Normal barometric pressure in Twin Falls
Twin Falls is a high-elevation city (about 1,138 m). Local air pressure there is typically around 884 hPa (26.10 inHg), roughly 13% lower than at sea level.
| Reference | hPa | inHg | mmHg |
|---|---|---|---|
| Standard sea-level pressure (used in weather reports) | 1,013.25 | 29.92 | 760 |
| Typical surface pressure at about 1,138 m (standard-atmosphere estimate) | 884 | 26.10 | 663 |
Weather reports still show sea-level pressure near 1,013 hPa (29.92 inHg), so a local barometer reading far below that is expected at this elevation and is not, by itself, a sign of stormy weather.
Reading the pressure
Sea-level pressure allows comparison between places at different elevations. Surface pressure represents pressure at the modelled ground elevation. A rising or falling value describes a trend; it is not a complete weather forecast.
Barometric pressure in Twin Falls: common questions
What is normal barometric pressure in Twin Falls?
For weather comparisons, normal sea-level pressure is 1,013.25 hPa (29.92 inHg, 760 mmHg). Readings above it are higher than standard and readings below it are lower. A barometer measuring local pressure at about 1,138 m in Twin Falls typically reads around 884 hPa (26.10 inHg).
Why does my phone show a different pressure in Twin Falls than the weather report?
Phone sensors and household barometers measure pressure where you are, while weather reports adjust readings to sea level so places can be compared. In Twin Falls, that adjustment is about 129 hPa (3.82 inHg) under standard conditions, and it grows if you are on a higher floor or hill.
Is the barometric pressure in Twin Falls high or low today?
When live data loads, compare the current sea-level reading above with 1,013 hPa (29.92 inHg). The three-hour change and the seven-day trend usually say more about changing weather than a single value. Normal, high, and low pressure explained.
