Conditions on the upper mountain are hostile in ways that are mostly about air pressure. At the summit, atmospheric pressure is about a third of that at sea level, so each breath delivers roughly a third of the oxygen. Above about 8,000 m — the '''death zone''' — the body cannot acclimatise and deteriorates continuously; without supplementary oxygen, most people can survive there for hours, not days.+Conditions on the upper mountain are hostile in ways that are mostly about air pressure.

Winter winds on the summit routinely exceed 160 km/h as the jet stream touches the peak, and temperatures fall below −35 °C. The narrow calm before and after the summer monsoon produces the short climbing seasons in May and, less often, September.Winter winds on the summit routinely exceed 160 km/h as the jet stream touches the peak, and temperatures fall below −35 °C.
