Crilly Pressure & Humidity
Mid-Ulster — Barometric Trends
Crilly Pressure & Humidity Outlook
Crilly starts the day with the barometer around 1006 mb, just below the seasonal norm, with high humidity making it feel rather clammy in sheltered spots. That hints at a more mixed backdrop at times, especially if the breeze freshens. Conditions can feel a bit stop–start at times, with the broader signal shifting across the period. A slight fall later on would keep the more changeable edge in play.
Across the next several days, pressure looks set to vary between 989 mb up to 1013 mb over the coming days. 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 Crilly today?
Right now, Crilly is near 1006 mb for atmospheric pressure. Think of it as the background state of the atmosphere; the timing of cloud and rain still depends on the next weather system. Relative humidity is around 95%, meaning the air is very moist; in calmer spells, low cloud or a touch of mist becomes more likely. Later in the outlook, pressure trends lower overall, keeping the background more unsettled at times.
What counts as high or low pressure in the UK?
There is no single cut-off, but as a practical UK guide: the low 1020s (around 1020 mb–1024 mb) often leans more settled, while the low 1000s (around 1000 mb–1004 mb) is more commonly tied to Atlantic lows nearby. The pressure gradient and the direction of travel are usually more telling than the exact number.
How does pressure affect wind in Crilly?
It is not the absolute pressure that matters most, but how steeply it changes from place to place. A sharper gradient can bring brisk winds; a weaker gradient tends to keep winds lighter.
Does low pressure always mean rain in Crilly?
It can raise the risk of showers or rain, but it does not guarantee it. The detail depends on fronts, moisture supply and how the system moves through the region.
What does humidity mean for comfort in Crilly?
Humidity describes how close the air is to being saturated. Higher humidity can feel clammy and can support haze or low cloud in calmer conditions; lower humidity often feels crisper and helps things dry more quickly. Humidity also runs high on average, which can make low cloud or hazier spells more likely when winds are light, especially overnight.
