Frequently asked questions
What is the barometric pressure in Campinas today?
The live reading at the top of this page is the latest sea-level pressure reported by Campinas/Viracopos Arpt (SBKP), 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 Campinas?
Weather reports for Campinas 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 Campinas read lower than the forecast?
Campinas sits at about 2,251 ft (686 m). At that height the air above weighs less, so an uncorrected sensor reads around 27.57 inHg (934 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.
Where can I see a 7-day barometric pressure graph for Campinas?
The graph on this page shows the last 7 days of hourly sea-level pressure from SBKP, 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 Campinas 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.
