How much the pressure changes in Bauru
In Bauru the pressure hardly changes from one day to the next. All year round a typical day’s change is about 1.1 hPa.
Does the pressure change a lot in Bauru?
Bauru, like about 46 out of every 100 large cities, almost never has a change of more than 10 hPa from one day to the next.
Each dot stands for up to 20 cities with 100,000 people or more. The first column is much taller than shown. Cities higher than 1,000 m are left out, and so are smaller cities within 15 km of a bigger one, unless they are capitals, so that suburbs are not counted twice.
These figures come from ERA5, in which the European weather centre ECMWF rebuilds past weather from a weather model and observations, for an area about 28 km across around Bauru, 1991 to 2020. Each change is the difference between one day’s average pressure and the next day’s.

Is the barometer rising or falling in Bauru today?

Is 1013 hPa high or low pressure?
Atmospheric pressure between about 1000 and 1025 hPa is ordinary at sea level. 1013 hPa sits in the middle of that range. In Bauru most days average between 1009 and 1021 hPa. The last 24 hours average about 1012 hPa, within that usual range.
What is normal barometric pressure for Bauru?
From 1991 to 2020 the sea-level average for Bauru was 1015 hPa, and most days average between 1009 and 1021 hPa. It is usually highest in June and July and lowest from November to January.
When does barometric pressure change the most in Bauru?
No time of year stands out: the pressure in Bauru barely changes from one day to the next all year round. Between 1991 and 2020, a typical day’s change was about 1.1 hPa, and a change of more than 10 hPa never happened.
Why does my own barometer show a different number?
Usually altitude, and sometimes the instrument itself. To compare cities, pressure is corrected to sea level. The figure for Bauru, which stands 521 m above sea level, is in the note above: about 60 hPa below the sea-level reading. If your barometer is already set to sea level and still reads slightly differently, that is the setting on the instrument rather than the weather.
Does falling pressure mean rain?
Not by itself. Away from the tropics, falling pressure usually means a low is approaching, and lows carry the fronts that bring cloud and rain, so the two often arrive together. But a shallow fall can pass with nothing more than cloud, and rain falls under steady pressure too. The graph tells you a system is on the way, not how wet it will be. The week ahead, just above, shows the rain forecast beside the pressure.
