Rising or falling
City pages describe the 3-hour change with the Met Office's barometric tendency terms, the ones used in the Shipping Forecast.
| Term | Change in 3 hours |
|---|---|
| Steady | Less than 0.1 hPa |
| Rising or falling slowly | 0.1 to 1.5 hPa |
| Rising or falling | 1.6 to 3.5 hPa |
| Rising or falling quickly | 3.6 to 6.0 hPa |
| Rising or falling very rapidly | More than 6.0 hPa |

Questions
What is barometric pressure?
The weight of the air above a point, pressing down on it. Weather maps and forecasts report it adjusted to sea level so that readings from places at different heights can be compared. Each city page here shows sea-level pressure.
What is normal barometric pressure?
Standard sea-level pressure is 1013.25 hPa (millibars), which is 29.92 inHg or 760 mmHg. Everyday readings usually sit somewhere between about 980 and 1040 hPa.
What does falling or rising pressure mean?
Falling pressure often comes ahead of cloud, wind and rain as a low-pressure system approaches; rising pressure often comes with clearing, more settled weather. The rate matters as much as the direction, which is why each city page gives the change over the next three hours.
Why does my barometer or phone show a different number?
Many phones and some barometers show station pressure, the actual pressure at your height, which drops by roughly 1 hPa for every 8 metres you climb near the ground. Weather reports, including these pages, show pressure adjusted to sea level.
