Normal barometric pressure in Jacksonville
Jacksonville is at about sea level (about 5 m), so a barometer or phone sensor there typically reads around 1,013 hPa (29.90 inHg), within about 1 hPa of the sea-level figures in weather reports.
| Reference | hPa | inHg | mmHg |
|---|---|---|---|
| Standard sea-level pressure (used in weather reports) | 1,013.25 | 29.92 | 760 |
| Typical surface pressure at about 5 m (standard-atmosphere estimate) | 1,013 | 29.90 | 760 |
Because the two values are almost identical, local readings and weather reports in Jacksonville are easy to compare directly.

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 Jacksonville: common questions
What is normal barometric pressure in Jacksonville?
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 Jacksonville averaged 1,017.7 hPa (30.05 inHg), and on 9 days out of 10 the daily average was between 1,011 and 1,026 hPa. A barometer measuring local pressure at about 5 m in Jacksonville typically reads around 1,013 hPa (29.90 inHg).
Why does my phone show a different pressure in Jacksonville 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 Jacksonville, which is at about sea level, the two values are within about 1 hPa (0.03 inHg) under standard conditions, and the gap grows if you are on a higher floor or hill.
Is the barometric pressure in Jacksonville 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.
