Data for 08:00 UK time. Sea-level pressure in hectopascals (hPa), which are the same as millibars (mb). “3 h” and “24 h”: change since 3 and 24 hours ago; “Tomorrow”: forecast for the same time.

Pressure yesterday, today and tomorrow: London

Hour by hour, at sea level, in hPa. The dashed line is standard pressure (1013 hPa); the vertical line is now.

High or low pressure: what today’s numbers mean

Standard: 1013 hPa

That is average sea-level pressure (29.92 inHg). Real readings in the UK usually stay within about 980 to 1040 hPa, so one number says little on its own: where it is heading, and how fast, matters more.

Highs and lows

Under high pressure air sinks, clouds break up and the weather settles: sunny and warm in summer, frosty nights and fog in winter. Low pressure brings rising air, clouds, rain and wind.

A fast fall means a change

A drop of 3 hPa or more in 3 hours counts as fast: a front with rain and wind is usually on the way. The table marks it with a double arrow ↓↓.

Why your home barometer reads lower

Forecasts give pressure reduced to sea level, so places can be compared. A barometer measures the pressure where it hangs, and that drops with height: about 1 hPa every 8 metres. With today’s data, an unadjusted barometer would read roughly:

  • Liverpool (about 10 m): about 1028 hPa · 30.36 inHg (at sea level: 1029 hPa)
  • Manchester (about 40 m): about 1024 hPa · 30.23 inHg (at sea level: 1029 hPa)
  • Leeds (about 60 m): about 1023 hPa · 30.20 inHg (at sea level: 1030 hPa)
  • Birmingham (about 140 m): about 1011 hPa · 29.86 inHg (at sea level: 1028 hPa)

Both numbers are right; they just measure different things. To compare your barometer with the forecast, set it to your city’s sea-level pressure. To spot a change in the weather either works — what counts is how much it rises or falls. Each city page shows the pressure at the city’s own height according to the model.

Air pressure and how you feel: what is known

Many people say they can feel the weather change: headaches, tiredness, aching joints or low mood. Studies on migraine and joint pain link these complaints more to changes in pressure — especially a fast fall ahead of a front — than to the value itself, although the results are mixed and everyone reacts differently.

That is why, as well as the reading, we show the change over the last 3 hours and the last 24. If you keep a diary of how you feel, those are the two numbers worth writing down.

This is weather information, not medical advice. If your symptoms are severe or new, talk to your doctor.

Barometric pressure in the Weather 24 app

  1. “Pressure” card on the Today screen: the reading where you are now and its level.
  2. “Pressure over the day”: a 24-hour chart with the standard-pressure line, the low point and the trend.
  3. “Rapid pressure drop” warning card in the app: when pressure is set to fall by more than 15 hPa before the end of the day.
  4. “Pressure” map layer with highs and lows over the UK and Europe.
  5. “Pressure reference” in settings: Local, the pressure at your height, like a barometer, or Sea level, like forecasts and this page. Units: hPa, inHg or mmHg.
  6. “Meteo-sensitivity”: a 0–10 score, hour by hour, with the reasons — pressure change, humidity, wind, temperature swings.

Frequently asked questions

What is the barometric pressure today?
Right now in London the barometric pressure is 1026 hPa (30.30 inHg): high, steady over the last 3 hours (+0.5 hPa). This time yesterday: 1030 hPa; tomorrow the model expects 1024 hPa. Across the 10 cities in the table it ranges from 1026 hPa (London) to 1034 hPa (Edinburgh). Readings update every hour, and each city has its own page with the past week.
What is normal barometric pressure?
Standard sea-level pressure is 1013.25 hPa (the same in millibars). On this page 1009–1023 hPa counts as normal, above 1023 hPa as high and below 1009 hPa as low; above 1033 and below 999 hPa as very high and very low.
Is the air pressure high or low today?
In London it is high right now, at 1026 hPa. The “Level” column in the table shows it for every city. High pressure usually means settled, dry weather; low pressure means clouds, rain and wind are more likely.
Why does my barometer read lower?
Because it measures the actual pressure at your height, and pressure drops with altitude — near the ground by about 1 hPa every 8 metres. Forecasts, and this page, give pressure reduced to sea level so places can be compared. In Birmingham, about 140 m up, an unadjusted barometer reads about 1011 hPa today against 1028 hPa at sea level.
What is the barometric pressure near me?
If you are in or near one of the 10 cities in the table, open its page: it shows the pressure there now, what a home barometer reads at the city’s height and the past week. For your exact location, the Weather 24 app shows the pressure where you are, with the trend over the day.
What will the pressure be tomorrow?
At the same time tomorrow the model expects 1024 hPa in London. The “Tomorrow” column gives the forecast for each city, and the chart shows the next 24 hours.
Where does the data come from?
From weather models via Open-Meteo (CC BY 4.0), hour by hour. These are model values for one point in each city, not readings from a particular station. Official observations and warnings in the UK are published by the Met Office.
