Great Harwood Pressure & Humidity
Lancashire — Barometric Trends
Great Harwood Pressure & Humidity Outlook
Great Harwood starts the day with the barometer around 989 mb, decidedly low overall, with humidity neither especially high nor notably low. That keeps the background more unsettled, with conditions more likely to shift as systems move through. 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.
Across the next several days, pressure looks set to vary between 991 mb up to 1023 mb over the coming days. Pressure trends higher through the coming days, favouring quieter spells at times. Humidity looks generally high, which can help low cloud to linger in calmer spells.

FAQ
What is the air pressure in Great Harwood today?
Atmospheric pressure in Great Harwood is currently around 989 mb. It provides useful background context — especially whether the wider pattern leans more settled or more changeable. As the period goes on, the barometer tends to lift, supporting a more settled background pattern at times.
What counts as high or low pressure in the UK?
As a rough guide, the low 1020s (around 1020 mb–1024 mb) tends to be a more settled signal, while the low 1000s (around 1000 mb–1004 mb) more often points to Atlantic influence. The overall pattern matters more than any single reading.
How does pressure affect wind in Great Harwood?
Wind strength is driven mainly by the pressure gradient — how quickly pressure changes over distance. Tightly packed isobars usually mean stronger winds; a slack pattern often allows lighter winds, regardless of whether the headline pressure is high or low.
Does low pressure always mean rain in Great Harwood?
No. Low pressure increases the chance of changeable weather, but the wettest rain bands can miss your area entirely depending on where fronts set up.
What does humidity mean for comfort in Great Harwood?
It reflects how much moisture the air is holding compared with its maximum. Higher values can favour haze or low cloud, especially when winds are light. Humidity is frequently elevated through the period, which can keep the air feeling damp and occasionally reduce visibility in lighter winds.
