Mid and East Antrim — Barometric Trends
Cargan Pressure & Humidity Outlook
For Cargan today, pressure is around 1004 mb, slightly on the low side, with humidity staying high, so low cloud can feel a little more stubborn at times. That can keep things a touch more changeable, with cloud and wind shifts shaping how it feels. The range looks fairly wide across the outlook, so the support for settled weather may come and go. Easing lower later can keep things more mixed at times.
Over the coming days, pressure is likely to sit between 987 mb and 1012 mb in the days ahead. Pressure is projected to edge lower through the period, which can encourage a more changeable feel at times. Humidity looks generally high, which can help low cloud to linger in calmer spells.

FAQ
What is the air pressure in Cargan today?
Atmospheric pressure in Cargan is currently around 1004 mb. It helps describe the broader set-up, while cloud, fronts and local effects still decide the day-to-day detail. Humidity sits near 94%, which can make the air feel damp and increase the chance of haze or low cloud in lighter winds. As the period goes on, the barometer trends down slightly, which can support a more variable, Atlantic-leaning set-up at times.
What counts as high or low pressure in the UK?
In UK terms, pressure in the low 1020s (around 1020 mb–1024 mb) often supports a steadier background, while the low 1000s (around 1000 mb–1004 mb) more often sits closer to passing low-pressure systems. What matters most is the wider pattern and whether pressure is rising or falling.
How does pressure affect wind in Cargan?
Pressure influences wind through the regional gradient. When the pattern tightens, winds can pick up; when it relaxes, winds usually ease.
Does low pressure always mean rain in Cargan?
Not necessarily. Low pressure favours rising motion and cloud development, but rainfall depends on available moisture, frontal features and the track of the system. Some low-pressure days are simply cloudy and breezy with only patchy showers.
What does humidity mean for comfort in Cargan?
It is the amount of water vapour in the air relative to its capacity at that temperature. When humidity is high, evaporation slows and the air can feel damp; when it is lower, comfort and visibility often improve. Moisture levels stay on the higher side overall, so visibility can drop more easily in calmer spells, with low cloud more prone to linger.
