Using data from June-October, we show that the temperature, humidity, and winds announce the arrival of the monsoon, with changes that amplify with elevation. The largest change is therefore at the summit, where we estimate that monthly mean air temperature increased by 5.5 °C between June and July to average -19.1 °C over the monsoon. Such warming takes temperatures into the realm of winter conditions on much lower mountains of the mid-latitudes, illustrated with the well-known Mount Washington observatory (1,916 m; New Hampshire, USA). Although other dangers of climbing Everest may be enhanced during the monsoon, the cold induced hazard is much reduced.
