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 Nashville: common questions
What is normal barometric pressure in Nashville?
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. From 2021 to 2025, sea-level pressure in Nashville averaged 1,017.8 hPa (30.05 inHg), and on 9 days out of 10 the daily average was between 1,009 and 1,028 hPa. A barometer measuring local pressure at about 170 m in Nashville typically reads around 993 hPa (29.32 inHg).
Why does my phone show a different pressure in Nashville 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 Nashville, that adjustment is about 20 hPa (0.60 inHg) under standard conditions, and it grows if you are on a higher floor or hill.
Is the barometric pressure in Nashville 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.
