自開始登8000米開始後一年開始嘗試以更困難的季節攀登，因為風及溫度都是非常具有挑戰性的額外因素，天候狀況更是難以預測。K2 位處西風帶的南緣，在喀拉崑崙的群山中是獨立的山體，因而受到風與天氣的影響特別顯著。再加上8611公尺的超高海拔，這也讓冬季的K2擁有更低的氣溫，高營地還有時速每小時80公里以上的強烈風勢，攀登條件非常嚴苛。
冬攀K2是全球14座8000公尺山峰裡最後一座一直到去年才有一支尼泊爾團隊首登成功，可見其難度。
直至今日，目前全球尚未有女性以及非尼泊爾人在此季節登頂。
Since the start of climbing 8000-meter peaks, climbers have been attempting to climb in even more difficult seasons due to challenging factors such as wind and temperature, not to mention unpredictable weather conditions. K2 is located on the southern edge of the westerlies in the Karakoram range, and as a solitary mountain, it is particularly affected by wind and weather. In addition, with an altitude of 8611 meters, winter on K2 brings even lower temperatures and extremely harsh climbing conditions, including winds that can reach speeds of over 80 kilometers per hour at high camps.
Winter climbing on K2 is considered the most difficult among the 14 peaks over 8000 meters, and only last year did a Nepalese team succeed in making the first winter ascent, highlighting its difficulty. To this day, no woman or non-Nepalese climber has summited K2 in this season.
