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 Tucson: common questions
What is normal barometric pressure in Tucson?
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 759 m in Tucson typically reads around 925 hPa (27.33 inHg).
Why does my phone show a different pressure in Tucson 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 Tucson, that adjustment is about 88 hPa (2.60 inHg) under standard conditions, and it grows if you are on a higher floor or hill.
Is the barometric pressure in Tucson 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.
