Frequently asked questions
What is the barometric pressure in Tupelo today?
The live reading at the top of this page is the latest sea-level pressure reported by Tupelo Rgnl (KTUP), 6 km (4 mi) from the city center. It updates about every 10 minutes; the graph shows the last 24 hours.
What is normal barometric pressure in Tupelo?
Weather reports for Tupelo 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 Tupelo read lower than the forecast?
Tupelo is close to sea level (about 279 ft), so absolute and sea-level pressure differ by only about 0.30 inHg (10 hPa). A larger gap usually means the barometer needs to be calibrated against the reading on this page.
Where can I see a 7-day barometric pressure graph for Tupelo?
The graph on this page shows the last 7 days of hourly sea-level pressure from KTUP, with each day's high and low in the table below it. Its sharpest fall usually marks a front or storm passing through.
