On 16 January 2021, a team of Nepalese mountaineers claimed the last great prize of high altitude mountaineering with the first winter summit of K2. Here, we examine to what extent the weather on the “savage mountain” may have aided the intrepid climbers during their ascent. We find that, whilst the team had to endure brutal temperatures and winds earlier in the season, the arrival of an upper-level ridge on 16 January brought uncharacteristically high pressures and temperatures, but low winds. Notably, the cold hazard was still extreme by the standards of summit climbs of mountains above 8,000 m a.s.l., but uncharacteristically favourable for K2 in winter. Extraordinary ability therefore aligned with a weather window of opportunity to set up this moment of mountaineering history.
