Frequently asked questions

What is the barometric pressure in Tuscaloosa today?

The live reading at the top of this page is the latest sea-level pressure reported by Tuscaloosa Rgnl (KTCL), 4 km (3 mi) from the city center. It updates about every 10 minutes; the graph shows the last 24 hours.

What is normal barometric pressure in Tuscaloosa?

Why does a barometer in Tuscaloosa read lower than the forecast?

Tuscaloosa is close to sea level (about 223 ft), so absolute and sea-level pressure differ by only about 0.24 inHg (8 hPa). A larger gap usually means the barometer needs to be calibrated against the reading on this page.
