November 2023
The lowest barometric pressure in London since 1989
At 0800UTC on the 2nd November 2023, as storm Ciarán passed over southern England, the barometric pressure recorded at Heathrow airport in London sank to 955.7hPa. Such low baraometric pressures are extremely rare and given the length of the London pressure series, we are able to put that value in the context of the last 300+ years. The table below shows the dates of all sea-level pressures in the series below 960hPa.
