Nairobi at a glance
How elevation shapes the reading in Nairobi
Nairobi is about 5,525 ft (1,684 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 24.41 inHg (827 hPa) on a standard day, against 29.92 inHg at sea level.
The reading above is the altimeter setting from Nairobi/Kenyatta Intl (HKJK), 13 km (8 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 Nairobi with any other city.

Frequently asked questions
What is the barometric pressure in Nairobi today?
The live reading at the top of this page is the latest sea-level pressure reported by Nairobi/Kenyatta Intl (HKJK), 13 km (8 mi) from the city center. It updates about every 10 minutes; the graph shows the last 24 hours.
What is normal barometric pressure in Nairobi?
Weather reports for Nairobi 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 Nairobi read lower than the forecast?
Nairobi sits at about 5,525 ft (1,684 m). At that height the air above weighs less, so an uncorrected sensor reads around 24.41 inHg (827 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 Nairobi 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.
