Barometric pressure in Eslamshahr

1009hPa
Falling

Beneath its daily wave, pressure has fallen slowly. It stands 1 hPa lower than it did at this time yesterday. That fall is ending: it turns and rises until Tuesday morning.

Sea level reading, as of 20:00 local time. A barometer in Eslamshahr itself reads about 898 hPa.

A quiet week. Nothing moves more than 6 hPa in a day.

What happens next

Pressure tops out near 1012 hPa on Tuesday morning, and falls after that.

The daily rhythm

Eslamshahr has a strong daily rhythm: pressure swings about 6 hPa between a regular low and high, at almost the same hours each day. Most of what the graph shows is that daily wave, which is why the change since yesterday says more here than the change over a few hours.

Your own barometer

Eslamshahr sits 1056 m above sea level, so a barometer in the city reads about 111 hPa lower than the sea-level figure. A home station set to the local reading should show about 898 hPa as of 20:00.

The hours already past are the model's record of each hour as it passed, anchored to real observations, though not a reading from an instrument in Eslamshahr.

Common questions

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. Weather services correct readings to what they would be at sea level, so that cities can be compared. The figure for Eslamshahr, which stands 1056 m above sea level, is in the note above: about 111 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.

Is a millibar the same as a hectopascal?

Yes. One millibar and one hectopascal are exactly the same amount of pressure, so 1013 mbar and 1013 hPa mean the same thing. The name changed; the number did not.

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.
