How elevation shapes the reading in Natal
Natal is about 105 ft (32 m) above sea level. That is close to sea level, so the pressure you stand in and the sea-level figure in the forecast are nearly the same.
The reading above is the altimeter setting from Natal/Severo Arpt (SBNT), 14 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 Natal with any other city.

Frequently asked questions
What is the barometric pressure in Natal today?
The live reading at the top of this page is the latest sea-level pressure reported by Natal/Severo Arpt (SBNT), 14 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 Natal?
Weather reports for Natal 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 Natal read lower than the forecast?
Natal is close to sea level (about 105 ft), so absolute and sea-level pressure differ by only about 0.11 inHg (4 hPa). A larger gap usually means the barometer needs to be calibrated against the reading on this page.
Where can I see a 7-day barometric pressure graph for Natal?
The graph on this page shows the last 7 days of hourly sea-level pressure from SBNT, 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 Natal 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.
