Frequently asked questions
What is the barometric pressure in San Bernardino today?
The live reading at the top of this page is the latest sea-level pressure reported by San Bernardino Intl (KSBD), 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 San Bernardino?
Weather reports for San Bernardino 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 San Bernardino read lower than the forecast?
San Bernardino is close to sea level (about 1,053 ft), so absolute and sea-level pressure differ by only about 1.12 inHg (38 hPa). A larger gap usually means the barometer needs to be calibrated against the reading on this page.
