Mexico City at a glance
How elevation shapes the reading in Mexico City
Mexico City is about 7,349 ft (2,240 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 22.78 inHg (772 hPa) on a standard day, against 29.92 inHg at sea level.
The reading above is the altimeter setting from Mexico City Intl (MMMX), 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 Mexico City with any other city.

Frequently asked questions
What is the barometric pressure in Mexico City today?
The live reading at the top of this page is the latest sea-level pressure reported by Mexico City Intl (MMMX), 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 Mexico City?
Weather reports for Mexico City 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 Mexico City read lower than the forecast?
Mexico City sits at about 7,349 ft (2,240 m). At that height the air above weighs less, so an uncorrected sensor reads around 22.78 inHg (772 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.
Is the pressure in Mexico City 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.
