More about air pressure
What we have written about how pressure behaves and how it is measured.
Where air pressure changes the most, city by city
Thirty years of data, ranked by city: where air pressure swings most from day to day and where it hardly moves. London, New York, Tokyo and 128 more.
How much does air pressure change in a day?
A normal day moves the barometer about 4 hPa in London and half of one in Singapore. What counts as a big drop, and how often one comes.
Why barometric pressure deserved its own site
Air pressure is the weather number people ask about most and understand least: is it high, is it rising or falling, does it matter today.

Questions about the pressure in Marāgheh
What is the barometer reading in Marāgheh right now?
Sea-level pressure in Marāgheh is 1017 hPa as of 14:00 local time, down 1 hPa over the last three hours, the usual daily fall at this hour. A barometer in the city itself, 1,470 m up, shows about 860 hPa.
Is the barometer rising or falling in Marāgheh today?
Daily swings aside, pressure has fallen steadily over the past day. That leaves it 3 hPa lower than yesterday at this time. Over the last three hours it has gone down 1 hPa, the usual daily fall at this hour.
Has the pressure in Marāgheh changed since yesterday?
Yes. At this time yesterday it read 1020 hPa; it is 3 hPa lower now.
What has the pressure in Marāgheh been over the last few days?
Over the past 7 days it ran between 1014 hPa (on Saturday afternoon) and 1028 hPa (on Tuesday morning). The biggest change in any 24 hours was a rise of 8 hPa, in the 24 hours ending on Sunday evening.
Is 1017 hPa high or low pressure?
Atmospheric pressure between about 1000 and 1025 hPa is ordinary at sea level. 1017 hPa is on the high side of ordinary.
What is a normal barometric pressure?
Near 1013 hPa at sea level; the exact standard figure, 1013.25 hPa, is the same as 760 mmHg, 29.92 inHg or 101.3 kPa. Anything between roughly 1000 and 1025 hPa is ordinary. Which way it is going matters far more than the number itself.
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 Marāgheh, which stands 1,470 m above sea level, is in the note above: about 157 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.
