Frequently asked questions
What is the barometric pressure in Fresno today?
The live reading at the top of this page is the latest sea-level pressure reported by Fresno/Yosemite Intl (KFAT), 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 Fresno?
Weather reports for Fresno 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 Fresno read lower than the forecast?
Fresno is close to sea level (about 308 ft), so absolute and sea-level pressure differ by only about 0.33 inHg (11 hPa). A larger gap usually means the barometer needs to be calibrated against the reading on this page.
Is the pressure in Fresno 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.
