Normal: 29.80 – 30.20 inHg
About 1009–1023 hPa. Weather can go either way, so the 3-hour trend is the better guide.

Below about 1009 hPa. Rising air under low pressure builds clouds; expect wind and rain, especially if the pressure keeps falling.
Frequently asked questions
What is the barometric pressure in Dallas today?
The live reading at the top of this page is the latest sea-level pressure reported by Dallas-Ft Worth Intl (KDFW), 24 km (15 mi) from the city center. It updates about every 10 minutes; the graph shows the last 24 hours.
What is normal barometric pressure in Dallas?
Weather reports for Dallas use sea-level pressure, so “normal” is the same as anywhere: about 29.92 inHg (1013 hPa), with most days between 29.60 and 30.30 inHg (1002–1026 hPa). Readings above 30.20 inHg are high pressure; below 29.80 inHg is low pressure.
Why does a barometer in Dallas read lower than the forecast?
Dallas is close to sea level (about 420 ft), so absolute and sea-level pressure differ by only about 0.45 inHg (15 hPa). A larger gap usually means the barometer needs to be calibrated against the reading on this page.
Is the pressure in Dallas rising or falling?
See the trend badge under the reading: it compares the latest report with the one three hours earlier. Falling pressure usually means clouds, wind or rain on the way; rising pressure means clearing and more settled weather.
