Cardiff and the Atlantic: rain on a falling barometer
Cardiff faces the Bristol Channel and the Atlantic beyond, so lows from the west arrive with little in the way. In autumn and winter a falling barometer here usually means rain and wind within hours; the hills of South Wales just to the north add to the rainfall.
Sea level or barometer: 1026 hPa and 1024 hPa in Cardiff

Pressure swings in Cardiff and how you feel
Weather-sensitive people usually notice changes in pressure — especially a fast fall ahead of a front — more than the value itself. That is why it helps to watch the change over the last 3 hours and the last 24.
