Overton Pressure & Humidity
Wrexham — Barometric Trends
Overton Pressure & Humidity Outlook
Today in Overton, the barometer sits near 991 mb, firmly on the low side, with humidity in a fairly typical range for the time of year. That favours a more variable day, with timing and wind making the biggest difference. The range looks fairly wide across the outlook, so the support for settled weather may come and go. A gentle rise later on would slightly favour more settled spells.
Over the coming days, pressure is likely to sit between 992 mb and 1027 mb in the days ahead. Pressure trends higher through the coming days, favouring quieter spells at times. Moisture levels fluctuate within a fairly typical range for the time of year.

FAQ
What is the air pressure in Overton today?
In Overton today, pressure is around 991 mb. Think of it as the background state of the atmosphere; the timing of cloud and rain still depends on the next weather system. Later in the outlook, pressure trends a little higher, which can bring quieter interludes 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 Overton?
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 Overton?
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 Overton?
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. Humidity sits in a fairly typical range overall, so comfort and visibility can depend more on wind, temperature and cloud cover day to day.
