How elevation shapes the reading in Logan
Logan is about 4,534 ft (1,382 m) above sea level. That is high enough that the air pressure you actually stand in is well below the figure in the forecast: about 25.33 inHg (858 hPa) on a standard day, against 29.92 inHg at sea level.
The reading above is the altimeter setting from Logan/Cache Arpt (KLGU), 6 km (4 mi) from the city center. It is the station’s measured pressure corrected to sea level, which is the number weather reports, apps and TV forecasts use, so you can compare Logan with any other city.

Frequently asked questions
What is the barometric pressure in Logan today?
The live reading at the top of this page is the latest sea-level pressure reported by Logan/Cache Arpt (KLGU), 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 Logan?
Weather reports for Logan 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 Logan read lower than the forecast?
Logan sits at about 4,534 ft (1,382 m). At that height the air above weighs less, so an uncorrected sensor reads around 25.33 inHg (858 hPa) on a standard day. Forecasts correct that to sea level. Set a home barometer to the sea-level value on this page, or use the station pressure line for an uncorrected comparison.
Where can I see a 7-day barometric pressure graph for Logan?
The graph on this page shows the last 7 days of hourly sea-level pressure from KLGU, with each day's high and low in the table below it. Its sharpest fall usually marks a front or storm passing through.
Is the pressure in Logan 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.
