Altitude and oxygen
Pathibhara Temple: altitude and oxygen
Pathibhara Temple stands at 12,444 ft (3,793 m) above sea level. The air pressure there is about 633 hPa against 1,013 hPa at sea level, so a breath holds roughly 62% of the oxygen the same breath holds at the coast — the equivalent of breathing 13.1% oxygen instead of 20.9%. Air is still 20.9% oxygen up there; there is simply less air. In the standard atmosphere the temperature at that height is -10 °C (14 °F), which is a modelled figure rather than a forecast — a clear Himalayan morning is routinely colder.

Flights that land here are on the ground for about 45 minutes. That is a published figure, and it is short by design — a helicopter tour reaches this height in minutes rather than the days a trek takes.
These figures describe the air, not anybody’s response to it. How a person is affected by height depends on the person, on how fast they got there and on how long they stay — a helicopter reaches these altitudes in minutes, which is a different exposure from a trek that takes days. If you have a heart or lung condition, are pregnant, or are travelling with young children or elderly parents, speak to a doctor before you book and tell the operator when you do: several carry supplemental oxygen and all of them plan the ground time around who is on board. Pressure and temperature are from the International Standard Atmosphere, which is a model — the real morning at this height is frequently colder and thinner still.

Asked about this site
Pathibhara Temple, in detail
- How high is Pathibhara Temple?
- Pathibhara Temple is 12,444 ft above sea level, which is 3,793 m. That figure is the surveyed elevation of the landing site itself rather than of the surrounding terrain, which is why it can differ from the height quoted for a nearby summit or village.
- How much oxygen is there at Pathibhara Temple?
- Air at Pathibhara Temple is 20.9% oxygen, exactly as it is at sea level, but at about 633 hPa rather than 1,013 hPa — so a breath holds roughly 62% of the oxygen the same breath holds at the coast. That is the equivalent of breathing 13.1% oxygen at sea level.
- How cold is it at Pathibhara Temple?
- In the International Standard Atmosphere the temperature at 3,793 m is -10 °C (14 °F). That is a modelled figure, not a forecast and not a measurement: a clear Himalayan morning at this height is routinely colder than the model, and wind makes it colder still on exposed ground.
- How long do helicopter flights stay on the ground at Pathibhara Temple?
- About 45 minutes, on the itineraries operators publish for the routes that land here. Ground time at height is kept deliberately short, and the exact figure is set on the day by the pilot against the weather, the aircraft's weight and who is on board.

Leave a number. A dispatcher rings back and plans the ground time, the oxygen and the landing around who is on board — the part of a Himalayan flight that gets decided on the phone rather than in a form.
