Normal barometric pressure in Dallas
Dallas is close to sea level (about 128 m), so a barometer or phone sensor there typically reads around 998 hPa (29.47 inHg), only about 15 hPa below 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 128 m (standard-atmosphere estimate) | 998 | 29.47 | 749 |
Because the two values are close, local readings and weather reports in Dallas 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 Dallas: common questions
What is normal barometric pressure in Dallas?
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 Dallas averaged 1,016.1 hPa (30.01 inHg), and on 9 days out of 10 the daily average was between 1,007 and 1,028 hPa. A barometer measuring local pressure at about 128 m in Dallas typically reads around 998 hPa (29.47 inHg).
Why does my phone show a different pressure in Dallas 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 Dallas, that adjustment is about 15 hPa (0.45 inHg) under standard conditions, and it grows if you are on a higher floor or hill.
Is the barometric pressure in Dallas 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.
