will persist into the evening, requiring continued wind protection.
