Pressure graph: the past week and the week ahead
The shaded part shows the days already gone. The thicker line is the forecast. The thin dotted line is the average over a whole day, so you can see where pressure is heading under the daily up and down.
Tete has a strong daily rhythm: pressure rises and falls about 6 hPa every day, highest around 08:00 and 22:00 and lowest around 02:00 and 16:00. That wave is most of what the graph shows within a day, so the change since yesterday tells you more here than the change over the past few hours.
Tete sits 137 m above sea level, so a barometer in the city reads about 15 hPa lower than the sea-level figure. A home station set to the local reading should show about 999 hPa as of 13:00.

A typical day’s change through the year
Each date of the year has its own bar. The taller the bar, the bigger a typical day’s change around that date.
Does the pressure change a lot in Tete?
Tete, 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 Tete, 1991 to 2020. Each change is the difference between one day’s average pressure and the next day’s.

Questions about the pressure in Tete
What is the barometer reading in Tete right now?
Sea-level pressure in Tete is 1014 hPa as of 13:00 local time, down 3 hPa over the last three hours, the usual daily fall at this hour. A barometer in the city itself, 137 m up, shows about 999 hPa.
Is the barometer rising or falling in Tete today?
Daily swings aside, pressure has hardly changed over the last 24 hours. It now reads 1 hPa higher than at this time yesterday. Over the last three hours it has gone down 3 hPa, the usual daily fall at this hour.
Has the pressure in Tete changed since yesterday?
Hardly. At this time yesterday it read 1013 hPa; it is 1 hPa higher now.
What has the pressure in Tete been over the last few days?
Over the past 7 days it ran between 1011 hPa (on Wednesday afternoon) and 1021 hPa (on Sunday morning). The biggest change in any 24 hours was a fall of 3 hPa, in the 24 hours ending on Tuesday afternoon. Before today, each day's average was between 1014 and 1017 hPa.
Is 1014 hPa high or low pressure?
Atmospheric pressure between about 1000 and 1025 hPa is ordinary at sea level. 1014 hPa sits in the middle of that range. In Tete most days average between 1008 and 1023 hPa. The last 24 hours average about 1015 hPa, within that usual range.
What is normal barometric pressure for Tete?
From 1991 to 2020 the sea-level average for Tete was 1015 hPa, and most days average between 1008 and 1023 hPa. It is usually highest in July and lowest from December to February.
When does barometric pressure change the most in Tete?
The pressure in Tete changes most from June to November. Between 1991 and 2020, it changed by 5 to 10 hPa from one day to the next on about 8 days a year, and hardly ever by more than 10 hPa.
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 Tete, which stands 137 m above sea level, is in the note above: about 15 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.
